Yoast SEO is the most popular WordPress SEO plugin, with 10+ million active installs. It provides on-page SEO analysis, XML sitemaps, meta tag management, and readability scoring for WordPress and WooCommerce sites.
Yoast SEO and StoreVitals solve different problems at different points in the content lifecycle. Yoast helps you optimize pages before and during publishing — it's a content creation tool. StoreVitals monitors what happens after you publish: does the page still load? Are links broken? Is your SSL valid? Did a new app break your security headers? WooCommerce stores benefit from running both: Yoast for on-page optimization, StoreVitals for continuous health monitoring. Shopify, BigCommerce, and other platform stores can only use StoreVitals — Yoast requires WordPress.
