90+ SEO Statistics for 2026: Search Behavior, AI Overviews, and Ranking Data

These SEO statistics open with the number that anchors everything else: Google still handles 89.92% of worldwide search traffic. But the bigger story in 2026 is what happens after the query is typed.

AI Overviews now trigger on roughly 16% of all searches, tied to hundreds of millions of daily click decisions, and the SEO playbook built around ten blue links is being rewritten in real time.

This roundup pulls together the search behavior, AI search, ranking, keyword, backlink, technical, content, local, mobile, and industry data every SEO, marketer, and founder needs to plan for the rest of the year.

Quick answer: Google holds 89.92% of the global search engine market (StatCounter, August 2026), while AI Overviews now appear on close to 16% of all queries (Semrush, November 2025), reshaping how much of that traffic actually reaches a website.

Key stats at a glance:

  • Google's global search engine market share sits at 89.92% (StatCounter, August 2026)
  • AI Overviews grew from appearing on 6.49% of queries in January 2025 to 15.69% by November 2025 (Semrush)
  • The number one organic Google result gets an average click-through rate of 27.6% (Backlinko)
  • 96.55% of all indexed pages get zero monthly organic traffic from Google (Ahrefs, December 2023)
  • The average SEO agency retainer costs $3,209 per month, against $1,348 for freelancers (Ahrefs, April 2026)

Search Engine Market Statistics

Search engine market share sets the baseline for every other number in this article: it tells you which platform's algorithm actually decides who gets found.

Google's dominance has held remarkably steady for over a decade, even as challengers pick off single-digit slices at the margins.

  1. Google holds 89.92% of the global search engine market across all devices, with Bing at 4.31%, DuckDuckGo at 0.7%, Baidu at 0.52%, Yahoo at 0.46%, and Yandex at 0.45% (StatCounter, August 2026).
  2. Bing's share has climbed from roughly 3% for most of the 2010s to its current level, a shift tracked alongside its Copilot AI integration (StatCounter, 2026).
  3. DuckDuckGo has grown from a zero share in 2010 to its current level worldwide, and to close to 2% in the United States (StatCounter, 2026).
  4. Ahrefs' Content Explorer index shows 96.55% of all pages get zero traffic from Google, and only 1.94% get between one and ten monthly visits (Ahrefs, December 2023). This figure predates 2024 and has not been publicly re-measured by Ahrefs at the same scale since, but it remains the most-cited benchmark of its kind and no fresher large-sample study has superseded it.
  5. Search demand itself is not shrinking: Google continues to process more than 5 trillion searches per year, an figure Google itself has confirmed applies through the current search era (Search Engine Land, reporting Google's own disclosure).
  6. Google's AI Overview feature has expanded to more than 100 countries and over 40 languages since its rollout, according to Google's own product announcement (Google, May 2025 update).
  7. Google confirmed at its 2026 developer conference that AI Mode, the conversational successor to AI Overviews, surpassed one billion monthly users within a year of its debut, with query volume more than doubling every quarter since launch (Google I/O 2026, reported by TechWyse).

Google's grip on search is not loosening in any way that changes strategy: if you optimize for Google, you are optimizing for effectively nine in every ten searches performed anywhere in the world.

The real disruption to search behavior in 2026 is not coming from a rival search engine. It is coming from what Google itself now shows above the traditional results, which is where the next section picks up.

AI Search and AI Overview Statistics

AI Overviews are the single biggest change to the search results page since featured snippets, and the data on how often they appear, what they cite, and how they affect clicks is still moving month to month.

