When designing new web pages you can use Heading Tags to label your headlines. These tags are used to differentiate the headings of a page from the rest of your content. These are often referred to as HTML header tags, and/or SEO header tags. Search engines still consider the contents of these tags as important, especially the H1 tag, which is the first-level heading tag. While the H1 tag is the most important, the least important is the H6 tag. In HTML coding the heading tags from h1 to h6 form a top-down hierarchy.
The Advantages of Heading Tags
The heading tag is used to represent different sections of web page content. It has an impact on both the Search Engine Optimization (SEO) and usability of your site. Search engines use your headings to index the structure and content of your web pages. As you probably do yourself, most users will simply skim your pages by their headings. It is important to use headings to show the document structure.
How to Use Heading Tags
Always include your most important keywords and key phrases within the first-level heading: <H1>Your first-level heading with keywords</H1>
Use only one <H1> tag on any page. In most cases, the top-level heading will be the same as the TITLE, (which by the way is still more relevant to search engines than even heading tags.) The first order, H1 headings should be your primary headings, followed by H2 headings, H3, and so on. Always use them on a page in order to structure information in the proper way but also to avoid penalties that come with skipping around.
Things NOT to Do with Heading Tags
Don’t stuff them with keywords!
Don’t use more than one H1 tag per page.
Don’t use heading tags out of order, like an H1 and a couple H3 tags without the H2.
Don’t repeat the same heading tags on multiple pages.
Don’t set your Title tag different from your H1 tag. Make sure they are consistent.
