Well, i removed site because I did not see the usefullness and i try to optimize for pagespeed also. But of course I can add it back.
For description, it’s already in almost all page as it dynamically use the title to generate discription content, see any news or doc page source. If needed I’ll add it to the landing page too.
Well, I try to avoid any kind of external request, 3rd party trackers etc. but maybe you think about plugins that are privacy friendly which I don’t know?
Maybe yes, but it’s not so bad, these analyzis were before the correction you provided, and I also add specific news sitemaps for google, which should improve seo a little more. The most errors there are a lack of words in some articles, or duplicate titles.
But as said above, sometimes, a seo improvement brings a pagespeed degradation, so at one point each line has to be chosen carefully. Also I’m working on website accessibility, which is a quite big work as it needs to refactor many parts to respect some query of better contrast, for instance.
