Quick answer: The biggest SEO change is AI search: Google's AI Overviews and AI Mode, plus tools like ChatGPT, now answer many questions directly. Google also folded its helpful content system into core ranking, added new spam policies, added Experience to E-A-T and replaced FID with INP. The response is the same: clear, accurate, first-hand content.

Most "SEO trends" lists are predictions. This one is a record of what actually changed, with a source for each item, as of October 2026. Below each change is what I'd do about it if you run a dental practice or a home service business.

Google launched AI Overviews in the US in May 2024 (Google) and opened AI Mode to all US users in May 2025 (Google). People also ask ChatGPT, Gemini and other assistants for recommendations directly.

What Google says to do: "There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary" (Google Search Central). Your pages need to be indexed and eligible to show in regular search.

What I'd do: put a direct answer at the top of each important page, keep your business facts (name, address, phone, hours, services) identical everywhere, and check what AI tools say about you every month. This is the work people now call AEO (answer engine optimization) and GEO (generative engine optimization), and it's what my AEO and GEO service covers.

2. Helpful content became part of core ranking

In March 2024, Google folded its helpful content system into its core ranking systems and added three spam policies: scaled content abuse, expired domain abuse and site reputation abuse (Google Search Central).

What I'd do: stop publishing thin pages made only to rank, such as a page per suburb with the same text. Fewer, more useful pages usually beat many weak ones. If you've used AI to produce lots of near-identical pages, review them.

3. E-A-T became E-E-A-T

In December 2022, Google added "Experience" to the quality rater guidelines, making it E-E-A-T: experience, expertise, authoritativeness and trust, with trust the most important (Google Search Central). Raters don't rank pages directly, but the guidelines show what Google is aiming for.

What I'd do: show who's behind the business. Add real team photos, credentials and author names, describe your actual process, and keep reviews coming in.

4. INP replaced FID in Core Web Vitals

Interaction to Next Paint (INP) replaced First Input Delay as the responsiveness metric in March 2024 (web.dev). It measures how quickly the page responds when someone taps or clicks, across the whole visit.

What I'd do: check the Core Web Vitals report in Search Console. Heavy chat widgets, tracking scripts and page builders are the usual causes of slow responses on small-business sites.

5. Mobile-first indexing is finished

Google completed its move to mobile-first indexing in 2024. Sites that don't work on mobile devices can't be indexed (Search Engine Land).

What I'd do: make sure everything on your desktop site, including service details, booking buttons and structured data, also appears on the mobile version.

6. Several familiar features are gone

  • FAQ and How-to rich results: since 2023, FAQ rich results show only for well-known government and health sites, and How-to results are gone (Google Search Central).
  • The cache: operator and cached links: retired in 2024. My guide to Google search operators lists which ones still work.
  • Google Business Profile chat and call history: ended July 31, 2024 (Google Business Profile Help).
  • Universal Analytics: stopped processing data in July 2023. Google Analytics 4 replaced it (Analytics Help).
  • Mobile-Friendly Test: retired in December 2023. Use Lighthouse or PageSpeed Insights instead.

What hasn't changed

Pages still need to be crawlable and indexed. The page that answers the searcher's question most clearly still tends to win. Local businesses still live or die by their Google Business Profile, reviews and consistent details. If those basics are weak, fix them before chasing anything new. My SEO basics guide covers them.

How to keep up

Google lists confirmed ranking updates on its Search Status Dashboard and explains bigger changes on the Search Central blog. Check both when your traffic moves suddenly, before you change anything.
