exactly it just dossn´t count the words in the page titles and meta descriptions, since they aint rly an part of the content.

Hi there

If you make a force https redirect, all youre old redirects will be automaticly forced to https, but i would recommend you if you used http:// in the redirect string to update this to https://, since you will reduce the redirecs on youre site.

Google and users rly dont like redirects, so try to update the links you have out there on other sites instead, but ofc. a redirect is better than a link ending up with an 404 and thats why we need to use the 301 and 302 redirects.

For rest of the guide to move youre site to SSL, that is actually a great and fully working guide. So follow it and go ahead with the transfer

Yoast does analyze every content on youre page to calculate the prominent words. But no it dosn´t count meta descriptions and titles (unless titles is youre headline). Since this content aint rly a part of youre "content".

Hope that was the answer youre looking for
