SEO in 2026: 8 Things That Actually Changed

Most “SEO trends” articles are predictions. This one only includes developments verifiable as of 20 October 2026 in Google's official announcements, documentation changelogs and the Search Status Dashboard.

For each item I note what changed, when, and what I now do differently with clients. I keep the full list of updates in the Google updates log.

Short answer: The changes felt most in 2026 were AI Overviews and AI Mode launching in Türkiye on 18 February 2026, FAQ rich results disappearing on 7 May 2026, a steady run of core and spam updates, and new reports in GA4 and Search Console. The fundamentals did not change; where visibility happens and how it is measured did.

1. AI Overviews and AI Mode launched in Türkiye

Google Türkiye's blog post of 18 February 2026 announced that AI Mode and AI Overviews were rolling out gradually in Türkiye, built on the Gemini 3 model family. AI summaries and conversational search are now part of everyday Turkish search.

One measurement detail matters: AI Mode and AI Overviews data counts toward the Search Console Performance report totals; in addition, Google announced separate generative AI performance reports for these surfaces in June 2026 and said on 31 August 2026 that they were available to all sites. I cover the local impact in Google AI Mode in Türkiye and how to become a cited source in the GEO implementation guide.

2. FAQ rich results ended and structured data got leaner

Google announced that FAQ rich results would stop appearing in Search from 7 May 2026 and removed the documentation on 15 June 2026. HowTo rich results had already gone. FAQPage markup remains valid and can help machines understand content, but it no longer brings a visual gain in results.

This was not a one-off; several structured data types were retired through 2025 and 2026:

In practice I have moved schema work away from chasing rich results and toward types that describe the entity, such as Organization, Product and Article; details are in the schema and structured data guide.

3. Core updates: the calendar and continuous smaller updates

The Google Search Status Dashboard lists five core updates since March 2025:

In December 2025, Google added to its core updates documentation that it continually updates its algorithms, including smaller core updates, without waiting for the next major one. Fluctuations on unannounced dates are therefore normal. To diagnose a drop, I use the core update traffic drop checklist.

4. Spam policies expanded and spam updates came faster

The Search Status Dashboard shows spam updates in August 2025 and in March, June, August and September 2026. The policy text changed too:

• 13 April 2026: a “back button hijacking” section was added to the malicious practices policy.
• April 2026: Google clarified that spam reports may be used for manual actions.
• 15 May 2026: Google clarified that spam policies also apply to generative AI responses in Search.
• 28 August 2026: the site reputation abuse policy was updated, with different enforcement in the EEA.

In practice: templated pages at scale, rented subfolders and tricks to trap users on a page now sit more clearly within policy.

5. A generative AI guide arrived and llms.txt was clarified

On 15 May 2026 Google published a new guide on appearing in generative AI features in Search and, the same day, clarified that spam policies apply to those responses too.

So I treat llms.txt not as a ranking lever for Google but as an optional file for other AI systems; the llms.txt guide explains what it does and does not do.

6. Preferred sources expanded to AI Mode and AI Overviews

Google published site owner documentation in January 2026 for the feature that lets users pick a site as a “preferred source”. On 30 April 2026 it became available in all languages where Search is offered, and on 27 May 2026 it began rolling out to AI Overviews and AI Mode.

The documentation says a chosen site's content is more likely to appear in Top Stories and can carry a “preferred” badge in AI surfaces; only domain- and subdomain-level sites qualify. Publishers should test Google's button or deep link.

7. GA4 reports AI assistant traffic as its own channel

Since May 2026, GA4's default channel group includes a separate channel for traffic from AI assistants. Visits that used to disappear into Referral can now be reported on their own.

The channel shows clicks from assistants such as ChatGPT or Perplexity, but not the visibility you get when an answer mentions you without a click. Setup and interpretation are covered in AI traffic in GA4.

8. Search Console now reports social and video platforms

In July 2026 Google announced that Instagram, TikTok, X and YouTube accounts can be added to Search Console as platform properties, along with a guide to analyzing that content. The help page says the feature is rolling out gradually; it measures how that content performs on Google surfaces (Search, Discover, News), not views inside the platforms themselves.

Content outside your website can now be tracked on Google from Search Console too. For brands with video, the first steps are in the video SEO article.

We can work out together how these changes should shape your priorities: I work on search as an SEO consultant and on AI surfaces as a GEO consultant; a short intro call is a good start.
