Google updates in 2026: core updates, AI answers, more ads and what B2B SaaS teams should adjust

Google's search updates in 2026 so far are two core updates, four spam updates, a closer link between AI Overviews and AI Mode, and more ads inside AI answers. The core updates ran in March and May. On 28 October 2026, Google brought ads in AI Mode to ten more countries and started showing ads in follow-up questions in the US.

This post lists each change with its date, explains what it means for a B2B SaaS website, and ends with what I would adjust now.

Google's 2026 search updates at a glance

I lead search, content and AI visibility at Fourward. Every date and number about Google here comes from Google's own pages, read on 9 November 2026. Where I give advice, I say it's mine.

Which core and spam updates did Google release in 2026?

A core update is a broad change to how Google ranks pages across all sites. A spam update targets pages that break Google's spam policies. Google logs both on its Search Status Dashboard.

Two core updates: March and May

• March 2026 core update. Google released it on 27 March. The rollout was complete on 8 April 2026.
• May 2026 core update. Google released it on 21 May. The rollout was complete on 2 June 2026.
• Timing. For both, Google said the rollout could take up to two weeks. Both rollouts finished within two weeks.

Four spam updates and a Discover update

Google's spam updates started on 24 March, 24 June, 18 August and 24 September 2026. Google also ran a Discover update from 5 February. Discover is the article feed in the Google app. For a B2B SaaS site, I would only check Discover if you publish news-style articles.

If your organic traffic moved between 27 March and 2 June, a core update is one possible cause. Compare the dates before you change any pages.

How AI Overviews and AI Mode changed in 2026

AI Overviews are the AI summaries Google shows above some search results. AI Mode is a separate Google Search mode where people ask longer questions and follow-ups. In 2026 Google started to join AI Overviews and AI Mode.

May: one AI Search experience

• Scale. At its I/O developer event on 19 May 2026, Google said AI Mode has passed one billion monthly users.
• Follow-ups. People can ask a follow-up question right from an AI Overview and continue the conversation in AI Mode.
• One experience. At Google Marketing Live, its yearly ads event, Google said it is bringing AI Overviews and AI Mode into one AI Search experience.
• New Search box. A new Search box began rolling out in every country and language where AI Mode is available.

October: more links inside AI answers

Inline links are links placed on words inside an AI answer. On 15 October 2026, Google said it is launching updates to show inline links higher up in answers, more often. Google is also testing a new display that prominently shows the official sites for a task in AI answers. I covered all five October changes in Google's AI Mode links update.

What did not change

Google's AI features documentation still says there are "no additional requirements to appear in AI Overviews or AI Mode". To be linked, a page must be indexed by Google and eligible to be shown. Both features may also use what Google calls query fan-out: extra related searches run behind one question.

Where Google added more ads in 2026

In my view, the biggest change for paid search this year is that ads moved inside AI answers. Google added new ad formats in May and new countries in October.

New ad formats from May

• Conversational Discovery ads. Google says that with this format, "your ad answers a person's specific question".
• Highlighted Answers. A relevant, high-quality ad can appear on a list of recommendations inside an AI answer.
• Labels. Google says both formats stay labeled "Sponsored".
• AI Max. AI Max is a set of AI features for Search campaigns that Google introduced in 2025. It is now out of beta and available globally.

October: ten more countries and ads in follow-ups

On 28 October 2026, Google expanded ads in AI Mode to Australia, Canada, India, Kenya, Malaysia, New Zealand, Nigeria, Pakistan, the Philippines and Singapore. In the US, it launched multiturn ads, which can show in follow-up questions in AI Mode. Google plans Brazil, Mexico and the United Kingdom next, in Q4 2026.

Google also says click-through rates are already similar for sponsored and organic product list items in AI Mode. That claim is about product listings, so in my view it tells a software company very little.

You can't opt out of AI placements

Google Ads Help says existing Search, Shopping and Performance Max campaigns are automatically eligible for ads in AI Overviews and AI Mode. You can't target ads only to those placements, or opt out of them separately from Search. Results for these placements are included in aggregate, so your reports don't split them out.

How to measure these changes

Search Console's generative AI performance report shows how your site performs in Google's AI features. Google says it reached all websites worldwide as of 31 August 2026.

• What it counts. Impressions, which Google defines as how many times links to your site were shown in a generative AI feature.
• What it covers. AI Overviews and AI Mode.
• What to pair it with. Your own analytics, for visits and sign-ups from Google.

I explained the report step by step in how to see AI Overviews data in Search Console. On the paid side, Google Ads mixes AI placements into your normal Search numbers, as noted above.

What B2B SaaS teams should adjust now

The steps below are my advice, based on the Google pages above. Start with the steps that match where your leads come from.

1. Match traffic drops to update dates. Compare any drop with 27 March to 8 April and 21 May to 2 June. A drop inside those windows may come from a core update, not from a broken page.
2. State product facts in plain sentences. Google is adding more inline links to AI answers. A clear sentence about price, integrations or setup is easier to quote and link than a pricing graphic.
3. Give each buyer task one official page. Pricing, free trial, demo, login, security and docs should each have one current page on your own domain. Redirect old copies so Google knows which page is official.
4. Keep docs and help pages indexable. Some help centres sit behind a login or block crawlers. Google can't link a page it can't index. I built Fourward's free AI visibility check, which runs 30 checks on what AI engines can read about a site.
5. Review paid search more often. Your Search campaigns can already show in AI answers, and you can't opt out. Check search terms and budgets more often, and judge results by qualified leads, not clicks.
6. Report AI impressions every month. Track generative AI impressions for your top pages in Search Console, next to sign-ups from organic search.

GEO (generative engine optimization) means making your pages easy for AI answers to find, quote and link. Our GEO guide for B2B SaaS covers the content side in seven steps.

Mistakes to avoid after this year's updates

• Rewriting pages during a rollout. Wait until the dashboard says the rollout is complete, then compare before and after.
• Paying for special AI markup. Google says no special optimizations are needed to appear in AI Overviews or AI Mode.
• Reading ad results as AI results. Google Ads reports AI placements in aggregate, so a change in clicks may not come from AI answers.
• Using shopping data for software decisions. Google's click-through claim is about product listings, not B2B searches.
• Hiding key facts. Facts that only sit in PDFs, images or pages behind a login are harder for Google to quote.
