Google SEO Updates 2026: What Changed and What to Do

Core and spam updates this year

Google lists every confirmed ranking update on its Search Status Dashboard. These are the ones since December 2025:

What to do: don’t change anything in panic while an update is rolling out. When it’s finished, compare Search Console for the weeks before and after. Google says there is no specific fix for a core update drop: improve the usefulness of your pages and wait — recovery can take until a later update. A spam update only hurts if a site uses spammy tactics such as bought links or scaled low-value pages.

Search Console now shows AI Overviews and AI Mode

On 3 June 2026, Google introduced generative AI performance reports in Search Console, and by 31 August they had rolled out to all websites worldwide. For the first time you can see how often your pages appear in AI Overviews, AI Mode and AI features in Discover.

• Metric: impressions — how often your URLs appeared in these AI features.
• Breakdowns: pages, countries, devices (Search only) and dates.
• The data is also included in the main Performance report.

Google’s official advice on AI search

In May 2026 Google published a guide to optimizing for generative AI features in Search. Its message is that SEO fundamentals remain the foundation, and that the content that wins is valuable, unique and “non-commodity” — something readers can’t get from a hundred other pages.

Google’s documentation on AI features is direct: there are no additional requirements to appear in AI Overviews or AI Mode, and you don’t need new machine-readable files, AI text files or special schema markup. A page needs to be indexed and eligible to show with a snippet — the same as normal search.

Image searches are now in Search Console

Since 24 September 2026, Search Console includes data from multimodal searches — when people search with an image through Google Lens, Circle to Search, an image upload or Chrome’s right-click image search. Look for the new multimodal search type filter in the Performance report.

If you sell products, run a restaurant or do design work, this shows whether your photos bring visitors. Use clear original photos, descriptive file names and alt text.

New spam rules: back button hijacking and site reputation

• Back button hijacking (announced April 2026, enforced from 15 June): any script that stops visitors from returning to Google with the back button — for example by inserting fake pages or ads in browser history — now breaks Google’s spam policy. It can come from ad networks or plugins, so test your site’s back button on mobile.
• Site reputation policy (updated August 2026): this targets sites that host third-party content to exploit their own reputation (for example, renting out a section to coupon or casino content). Google changed how its manual actions apply inside the European Economic Area. For most small businesses the lesson is simple: don’t rent out pages or subdomains on your site.

A shared control for AI training (coming in 2027)

On 30 October 2026, Google said it plans to support a shared robots.txt token for AI training, based on IETF work, so one line can tell several AI companies not to train on your content. Google aims to support it with other AI providers in 2027. It is about AI training, not Google Search rankings. Until it arrives, Google’s existing control is the Google-Extended token in robots.txt.

What this means for your website

1. Open the Performance report and the new AI report in Search Console once a month.
2. Fix pages marked “Crawled – currently not indexed” and 404 errors — AI answers only cite indexed pages.
3. Write specific, experience-based content instead of generic text; avoid bulk AI pages.
4. Stay away from backlink sellers, and remove ad scripts that hijack the back button.
5. Keep collecting reviews and genuine mentions — they help both search and AI answers.
6. Be patient after an update: SEO takes time, and quick reactions often make things worse.