  1. AI Overviews were triggered on 6.49% of queries in January 2025, rose to 24.61% in July 2025, then settled at 15.69% by November 2025, based on an analysis of more than 10 million keywords (Semrush, December 2025).
  2. The share of AI Overview-triggering queries that are purely informational fell from 91.3% in January 2025 to 57.1% in October 2025, as commercial and transactional intent expanded (Semrush, December 2025).
  3. Commercial queries triggering an AI Overview grew from 8.15% to 18.57% of all AIO-triggering queries over the same period (Semrush, December 2025).
  4. Transactional queries triggering an AI Overview grew from 1.98% to 13.94% over the same period (Semrush, December 2025).
  5. Navigational queries triggering an AI Overview, including branded searches, grew from 0.74% to 10.33% between January and October 2025, a sign that even brand-name searches are no longer immune (Semrush, December 2025).
  6. Science was the most AI Overview-saturated industry in Semrush's November 2025 snapshot at 25.96% of keywords, followed by Computers & Electronics at 17.92% and People & Society at 17.29% (Semrush, December 2025).
  7. Real Estate and Shopping had the least AI Overview saturation of any industry tracked, at under 3% of keywords, largely because those queries depend on local packs, maps, and transactional SERP features that AI summaries cannot replace (Semrush, December 2025).
  8. When Semrush isolated keywords that gained an AI Overview between May and October 2025, the zero-click rate for those same terms moved from 33.75% before the AIO appeared to 31.53% after, challenging the assumption that AI Overviews automatically suppress clicks (Semrush, December 2025).
  9. Overall, keywords with AI Overviews still carry a higher zero-click rate than keywords without one, but that gap has narrowed steadily since January 2025 rather than widened (Semrush, December 2025).
  10. Google's own spam policy update formally defines "scaled content abuse," covering mass-produced low-value pages regardless of whether AI or humans created them, and links this pattern to indexing suppression and ranking instability (Google Search Quality Rater Guidelines).
  11. Google confirmed it now lets users jump directly from an AI Overview into a full AI Mode conversation, a change that extends the search session well past the original query into follow-up questions a page was never written to answer (Google, reported by TechCrunch, January 2026).
  12. US Google searches ended without a click 68% of the time during a January-to-April 2026 study window, based on Similarweb desktop and mobile panel data (SparkToro, 2026).
  13. During that same study period, only 0.34% of Google searches transitioned into a full AI Mode conversation, suggesting AI Mode's current traffic share is still small next to AI Overviews even as its user base grows (SparkToro, 2026).
  14. Research cited alongside the SparkToro study found that 92% to 94% of AI Mode sessions end without any click to an external website, a notably higher zero-click rate than standard Google search (Semrush, cited in SparkToro's 2026 report). The business impact of that shift is already visible at major publishers, as reported by The Wall Street Journal, which found organic search referrals to several large news sites falling sharply since AI Overviews expanded.

Zero-Click Search Statistics

A dedicated look at zero-click behavior rarely gets its own section in most SEO roundups, even though it is arguably the single most consequential shift in how search traffic behaves.

  1. 68% of US Google searches ended without a click between January and April 2026, according to Similarweb panel data (SparkToro, 2026).
  2. AI Mode sessions specifically end without a click 92% to 94% of the time, compared to a lower rate for AI Overview-triggered searches and a lower rate still for standard organic results without any AI feature present (Semrush, cited in SparkToro, 2026).
  3. Zero-click behavior is not new: comparable research years earlier already showed a majority of desktop searches ending without a click, and the trend has only continued upward as more answer-style SERP features have been added (SparkToro methodology notes, 2026 report).

The direction of travel is clear even where the exact percentage is still moving: AI Overviews are spreading from purely informational queries into commercial and even branded search, and the SEO response to that has to be different from the response to a simple ranking-factor update.

Ranking well is no longer the finish line. Getting cited inside the answer is starting to matter just as much, which is exactly where traditional ranking and click-through data still carries the most weight.

Google Search Behavior, Ranking, and CTR Statistics

Click-through rate by position is one of the most re-measured numbers in SEO, and it is also one of the clearest examples of why methodology matters: three reputable studies analyzing millions of search results each arrive at a different number for the same question.

  1. The number one organic result in Google has an average click-through rate of 27.6%, based on an analysis of more than 4 million Google search results across 1.3 million pages (Backlinko).
  2. The number one organic result is 10 times more likely to be clicked than a result in position ten, according to the same Backlinko analysis.
  3. Moving up a single position in Google's results increases relative click-through rate by 32.3% on average (Backlinko).
  4. Organic click-through rates for positions eight through ten are nearly identical to each other, meaning a small ranking gain near the bottom of page one rarely moves traffic in a meaningful way (Backlinko).
  5. A separate Sistrix analysis of more than 80 million keywords found the first organic result averaging a 28.5% click-through rate, with position two at 15% and position three at 11% (Sistrix, reported by Search Engine Journal).
  6. That same Sistrix study found click-through rate for position one swings between 13.7% and 46.9% depending on the query, showing just how much individual search intent affects any single-number average (Sistrix, reported by Search Engine Journal).
  7. When a search results page includes a Google Knowledge Panel, click-through rate for the first organic position drops from an average of 28% to just 16%, because many searchers get their answer without scrolling past the panel (Sistrix, reported by Search Engine Journal).
  8. Pages ranking in Google's top 10 are more than three years old 72.9% of the time, underlining how much of first-page real estate is held by older, established content (Ahrefs).
  9. Only 1.74% of newly published pages reach the top 10 search results within one year for at least one keyword, according to Ahrefs' analysis of ranking timelines (Ahrefs).
  10. The top-ranking page for a given keyword is not always the page that receives the most total search traffic for that topic; Ahrefs found this happens only 49% of the time, since a page can rank lower for its target term while ranking highly for dozens of related queries (Ahrefs).
  11. There is no meaningful correlation between a page's Flesch Reading Ease score and its Google ranking position, according to Ahrefs' analysis of readability across ranking pages (Ahrefs).
  12. 30.9% of featured snippets are pulled from a page that also ranks in position one for the same query, meaning roughly seven in ten featured snippets come from a page ranked lower on the same results page (Ahrefs).

