WordPress E-E-A-T: Building Author Authority Signals for Search

Google’s E-E-A-T framework (Experience, Expertise, Authoritativeness, Trustworthiness) is the lens through which Search Quality Evaluators rate content quality, and it directly influences rankings for Your Money or Your Life (YMYL) topics. For WordPress sites, E-E-A-T is not a plugin setting — it is a collection of structured data, page architecture, and content signals that collectively tell Google a real expert created and stands behind the content.

Problem: A WordPress site's content is written by multiple contributors with varying levels of topic expertise, and there are no structured signals — author credentials, citations, update frequency — that indicate experience, expertise, authority, and trustworthiness to search engines.

Solution: Build E-E-A-T signals programmatically: add Person JSON-LD to author archive pages linking to external profiles with sameAs, register a custom credentials meta field on the user object and include it in Article schema output, add a dateModified field to all post schema, and display a visible "Reviewed by" byline with structured data. Measure impact in Google Search Console's Performance report.

The code below adds Person schema to author archive pages, attaches author schema to single posts via Yoast-compatible filters, creates an author box with social profile links, and sets up the sameAs connections that let Google cross-reference expertise across the web.

        '@type'    => 'Person',

NOTE: sameAs links in schema are only as valuable as the profiles they point to — a LinkedIn profile with no posts, a GitHub with no activity, and a Twitter account with two tweets provide no trust signal; E-E-A-T is earned through consistent, attributed publishing across platforms over time, and the schema merely helps Google discover those existing signals rather than creating them from nothing.
