Google's March 2026 Core Update is one of the most significant algorithm changes of the year, and early tracking data from multiple industry sources paints a clear picture of what Google is now prioritizing. Pages that reword existing top results without adding fresh data, proprietary insights, or unique perspectives are losing ground fast. This helps explain why SEO Stuff customers who invested in original frameworks, proprietary data, and expert-led content are maintaining and gaining visibility while competitors relying on templated content are falling. https://t.co/eh1auroJF7 Here is what the early data shows about who got hit: According to ALM Corp, Affiliate sites were the hardest hit category. 71% of affiliate sites tracked across multiple industry analyses experienced negative ranking impact. The common pattern: thin comparison pages, templated review content, and pages that add no original evaluation or first-hand testing. These sites built traffic on repackaging other people's information, and Google has now made it clear that repackaging alone is not enough. AI content farms took heavy losses. Sites that scaled production using AI to generate large volumes of generic content without human editorial oversight, original data, or genuine expertise saw traffic drops that early reports place between 50% and 80%. The content got indexed, and some of it ranked briefly, but the March 2026 update aggressively devalued content that contributes nothing new. Sites with original research gained ground. Early tracking data shows that sites investing in proprietary data, original studies, first-hand experience, and expert-driven content saw an average visibility gain of roughly 22%. This is not a coincidence: these are the exact content types that score highest on information gain because they contain data and perspectives that no other page on the internet has. (If you want to see where your site stands across Google and AI search, start here: https://t.co/Pn764BHwyL) This update also landed alongside the March 2026 Spam Update (March 24-25), which hit just days before the core update rolled out on March 27. The combination made March 2026 one of the most disruptive months for SEO in years, with over 55% of tracked sites reporting noticeable ranking changes within the first few days. Here is why information gain matters more now than ever: Google has always said it rewards helpful content. But historically, "helpful" was loosely defined enough that a well-structured page covering a topic comprehensively could rank even if it did not add anything new. The March 2026 update tightened that definition. Google is now evaluating whether a page contributes something the existing top results do not. If your page covers the same ground as the pages already ranking, with no additional data, no original analysis, no first-hand experience, and no unique framework, it is structurally disadvantaged in the new ranking environment. Here is what to do with this data: Audit your content for information gain. Go through your top pages and ask one question: does this page contain anything that the other pages ranking for this query do not have? If the answer is no, that page is vulnerable to the kind of ranking loss the March 2026 update is causing. Add original data wherever possible. Proprietary studies, internal benchmarks, survey results, case study metrics, first-hand testing results: anything that makes your content the primary source rather than a secondary summary. Google is now measurably rewarding pages that are the original source of information. Move away from templated content at scale. The affiliate model of producing hundreds of comparison pages using the same template with interchangeable products is losing effectiveness. Each page needs to demonstrate genuine evaluation, original testing, or unique editorial judgment. Invest in expert attribution and E-E-A-T signals. Content tied to named experts with demonstrable experience in the topic performs significantly better under the new ranking environment.
