Schema.org - is it necessary to do it, does it affect SEO?

Question

Search Engine Optimization

csgoseller.ru- do I need to do microdata for this site?

Answer 1

She is loved by both Google and Yandex, which they openly write about. And not necessarily schema.org, there are other types of microdata that are understood by the main search engines.
Do it, it won’t take much time to add it, and the pages will become more noticeable. It definitely can't get any worse :)

Answer 2

The impact on SEO depends on the search engine. Yandex loves this markup very much, but Google doesn’t give a damn about it. But it can improve how your site appears on the search page. Add an icon, a picture, some categories and all sorts of little things (you need to familiarize yourself with what and how is done in the mana of search engines). That in itself will attract attention. So it's worth applying.