The two headline studies land within roughly a percentage point of each other, but neither used the same sample, date range, or device mix, which is why "the" click-through rate for position one is best treated as a range rather than a fixed number.

CTR by position tells you what happens once a searcher sees your result. The next question is whether your page is even structured around the right keywords to show up for that searcher in the first place.

Keyword Statistics

Keyword-level data has not changed as dramatically as the AI search numbers, but a few figures are consistently misunderstood, particularly around search volume and how much of it actually goes to the long tail.

  1. 94.74% of all keywords get ten or fewer monthly searches, which is the mathematical reason long-tail strategies still outperform head-term chasing for most sites (Ahrefs).
  2. Only 0.0008% of all keywords get more than 100,000 monthly searches, meaning the handful of head terms every industry fights over represent a vanishingly small share of total search volume (Ahrefs).
  3. Google Ads Keyword Planner overestimates true search volume 54.28% of the time when checked against actual Google Search Console click and impression data, and is only roughly accurate 45.22% of the time (Ahrefs).
  4. 46.08% of all clicks recorded in Google Search Console go to "hidden" or anonymized queries that Google does not report individually, based on an analysis spanning nearly 9 billion total clicks across more than 146,000 websites (Ahrefs).
  5. Search terms between 10 and 15 words long receive 1.76 times more clicks than single-word queries, reflecting how much more specific and lower-competition long-tail phrasing tends to be (Backlinko).
  6. URLs that contain a keyword related to the search term earn a 45% higher click-through rate than URLs that do not, based on Backlinko's click-through rate dataset.

Ranking for the right keywords only pays off if the page can actually earn authority for them, and authority in Google's system still runs largely through backlinks, however much that model is being tested by AI search.

Backlink Statistics

Backlinks remain one of the most measured and most misunderstood ranking signals in SEO. The data below covers how many links actually survive, how they are distributed, and what still correlates with rankings.

  1. At least 66.5% of links pointing to a sample of more than 2 million websites since January 2013 have rotted, meaning they no longer resolve to their original destination (Ahrefs Link Rot Study).
  2. Counting temporary errors and other issues alongside confirmed dead links, a total of 74.5% of the links in that same Ahrefs sample are effectively lost for ranking purposes (Ahrefs Link Rot Study).
  3. A separate Pew Research Center study measuring general webpage disappearance, rather than backlinks specifically, found 38% of webpages that existed in 2013 were no longer accessible a decade later, a notably lower rate than Ahrefs' link-specific figure because it measures a different thing (Pew Research Center, reported by Internet Archive's blog).
  4. A 2026 analysis of more than 865,000 actively monitored backlinks found 56% still live and resolving correctly, with an average backlink lifespan of about 20 months (Linkody, June 2026).
  5. That same 2026 dataset found backlink survival drops from 89% at three months old to 31% after five years, described as a survival curve rather than a single decay rate (Linkody, June 2026).
  6. 77% of the backlinks in that 2026 monitored dataset are dofollow, while barely 1.6% use a rel="sponsored" or rel="ugc" attribute (Linkody, June 2026).
  7. There is a positive correlation between the number of websites linking to a page and that page's search traffic, a pattern Ahrefs has confirmed across large-scale ranking studies (Ahrefs).
  8. Pages ranking in position one tend to gain new followed backlinks from new referring domains at a pace of 5% to 14.5% per month, according to Ahrefs' backlink growth study.
  9. URLs with a larger number of distinct anchor text variations pointing to them from internal links are highly correlated with more Google search traffic (Zyppy internal links study).
  10. Pages with at least one exact-match anchor text link have at least five times more organic traffic than pages without any exact-match anchors, based on Zyppy's internal link analysis.

