Author bylines with credentials
Real bylines on every piece, linked to author pages with biography, credentials, and external profiles. This matters for YMYL content especially.
Citations to primary sources
Link out to original research, not just aggregator sites. It signals you're contributing to the web, not repackaging it.
Content freshness
Last-updated dates visible on every article. Refresh content that's gone stale. Stale content on YMYL topics ranks lower over time.
