Yoast SEO on other platforms
Next to Yoast SEO for WordPress, we’ve developed Yoast SEO for several other platforms in partnership with some great companies.
We have a full Yoast SEO for TYPO3 module, both free and premium.
We currently do not maintain a Yoast SEO for Drupal, because our relationship with its developer has ended. We're looking at new opportunities here so stay tuned.
