Google uses social profile links and sameAs schema to verify an organization's identity and build entity associations that strengthen E-E-A-T — especially important for YMYL topics.
Organization or Person schema with sameAs to explicitly connect your site to social profilesCheck the site's footer, header, and About page for links to social media profiles. Verify the links go to the correct, active official profiles. Check for Organization or Person JSON-LD schema with a sameAs array listing social profile URLs.
Add links to active social profiles in the site footer using recognizable icons or text labels. Add or update Organization / Person schema with a sameAs array containing all official social profile URLs (LinkedIn, Twitter/X, Facebook, etc.).
Explain how social profile links help search engines build an entity graph for the organization, how this contributes to E-E-A-T, and why linking to inactive profiles is counterproductive.
Review metadata generation, rendered HTML, structured data, and response headers related to Link to active social profiles. Flag exact routes or templates where search-facing output violates the rule, and describe how to verify the final page output.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 22 cases were attempted. The headline lift of +5 percentage points is the difference between those two pass rates over the 22 comparable cases.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
