External services

StackMime SEO can load Google’s tag (Analytics 4 or Tag Manager), only after you enter an ID in its settings, and with consent mode only after the visitor accepts. It then sends page views, device details, IP addresses and call and email clicks to Google, under Google’s terms and privacy policy.

The Check destinations button requests each redirect target from your own server to read its status. Nothing about your site or visitors is sent.

Use one SEO plugin at a time, because two will both print titles and tags. The launch checks warn you if Yoast SEO, Rank Math or All in One SEO is active.

It improves the one WordPress already makes at /wp-sitemap.xml: noindex pages leave it, author and taxonomy sitemaps can be removed, and last-modified dates are added.

Under SEO → Redirects, import a CSV with the old address, the new address and optionally the status code. Then click Check destinations to make sure each one lands on a working page.

The plugin sets no cookies and sends nothing anywhere. If you add Analytics, switch on consent mode and use a consent plugin that supports the WP Consent API.

Choose the second language under SEO → Settings, then set each page’s language and pick its translation in the StackMime SEO box. Both pages then point at each other with hreflang.

Yes. Add a 301 from each old address or import them as a CSV, check the destinations, then watch the 404 log for anything you missed.
