Yoast SEO

Yoast SEO is one of the most widely installed SEO plugins for WordPress. It adds a panel under each post where you set the search title and meta description, see a preview of how the post might look in results, and get readability and focus-keyword checks as you write.

Behind the scenes it also handles site-wide basics such as XML sitemaps, canonical tags and structured data, which saves a blogger from configuring them by hand. A paid version adds features such as redirects, support for several keyphrases per post and AI-generated title and description suggestions.

The traffic-light scores are guidance, not goals. A post can rank well with an orange light, and chasing green by repeating a keyword usually makes writing worse. Use the plugin to get titles, descriptions and technical settings right, then write for the reader.
