The situation

A regulated cannabis-adjacent publisher in a YMYL category lost 71% of its organic visibility across a single core update. The standard agency response — “add more content, build more links” — was not just wrong, it was actively harmful in a vertical where the platform’s risk filters treat volume as a negative signal.

The diagnosis

The site had authority by the old proxy (links) and none by the new one (entity trust). Its claims were confident, unsourced, and indistinguishable from a thousand affiliate pages. To a quality classifier — and to a language model’s retrieval head — it read as untrustworthy by construction.

The approach

  1. Entity consolidation. A single, schema-anchored author entity with verifiable credentials replaced the anonymous byline.
  2. Claim sourcing. Every health-adjacent assertion was hedged, dated, and tied to a primary source. Confidence copy was rewritten as defensible prose.
  3. Statement structuring. Claims and their evidence were co-located so they survived chunking intact.

The result

Recovery began at the classifier’s measured 60–90 day resample cadence and compounded over two quarters: +212% against the trough, and — the metric that now matters — a 4.1× increase in LLM citation share for the site’s core claims. The recovery held because it was structural, not cosmetic.

The lesson

In the hardest vertical in search, the winning move is the one that scales to all of them: trust is built at the level of the claim, not the page.
