If you don’t come from a web design background, you may find some of the terms and phrases used in Blocs confusing. A common point of confusion is surrounding text heading levels and why there are 6 different levels to choose from.

The reason for this is simple, search engines such as Google use the headings to index the structure and content of your web pages. Level 1 headings should be used for main headings on your page (usually found at the top of your page), followed by level 2 sub-headings, then the less important level 3 headings are used throughout further down your page, and so on.

The lower the heading level the more important search engines treat them and the key words they contain.