The three figures disagree because they measure different populations: Ahrefs tracks links into a fixed 2013 cohort of sites, Pew tracks general webpage survival, and Linkody tracks a live, continuously refreshed panel of monitored links rather than a historical cohort.

A backlink is only worth building if the page it points to can actually be crawled, rendered, and served fast enough for Google to want to rank it, which is where technical SEO comes in.

Technical SEO Statistics

Technical SEO issues are unglamorous, but they are also some of the most consistently documented problems in the entire field, thanks to annual large-scale accessibility and performance audits.

  1. 95.9% of the top one million home pages on the web had at least one detectable Web Content Accessibility Guidelines failure in 2026, up from 94.8% in 2025 (WebAIM Million, February 2026).
  2. The average home page carried 56.1 distinct accessibility errors in 2026, up from 51 errors per page in 2025, a 10.1% year-over-year increase (WebAIM Million, February 2026).
  3. Low-contrast text was found on 83.9% of home pages in 2026, up sharply from 79.1% the year before, and remains the single most common accessibility failure measured (WebAIM Million, February 2026).
  4. 53.1% of home pages are missing alternative text on at least one image, with more than one in four linked images carrying no descriptive text at all (WebAIM Million, February 2026).
  5. The average home page grew to 1,437 distinct page elements in 2026, a 22.5% increase in a single year and nearly double the element count recorded in 2019 (WebAIM Million, February 2026).
  6. Because of that rising page complexity, WebAIM estimates a user with a disability will encounter an accessibility error on roughly one in every 26 page elements they interact with (WebAIM Million, February 2026).
  7. Structured data enrichment correlates with a roughly 25% higher click-through rate for enhanced pages, based on Rotten Tomatoes' rollout of structured data across 100,000 unique pages, documented in Google's own developer case study (Google for Developers).
  8. Users spend 1.5 times longer on pages that implement structured data compared to pages that do not, and AMP pages with search features see 3.6 times higher interaction rates than AMP pages without them, per the same Google-published case study (Google for Developers).
  9. 88.5% of survey respondents named slow loading time as the top reason visitors abandon a website, while 73.1% pointed to poor mobile responsiveness as a major issue (GoodFirms survey).

Fixing the plumbing gets a page eligible to rank. What a site publishes on top of that plumbing, meaning the actual content, is the other half of the equation, and it is where publishing habits have shifted noticeably over the past three years.

Content Marketing Statistics

Orbit Media's annual survey of working bloggers is one of the few datasets in SEO that has run long enough, and consistently enough, to show real multi-year trend lines rather than a single snapshot.

  1. The average blog post length peaked at 1,427 words in 2023 and has since declined to 1,333 words in 2025, as content teams shift toward writing fewer, more targeted long-form pieces rather than maximizing word count (Orbit Media Annual Blogger Survey).
  2. The average time to write a typical blog post peaked at 4 hours and 10 minutes in 2022 and had settled to 3 hours and 48 minutes by 2024 (Orbit Media Annual Blogger Survey).
  3. Only 21% of bloggers reported "strong results" from their blog in the 2025 edition of the survey, down from 26% two years prior, with declining organic search traffic cited as the primary factor (Orbit Media Annual Blogger Survey).
  4. Bloggers who spend six or more hours on a typical post are 50% more likely to report above-average results than those who spend less time, based on Orbit Media's survey data.
  5. Content over 3,000 words generates 77.2% more backlinks than short-form content under 1,000 words, according to IncRev's content-length analysis.
  6. Headlines between 14 and 17 words drive 76.7% more social shares than shorter headlines, based on the same IncRev study.
  7. 92% of surveyed SEO professionals believe their competitors buy links, according to Editorial Link's link-building survey, a figure worth noting alongside Google's explicit policy against paid link schemes.
  8. 44.02% of surveyed companies choose to keep link building entirely in-house rather than outsourcing it, per Editorial Link's survey data.

Content strategy sets what gets published. Whether that content ever reaches a nearby customer at all is largely a local SEO question, and local search behavior looks different from broad informational search in almost every respect.

Local SEO Statistics

Local search is driven more by trust signals like reviews than by the classic backlink-and-keyword mechanics that dominate national SEO, and the annual BrightLocal consumer survey is the closest thing the industry has to a definitive source on how people actually use those signals.

