Heading tags (H1-H6) are critical for both search engines and users. They define the hierarchical structure of your content and signal what's important.

Search engine understanding: Headings help crawlers understand your content's organization and main topics. Google uses them to generate featured snippets and understand page structure.
Accessibility: Screen readers use heading structure to navigate content. Proper hierarchy ensures all users can understand your page.
User experience: Well-structured headings make content scannable. Users can quickly find what they're looking for.
Keyword relevance: Including keywords in headings reinforces topical relevance to search engines.

One H1 Per Page

Every page should have exactly one H1 tag that describes the main topic. This is typically your page title.

Don't Skip Levels

Go from H1 to H2 to H3 in order. Don't jump from H2 to H4 - this confuses both users and search engines.

Be Descriptive

Headings should clearly describe the content that follows. Avoid vague headings like "Introduction" or "More Info".

Keep Them Concise

Aim for 10-70 characters per heading. Long headings are hard to scan; short ones may lack context.

Technically yes, but it's not recommended for SEO. While HTML5 allows multiple H1s in different sections, Google's John Mueller has confirmed that having one H1 that clearly describes the page content is best practice. Multiple H1s can dilute your main topic signal.

The title tag appears in browser tabs and search results, while the H1 appears on the page itself. They should be related but don't need to be identical. The title tag is more important for SEO rankings, while the H1 helps users confirm they're on the right page.

There's no strict limit, but each H2 should represent a major section of your content. For a typical blog post, 3-8 H2 tags is common. The key is that each H2 should introduce genuinely distinct content, not be used just to break up text.

Yes, when it's natural. Including relevant keywords in headings reinforces your content's topic to search engines. However, don't force keywords - headings should be readable and helpful to users first. Keyword-stuffed headings can hurt more than help.

Heading hierarchy matters more than strict order. Your H1 should come first, but after that, the logical structure is what counts. Going H2 → H3 → H2 → H3 is perfectly fine. What hurts SEO is skipping levels (H2 → H4) or having no clear hierarchy at all.
