Since 2009, Roskomnadzor has been controlling the dissemination of information on the Internet. For this purpose in 2012, the agency created a registry of banned sites, which is updated daily.

Roskomnadzor may also block the site for less serious violations, for example, Federal Law 152 «On Personal Data».

The most important tag is h1, the main header that should be putted on top of the page. Do not add more than one tag h1 because the crawler may identify the tag not correctly and drop important information.

Use subheads h2-h6 so much as you want and whenever you want. Proper use of header tags will help stimulate the traffic growth. It is no need to put entire text into the header tags because the search engine can see only the first few words of text. The rest are injected.

The text on the page shouldn’t be too short; otherwise there won’t be a sufficient number of keywords. But it shouldn’t be too long as well. In this case, the article will become "diffused" in the eyes of search engines and keywords will get lost in a long text.