  1. 97% of consumers read online reviews for local businesses at least occasionally, according to BrightLocal's 2026 Local Consumer Review Survey.
  2. 71% of consumers use Google specifically as their review platform of choice when evaluating a local business, per the same 2026 BrightLocal survey.
  3. Customers are 2.7 times more likely to consider a business reputable if they find a complete Business Profile on Google Search and Maps, based on Google's own published guidance for business owners.
  4. Customers are 70% more likely to visit, and 50% more likely to consider purchasing from, a business with a complete Google Business Profile, according to the same Google source.
  5. 76% of people who perform a smartphone search for something nearby visit a business within a day of that search, based on Google's own consumer research.
  6. 28% of local smartphone searches for something nearby result in a purchase, per the same Google research.

Local search still runs on the same underlying Google index as everything else on this list, which means the mobile, voice, and video behavior covered next applies just as much to a "plumber near me" search as it does to a global brand query.

Mobile, Voice Search, and Video SEO Statistics

Mobile has been the majority search surface for years, but the more interesting movement in 2026 is happening in video, where marketer adoption has plateaued at a record high even as reported ROI satisfaction has dipped.

Mobile Search Statistics

  1. Mobile devices accounted for 62.73% of global website traffic in the second quarter of 2025, having crossed the 50% mark back in 2020 and climbed steadily since, based on StatCounter data compiled by Statista.
  2. Google holds an even larger share of the mobile search market than it does overall, exceeding 95% of mobile search traffic according to StatCounter's mobile-specific market share tracker.

Video SEO Statistics

  1. 91% of businesses now use video as a marketing tool in 2026, matching the category's all-time high after a brief dip the prior year (Wyzowl State of Video Marketing Survey, 12th edition).
  2. 82% of marketers say video marketing delivers a good return on investment in 2026, down from 93% the year before, a shift Wyzowl attributes to more businesses producing video without a clear strategy behind it rather than to video itself losing effectiveness (Wyzowl, 2026).
  3. 85% of consumers say they have been convinced to buy a product or service after watching a brand's video, based on Wyzowl's 2026 survey.
  4. 93% of marketers consider video an important part of their overall marketing strategy, per the same Wyzowl dataset.

SEO Industry, Pricing, and Salary Statistics

SEO pricing and compensation data is harder to pin down than search behavior data because so much of it is self-reported, but Ahrefs' recurring provider and salary surveys are among the largest and most transparent datasets publicly available.

  1. The average SEO monthly retainer across 439 surveyed providers is $2,917, with agencies averaging $3,209 per month and freelancers averaging $1,348 per month (Ahrefs SEO Pricing Survey, updated April 2026).
  2. The average hourly rate for SEO services is $111, and only about one in ten providers charge more than $150 an hour (Ahrefs SEO Pricing Survey, 2026).
  3. 78.2% of SEO providers charge using a monthly retainer model, making it by far the most common pricing structure in the industry (Ahrefs SEO Pricing Survey, 2026).
  4. SEO consultants specifically average $3,250 per month, a figure close to agency pricing despite consultants typically operating with lower overhead (Ahrefs SEO Pricing Survey, 2026).
  5. The median annual salary for SEO professionals was $58,288 in 2024, up 18.4% from $49,211 the year before, based on Ahrefs' salary survey of working SEOs (Ahrefs SEO Salary Survey, 2024).
  6. The share of surveyed SEOs identifying as content specialists rose to 55.1% in the 2024 survey from 36.9% the year before, while those identifying as technical specialists fell slightly and those identifying as link-building specialists dropped to just 5.3% (Ahrefs SEO Salary Survey, 2024).
  7. The share of surveyed SEOs working in-house rose to 57.9% in 2024 from 42.3% the year before, while the agency-employed share fell from 49.5% to 33.5% over the same period (Ahrefs SEO Salary Survey, 2024).
  8. The global search engine optimization services market is projected to grow from $92.74 billion in 2025 to $108.28 billion in 2026, a 16.8% compound annual growth rate, according to a market report distributed through ResearchAndMarkets (The Business Research Company, January 2026).
  9. That same report projects the SEO services market will reach $203.83 billion by 2030, growing at a 17.1% compound annual growth rate over the back half of the decade (The Business Research Company, January 2026).

How These Statistics Were Compiled

Every figure in this article was traced to its original publisher rather than taken from a secondary listicle.

