A supplement e-commerce brand was generating 33k monthly organic sessions but couldn't break through on competitive head terms due to thin authority and weak E-E-A-T signals.
A 12-month full SEO subscription: monthly guest posts on health publications (DR 50–75+), E-E-A-T signals via expert bylines, technical audit fixes, and structured data implementation.
Monthly organic sessions grew from 33k to 80k. Revenue from organic increased by 67%. Domain Rating rose from 34 to 61.
Health supplements is a YMYL category where Google's E-E-A-T requirements are enforced most strictly. 33k monthly sessions was already meaningful, but the brand had plateaued — unable to rank for competitive head terms where DR 50+ competitors with expert-authored content dominated.
Why YMYL Sites Need a Different Approach
Google's Quality Raters evaluate health content against strict Experience, Expertise, Authoritativeness, and Trustworthiness criteria. A supplement site without visible expert authorship, medical review disclosures, and third-party citations from credible health sources will struggle regardless of on-page optimisation.
The client's content was good, but it lacked E-E-A-T signals. Articles were published without author attribution. No expert review process was visible. The link profile was sparse and dominated by generic directories rather than health-specific editorial placements.
The 12-Month Plan
Quarter 1: Foundations
- Full technical SEO audit — identified 23 critical issues including crawl blocks and missing structured data
- Added author pages with professional credentials for all content contributors
- Implemented Article and Product schema across category and product pages
- First batch of health publication guest posts to begin authority signalling
Quarters 2–3: Authority Build
Monthly guest posts on DR 50–75+ health, wellness, and nutrition publications. Each placement included author bylines that linked back to the site's expert author pages — reinforcing the E-E-A-T signal loop. Content was written by a qualified nutritionist to ensure editorial acceptance.
Quarter 4: Consolidation
With domain authority established, the final quarter focused on pushing the highest-value commercial terms. Niche edits on aged health content accelerated ranking movement for product category keywords.
The fastest E-E-A-T improvement came from a single change: adding credentialed author names and bios to every article. Google's quality systems detect this signal quickly — we saw measurable ranking improvement within 6 weeks of implementation.

We'd been trying to crack the health keyword space for two years. Understanding that E-E-A-T wasn't just about content but about the whole authority signal system — expert authors, credible links, structured data — was the shift that made everything else work.
