Using H tags effectively will not only improve your Search Engine Optimization (SEO), but also the structure and accessibility of your web content.

H tags are used to denote section titles in your content. <H1> tags are normally used for the title of the content and then lower H tags (such as <H2> and <H3>) are used for sub-headers.

1.  Use H1 to H6.  HTML has six heading elements: <H1> through to <H6>. Use <H1> for your main page heading, then <H2> for sub-headings and so on, where necessary.

2.  Prioritize your content.  Search engines view the <H1> tag as the most important title of the page and then go down to <H2>, <H3> and so on. This means that you should always ensure your <H1> tag contains your most important keywords and that your <H2> tag contains your secondary keywords.

3.  Match your H1 tag to your page title.  It's good practice to have your <H1> tag at the top of your web page and to include the same important search content as your title tab. This highlights to search engines — and potential visitors — exactly what your page is about.

4.  Don't overuse H1 tags.  If <H1> tags are so important, why not add lots of them? Don't risk it. Just use one <H1> tag with your most important content and then use as many <H2> and <H3> tags as you need alongside your content.

5.  Think about your target users.  All good SEO comes from thinking about your users. If you structure your headings to make your text easily readable, you'll automatically make it easy for search engines to spider too.  Remember, users first, SEO second.
