Google rolls out broad core updates several times a year. Most are minor adjustments. The May 2026 core update was significant — affecting an estimated 15–20% of queries globally and causing substantial ranking changes across multiple industries, including local services, health, and professional services.
What Google's Core Updates Actually Do
A core update changes how Google evaluates and ranks content across its entire index. Google is constantly trying to surface the most "helpful, reliable, people-first content." Core updates recalibrate the weighting of hundreds of signals — it's not about a specific penalty, but a wholesale re-evaluation of what deserves to rank where.
The May 2026 update showed a clear focus on E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) signals and strongly rewarded locally-relevant content from businesses with clear physical presence and real customer reviews.
Who Was Affected
Winners ✓
- Local businesses with genuine Google reviews
- Sites with clear author expertise and credentials
- Content that directly answers searcher intent
- Fast-loading, mobile-optimised sites
- Sites with strong internal linking structure
Losers ✗
- Thin pages with keyword-stuffed content
- Sites with no clear author or business identity
- Pages copied or lightly re-written from competitors
- Slow sites with poor Core Web Vitals scores
- Sites relying heavily on AI-generated filler content
How to Check If You Were Affected
Open Google Search Console and compare your click and impression data from May 1–15, 2026 against the same period in April 2026. A drop of more than 15–20% in organic clicks that aligns with the update period suggests you were affected. Also compare your average position for key search terms.
What to Do Now
- 1Audit your content quality. Review your most important pages. Would an industry expert be proud to have written them? If not, rewrite them with real depth and genuine insight.
- 2Add author information. Make it clear who wrote what, with real names, photos, and credentials where relevant.
- 3Build local signals. Ask satisfied clients for Google reviews. Update your Google Business Profile with current hours, photos, and posts.
- 4Be patient. Recovery from a core update sometimes requires waiting until the next core update. Focus on quality improvements now, and the next update will likely reward you.
