What are header tags?

HTML header tags are used to differentiate the headings (h1) and sub-headings (h2-h6) of a page from the rest of the content. These tags are also known to webmasters as heading tags or simply header tags. The most important heading tag is the h1 tag and least important is the h6 tag.

Hi Friends,
Header tags are nothing but headings in your post. Most commonly used header tags are: H1, H2 and H3. Rests are not frequently used and as per my understanding don't have much value in terms of SEO.

• Use of H1 tags: Title of your post is a H1 tag. A post should have only one title tag as far as SEO is concerned. Using more than One H1 tag is not recommended.
• 
  Use of H2 tags: You can have more than one H2 tag in your post. However don't use your keyword for all H2 headings, instead use the keyword in 1-2 H2 tags and try to have LSI keywords other H2 heading. The post should look natural.
• 
  Use of H3 tags: The usage guidelines are same as mentioned above for H2 tags.
• 
  Use of H4, H5 and H6 tags: Rarely used. As far as I know no extra benefits of using keywords in such tags or headers.

The <header> tag in HTML is used to define the header for a document or a section. The header tag contains information related to the title and heading of the related content. The <header> element is intended to usually contain the section's heading (an h1-h6 element or an <hgroup> element), but this is not required.
