I came to a years old post, discussing Microdata, RDFa etc. I looked on the microformats2 site and it says both have been superseded by microformats2. Also Google uses microformats2 for SEO.
Should I only use microformats2 these days if I want to start with SEO? Is it the de facto "standard"? There are extra HTML5 tags to sort of "mark" content as some type of microformat, e.g new tags like <time>
and <article>
. Do those tags have the same meaning or relevance for search engines like if I would tag them directly with microformat classes (like class="h-article", etc.)?
