Recommendations for using headings <h1>...<h6>​

• The <h1> heading is the main heading, it must contain most important keywords. Each page of the site should have it's own unique first-level title. It's not recommended to use more than one <h1> per page.
• The content of the <h1> and <title> tags should not be duplicated.
• Titles shouldn't be too short or long, basically no more than 80 characters.
• Be sure to use keywords in titles, no more than 2-3. At the same time, headlines should be informative and readably for users.
• Stick to a strict order of tags, <h1> should always be followed by <h2> and so on. No level must be skipped, for example <h6> cannot follow <h2>.
• Heading tags can only be used for semantic markup of text on a site page. Do not use them for decorative purposes!
