What It Is
Header tags are the HTML codes that mark headings on a page. The H1 is the main heading, like the title of a chapter. H2s mark the main sections beneath it, and H3s mark smaller points inside those sections, down to H6. They create an outline, just like headings in a well-organized report. In WordPress, you choose the heading level from a menu in the editor.
Why It Matters for Your Business
Headings help people skim, which matters because most visitors scan before they read. They also help search engines understand how a page is organized. An electrician’s service page with an H1 for "Panel Upgrades in Naperville" and H2s for cost, signs you need one and the process is easier to read and easier for Google to understand than one long block of text.
Good to Know
Common mistake: picking heading levels for their size or style. If you want bigger text, change the style, not the heading level. Use one H1 per page that states the topic, keep headings in logical order and write them in the words customers use, not clever slogans.
