In SEO, an H-tag (heading tag) is an HTML element used to structure the content of a webpage by defining headings and subheadings. H-tags range from H1 to H6, with H1 being the most important and typically used for the main title of the page. H-tags help search engines understand the hierarchy and relevance of the content on a page, which can impact the page's ranking for relevant keywords.

H-Tags in WordPress

In WordPress, H-tags are automatically applied to the titles and headings (also called subheadings) you create within the content editor. Here's how they work:

  • Post/Page Title: When you enter a title for your post or page, WordPress automatically wraps it in an H1 tag, which is the most important heading tag.
  • Headings in the Content Editor: WordPress provides a dropdown menu in the content editor (both in the Classic Editor and the Block Editor) that allows you to select the appropriate heading level (H2 to H6) for your subheadings. (It's common for people to only use H1-H4.)
  • Classic Editor: In the Classic Editor, you can select the heading level from the “Paragraph” dropdown menu in the toolbar.
  • Block Editor (Gutenberg): In the Block Editor, you can choose the “Heading” block and then select the desired heading level from the block settings sidebar or the dropdown menu within the block itself.
  • Customization: WordPress themes often have built-in styling for H-tags, which determine how they appear on your website. You can further customize the appearance of your H-tags adding custom CSS to your theme's stylesheet or by using a page builder plugin.
  • SEO Impact: Using H-tags appropriately in your WordPress content can help search engines understand the structure and relevance of your content, potentially improving your SEO rankings for targeted keywords.

By default, WordPress takes care of applying H-tags to your titles and headings based on your selections in the content editor, making it easy to create a well-structured and SEO-friendly page.
