Anyone who interprets this as a blanket signal against AI-powered writing is mistaken. Google clearly distinguishes between AI as a tool and AI as a replacement for substance. The difference determines whether a page fares better or worse after the rollout.
What differentiates the update from its predecessor
The March 2026 Core Update was a broad recalibration – volatility across all sectors, with Helpful-Content- Signaling as a central lever. The May update is more targeted. According to Semrush The volatility value during the rollout period was 78 out of 100, Sistrix recorded 65 out of 100, Accuranker 72 out of 100 – all of them clearly above normal values.
Three sectors were particularly hard hit: Finances, Jobs and Bless you. According to Sun There, visibility shifted primarily toward sources considered the top destination for the respective search intent—away from aggregators and generic advice sites.
What Google means by AI Slop
"AI Slop" refers to AI-generated text produced in bulk that lacks editorial value, fact-checking, and a discernible expert perspective. In its official communications, Google has consistently emphasized that it is not the production tool that matters, but the result. The May update makes this clearly visible in practice.
Domains that filled thousands of largely identical URLs with automatically generated text – be it „keyword + city“ or „product + variant + category“ – lost across the board. Where no human reviewed it, no proprietary data point was incorporated, and no author was identifiable, the algorithm resorted. Conversely, those who produced with AI assistance, revised editorially, incorporated their own experience, and made authorship transparent, reportedly remained. Search Engine Land by this update largely untouched.
Substance over scaling
On the winning side, a consistent picture emerges. Pages with genuine user reviews, authentic product descriptions, and demonstrable experience gained ground. This strikes the core of E-E-A-T – Google's Quality Rater Guidelines Experience, Expertise, Authority and Trustworthiness.
Those who credit authors, link to sources, contribute their own data, and highlight firsthand knowledge send exactly the signals that the algorithm rewards. Content that feels like a copy of the top 10 results—just with a slightly different sentence structure—loses out. This is a must for anyone who has previously published AI-generated text without editorial review.
Typical characteristics of the update winners:
- Transparent authorship with linked author profile
- Your own data, test results, or real-world examples as content anchors
- Visibility in AI Overviews (Google SGE) – Websites cited as sources in AI responses saw disproportionately high growth
- Clear source structure with external supporting documents
- A consistent brand experience across all URLs
What to do now – after the rollout
The update is complete. Conclusions drawn during the ongoing rollout are noise – now the clean analysis begins. Those who lost rankings between May 21 and June 2 face the question of whether there's a quality issue or if new SERP features are pushing organic results down. Both look in the Google Search Console right from the start.
A good place to start: a content audit for all pages experiencing a loss of visibility—organized by URL type. Programmatic pages, how-to guides, and transactional pages have different underlying causes and require different Answers.
Practical steps for the next two weeks:
- Export rankings from Google Search Console and compare it with the data as of May 20—exactly before the rollout
- Create URL clusters by page type: programmatic, editorial, transactional
- Identify the biggest losers and formulate a hypothesis for each cluster—authorship, lack of sources, lack of original contribution
- SERP Analysis for affected keywords: check whether organic clicks Featured Snippets, Knowledge Panels or AI Overviews were deducted
- Pilot content revision – revise one page per cluster, evaluate results after four weeks
- Enter author profiles, where they are missing – Name, photo, and a link to a profile page are sufficient as an initial signal
FAQs on the Google May 2026 Core Update
The Google May 2026 Core Update was completed on June 25, 2026.
The May 2026 Core Update started on May 21, 2026, and was officially declared finished on June 2, 2026. The rollout thus lasted just under twelve days – slightly shorter than the initially announced two weeks.
Which sectors were particularly affected?
Pages in the finance, jobs, and health sectors were particularly hard hit. Job portals saw an average increase in visibility of 15 to 20 percent, while YMYL (Your Money or Your Life) pages without demonstrable authorship and source structure lost ground.
What is AI Slop and why is it losing visibility?
AI Slop refers to mass-produced AI-generated content without editorial added value, without verifiable facts, and without recognizable authorship. Google assesses content substance – if this is lacking, the algorithm sorts accordingly.
May I make changes immediately after the update?
Since the May update was completed on June 2nd, targeted revisions based on a content audit are now sensible. Google generally recommends waiting until the rollout is fully complete before taking action.
How do I tell if my loss of visibility is caused by algorithms or SERP features?
Comparing clicks and impressions in Google Search Console provides insights: If impressions and clicks fall simultaneously, an algorithmic reassessment is likely. If impressions remain stable while clicks decrease, new SERP features like AI Overviews or Featured Snippets are displacing organic traffic.