The source hierarchy followed, in order, was: the organization that ran the original study or owns the data (StatCounter, Ahrefs, Semrush, WebAIM, Wyzowl, BrightLocal, Google, Orbit Media, Linkody), that organization's own summary of its research, or established trade press naming the primary source by name.

No figure was pulled from a page that itself only cited an aggregator, and no statistic appearing on any of the three competing articles reviewed for this piece was reused unless its original primary source could be independently located and confirmed.

Figures generally reflect data published or updated in 2025 or 2026. Two exceptions are flagged explicitly in the text where they appear: Ahrefs' 96.55%-zero-traffic figure (published December 2023) and the Ahrefs SEO Salary Survey (published in 2024), both included because no larger or more recent study has publicly superseded them at the same sample size.

Where two credible sources measured a related question differently, such as click-through rate by position or backlink decay rates, both figures are shown side by side in a source-comparison table with a note on why the methodologies produced different numbers, rather than picking one and discarding the other.

This page will be reviewed and re-verified again as 2026 data continues to be published.

Conclusion

Two patterns cut across every category in this roundup. First, search is fragmenting at the results-page level even as Google's overall market share barely moves: AI Overviews, AI Mode, and zero-click behavior are all reshaping what happens after a query without changing who runs the underlying search engine.

Second, the fundamentals that have driven SEO for over a decade, meaning backlinks, page speed, accessibility, and consistent publishing, still show a measurable, repeatable relationship with rankings and traffic, even as search itself becomes increasingly mediated by AI summaries.

For anyone building an SEO strategy off these SEO statistics, the practical takeaway is to treat ranking as necessary but no longer sufficient.

A page still needs the backlinks, technical health, and keyword targeting the data above describes, but it now also needs to be structured so an AI Overview can quote it accurately, since citation inside an AI answer is quickly becoming as valuable as the ranking position that used to guarantee a click.

FAQ

What percentage of Google searches trigger an AI Overview?

Roughly 15.69% of all Google queries triggered an AI Overview as of November 2025, after peaking near 24.61% in July 2025, based on Semrush's analysis of more than 10 million keywords (Semrush, December 2025).

What is a good click-through rate for the number one Google result?

Backlinko's large-scale study found the average click-through rate for position one to be 27.6%, while a separate Sistrix study of 80 million keywords put the figure at 28.5%. Either number is a reasonable benchmark, since the two studies used different samples and time frames (Backlinko; Sistrix via Search Engine Journal).

How many SEO statistics show that backlinks still matter in 2026?

Multiple SEO statistics in this list confirm it: Ahrefs has documented a positive correlation between referring domains and search traffic, pages ranking in position one gain new followed backlinks at 5% to 14.5% per month, and pages with an exact-match anchor text link get at least five times more traffic than pages without one (Ahrefs; Zyppy).

How much does SEO cost in 2026?

The average SEO monthly retainer is $2,917 across all provider types, with agencies averaging $3,209 per month and freelancers averaging $1,348 per month. The average hourly SEO rate is $111 (Ahrefs SEO Pricing Survey, updated April 2026).

Do zero-click searches mean SEO is less valuable?

Not necessarily. While 68% of US Google searches ended without a click between January and April 2026, that has not stopped the SEO services market from being projected to grow from $92.74 billion in 2025 to $108.28 billion in 2026, since ranking and AI citation both still drive brand visibility and conversions even when the click itself does not happen (SparkToro, 2026; The Business Research Company, January 2026).

How much has web accessibility changed in the past year?

It has gotten measurably worse rather than better: 95.9% of the top one million home pages had a detectable accessibility failure in 2026, up from 94.8% in 2025, and the average number of errors per page rose from 51 to 56.1 over the same period (WebAIM Million, February 2026).

Is long-form content still worth writing for SEO?

The data is mixed but leans yes for authority-building. Content over 3,000 words earns 77.2% more backlinks than content under 1,000 words, yet the average blog post length has actually declined from 1,427 words in 2023 to 1,333 words in 2025 as writers favor more targeted long-form pieces over simply maximizing word count (IncRev; Orbit Media Annual Blogger Survey).

What share of SEO professionals now work in-house versus at agencies?

57.9% of surveyed SEOs worked in-house in 2024, up from 42.3% the year before, while the agency-employed share fell from 49.5% to 33.5% over the same period, according to Ahrefs' SEO Salary Survey.
