Do html tags - article, header and footer affect SEO?
And such a question, if you super structure the site according to all SEO requirements, all the tags in the right places, etc., is there a guarantee that the site will appear on the first page of the search engine? Or do you need to buy a bunch of links for this? Or wait until people themselves begin to distribute site links? And in general, is it possible to get to the first pages of the issue only by super structuring the site?

Answer 1

The optimization of the header and the validity of the site code as a whole affect. help.yandex.ru/webmaster/recommendations/intro.xml

Answer 2

They influence, but the most important thing is the CONTENT, as terrible sites sometimes hang in the search results, both in design and in structure.
I highly recommend reading and using microformats and micro-markup wherever possible. microformats.org
It is important to understand that good document semantics is meaningless if it does not contain necessary and useful information.
The markup also helps when displaying results in Google, for example, if you create a page with reviews, then in the search results you will see stars and their number.

Answer 3

Article, header and footer, that is, the html layout is not affected. If Google can read information, it reads it, regardless of the presence or absence of any html tricks. Another thing is that crooked sites may have problems with page crawling.
An Sem was very right about micro-markup and extended descriptions. More details can be read here .
This is not a guarantee of reaching the first page, but the conditions for the correct understanding of the content of the site by Google.

Answer 4

tags such as header, aside, section or footer were created for seo. By themselves, they have no effect on the markup of the text. You can insert at least 20 headers or asides into the page. They are needed only for logical markup (it's speculative to understand: header - header, aside - sidebar, footer - footer).
