Google rolled out a core update in early March 2026 with broad ranking impact across U.S. small business categories. The patterns we observed across the AdsTalent partner network's portfolio echo what we have seen in prior updates: thin content lost ground, expertise-signaling content gained, and AI-generated content without human editorial review took the worst hit.
What we observed
Across the small business sites we monitor, three patterns showed up consistently:
- Sites with high-volume, low-substance content lost rankings. Pages built for keyword targeting with little informational value dropped, often by significant margins. This included sites that had aggressively published AI-generated content without editorial review.
- Sites with deep, specific content gained. Pages that answered specific questions with specific information, written by or reviewed by people who actually know the subject, climbed.
- E-E-A-T signals mattered more than they used to. Experience, expertise, authoritativeness, and trustworthiness signals tied to a real business with a real history and real customer relationships carried more weight in the rankings shake-out.
Who got hit
The sites that lost the most ground in this update:
- Affiliate sites and review sites that aggregated information without adding meaningful original analysis.
- Local service sites that had thin location pages and almost no content depth on services.
- Sites that scaled AI-generated content without an editorial layer.
- Sites with manipulated review profiles or aggressive link schemes.
Who recovered
Sites that had been on a longer-arc content quality investment, sites with strong review profiles tied to real customers, and sites with clear authorship and expertise signals tied to actual people generally held position or gained.
What to do if your site dropped
The right response depends on what dropped and by how much:
- Diagnose, do not react. Pull the data on which pages and which queries lost ground. Look for patterns. Is the drop concentrated on thin pages, low-quality content, or specific keyword categories.
- Strengthen the content that is closest to recovery. Rather than rebuilding from scratch, identify the pages that are one or two improvements away from recovering and start there.
- Build E-E-A-T signals. Author bylines tied to real people, links from credible sources, customer reviews on credible platforms, and content that demonstrates actual expertise.
- Do not panic-publish. Adding more low-quality content makes the problem worse. The recovery path is quality, not volume.
Most sites that drop in a core update either recover gradually as quality improves or stay flat. The ones that recover are the ones that respond by improving the underlying content asset, not by chasing the algorithm with quick fixes.
