Yoast SEO
Yoast SEO is a wappalyzer technology that ScanMalware.com has fingerprinted across 1,307 public website scans. Each of those scans is a real headless-browser visit, so the data on this page reflects how Yoast SEO is actually deployed on the live web — including on compromised, phishing and malware-hosting sites, not just legitimate ones.
On sites where Yoast SEO appears, the technologies most often detected alongside it are PHP, MySQL and Open-Graph-Protocol. That co-occurrence pattern is a useful fingerprint of the stack Yoast SEO typically ships with, and a starting point for spotting deployments that look unusual.

How ScanMalware detects Yoast SEO
Yoast SEO is detected by analysing the response headers, HTML markup, JavaScript runtime and asset URLs captured when ScanMalware loads the site in a real headless browser.
From any scan you can pivot into related signals — JARM TLS fingerprints, ASN ownership and BGP routing, certificate history, JavaScript analysis and the overall security verdict — to understand not just that Yoast SEO is present, but how it is being used.
