Yoast SEO is one of the most widely used WordPress plugins — and one of the most misunderstood. Installing it does not improve your rankings. Configuring it correctly does. And even then, Yoast only handles part of what SEO actually requires.
Here is what actually matters in the Yoast setup, and what you can safely ignore.
The settings that make a real difference
- Site representation — Tell Yoast whether you are a person or an organisation, and fill in your name, logo, and social profiles. This feeds into the schema markup Yoast generates automatically
- Search appearance defaults — Set sensible default title and description templates for posts and pages. These appear in Google results when no individual SEO title has been set
- XML sitemap — Enable it and verify it is including the right content types. Then submit the sitemap URL in Google Search Console
- Indexing rules — Tell Yoast which content types and archives should be indexed by Google and which should not. Tag pages, date archives, and author pages often add no value and are better excluded
- Open Graph — Enable social sharing metadata so links shared from your site display correctly on LinkedIn, Facebook, and other platforms
What Yoast cannot do for you
Yoast cannot write content that ranks. It cannot choose the right keywords. It cannot fix your site speed or your hosting. A green traffic light in Yoast means the page meets certain readability and keyword density criteria — it does not mean the page will rank.
The strategy behind the content — who you are targeting, what they are actually searching for, and whether your content genuinely answers it — is what determines results. Yoast helps you implement that strategy. It does not replace it.
