WPInterface SEO can import from Yoast SEO, Rank Math, All in One SEO, SEOPress, The SEO Framework and Slim SEO (SEO → Tools). It copies titles, descriptions, focus keywords, robots settings, canonical URLs, social fields, primary categories and settings. The other plugin’s data is never changed or deleted.
No duplicate tags
While another SEO plugin is still active, WPInterface SEO pauses its front-end output so your pages never get two sets of tags. A notice explains this. Deactivate the other plugin once you have imported, and output starts automatically.
Redirects are the exception: they keep working even while another SEO plugin is active. You can import redirects from Redirection, Rank Math, Yoast SEO Premium, Slim SEO and SEOPress too; see Redirects and the 404 log.
