Uncover the Reasons Behind Website Disappearances Following Google’s May Updates and How to Bounce Back
Recent data reveals a concerning trend linked to Google’s May Updates, with numerous websites disappearing from search results. The Semrush Sensor has recorded an unprecedented peak, signalling widespread fluctuations in site rankings. According to SE Ranking, a staggering 79.5% of the top three URLs have experienced significant shifts. Search Console dashboards are now inundated with a new status: “Crawled — currently not indexed.”
Stay Calm: Proven Strategies to Tackle Google’s Deindexing Challenges
Understand That Google’s May Updates Indicate a Major Structural Change, Not Merely a Ranking Shift
The core update from Google, which began on May 21, 2026, at approximately 08:40 PDT, is expected to conclude by June 4. This update is notable not only for its ranking instability but also for a marked deindexing trend that has been surfacing since early April. This period coincided with the launch of Gemini 3.5 Flash, enhancing AI functionalities within Search. This evolution is crucial for SEO teams monitoring their analytics; the key question is not whether changes have happened, but how to react effectively.
Identify the Deindexing Trend Initiated by Google’s May Updates Starting in March
The rise of “Crawled — currently not indexed” statuses began long before the May update. SEO experts pointed out this phenomenon shortly after the March 2026 core update (from March 27 to April 8), and it has persisted since then.
A growing number of sites report their pages are being crawled but not indexed.
The following sequence has been noted:
- – Googlebot successfully crawls the page
- – The page undergoes processing
- – However, it fails to enter the indexed corpus
This scenario is different from a manual action or penalty.
It reflects an algorithmic decision — the Google’s May Updates system has determined that your content currently lacks adequate value for indexing.
Marie Haynes, the founder of Marie Haynes Consulting, remarked during community discussions: “This aligns with the introduction of Gemini 3.5 Flash, which now powers the AI features in Search.”
Some fluctuations observed in the initial five days may indicate variations in AI Mode rather than being directly associated with the core update itself.”
This attribution challenge adds to the confusion. When faced with simultaneous changes in AI Mode visibility, core update ranking adjustments, and deindexing trends, pinpointing the exact cause of these shifts can become nearly impossible.
Understanding the Significance of YMYL and Aggregator Sites: The Early Leaders in Volatility
Historical trends show that certain sectors face greater susceptibility to changes. The health, finance, and legal fields have shown the most substantial fluctuations within the first 72 hours, consistent with patterns evident in every core update since March 2024.
A critical observation is that aggregator platforms are suffering the most significant impacts.
Websites that host or syndicate content from other creators are experiencing disproportionate volatility. Lily Ray, VP of Organic Strategy at Amsive, identified a clear trend from March 2026: “Winners consist of first-party, authoritative sources, as Google prioritises visibility towards credible, brand-owned, and government domains.”
This trend is not new — however, it is intensifying. Google’s May updates seem to impose stricter quality signals on content that primarily exists to aggregate or repurpose rather than create original material.
If your site falls within the aggregator category, the increase in deindexing you are experiencing may not stem from a technical issue that can be easily resolved. Instead, it could be a consequence of Google’s algorithmic evaluation indicating that your content lacks sufficient original value.
Why It’s Essential to Comprehend the March 2026 Baseline 
Before reacting to fluctuations on Day 5, consider this: Glenn Gabe (GSQi) pointed out that the March 2026 update displayed its most significant swings during Days 7-12, rather than within the initial week.
A similar pattern may be unfolding now. As Christian Ott (SEO-Kreativ) mentioned on Day 2 of this update: “The initial ranking shifts within the first 3-4 days are not reliable indicators. Patience is vital.”
Use the March data as your reference point:
– Semrush Sensor peaked at 9.5/10 — the highest ever recorded
– 79.5% of top-3 URLs shifted across tracked keywords
– 90.7% of top-10 URLs shifted — only 9.3% maintained their exact positions
May is mirroring similar trends. Interpreting Day-5 declines as permanent losses is the most detrimental mistake SEO teams can make during this rollout.
Establish a 14-Day Recovery Plan for Google’s May Updates
Drawing from patterns observed in March and collective community insights, here’s a structured framework for navigating Days 6-14:
Days 6-8: Resist Making Hasty Changes
- – Avoid deleting content — give time for the pattern to clarify
- – Document baseline positions — capture screenshots of Search Console data while it is still recent
- – Identify URLs with the “Crawled — currently not indexed” status — prioritise these in your action plan
Days 9-11: Distinguish Between Genuine Issues and Noise
- – Compare pre/post positions with the March baseline percentages
- – Identify pages that are genuinely deindexed versus those that have merely shifted — different issues necessitate different solutions
- – Evaluate AI Mode visibility separately from traditional organic visibility — understanding attribution is crucial
Days 12-14: Initiate Targeted Actions
- – For URLs that have been deindexed: Focus on enhancing content quality, improving internal linking, and strengthening page authority signals
- – For aggregator sites: Assess whether your content offers sufficient original value to compete with first-party sources
- – For YMYL verticals: Emphasise E-E-A-T signals — ensure author expertise, accurate citations, and dependable sources
What Does Google’s May Updates Statement Truly Imply?
Google’s official communication from SearchLiaison states: “This is a regular update aimed at better highlighting relevant, satisfying content for searchers across all types of sites. There is no additional action creators need to take for this update, provided they create satisfying content designed for people.”
Pay close attention to the wording: “satisfying content designed for people” — not content optimised solely for search engines, not content that aggregates from other sources, nor thin AI-generated output.
The message is clear. If your website’s deindexing or ranking declines coincide with low-quality, thin, or recycled content, this update is functioning as intended. The solution is not technical; it is foundational.
Your Essential Monitoring Checklist
Track These Signals Daily Until June 4:
- Search Console Coverage report — monitor changes in the “Crawled — currently not indexed” count
- Ranking positions for your top 20 keywords — document both losses and unexpected gains
- AI Mode visibility (if available in your Search Console) — separate this from traditional organic visibility
- Traffic patterns — differentiate between traffic loss driven by ranking changes and that driven by AI Mode
- Index coverage — ascertain which types of pages are most affected (homepage, blog posts, category pages)
Key Takeaways from Google’s May Updates
The May 2026 core update is unprecedented in one significant aspect: it is the first major update to roll out during Google I/O week, coinciding with a major AI model deployment. This creates attribution challenges that have not been present in previous cycles.
The core message remains consistent: Google seeks original, authoritative, and people-first content.
If you are experiencing deindexing or ranking drops:
- – Do not panic on Day 5 — the most significant movements often occur in Week 2
- – Avoid attempting to optimise your way out — if content quality is the issue, technical fixes alone will not suffice
- – Assess the risks of being an aggregator — if you syndicate or repurpose content, the model is now less favourable towards you
- – Track your performance separately — AI Mode results and traditional organic results are now distinct KPIs
The sites that thrive through this update will not be those with superior technical SEO. They will be those that provide the most satisfying, original, and people-first content.
This guidance is crucial. It is being applied with increasing consistency in Google’s May Updates.
