Frequently asked questions about Heading Analyzer
Should there be only one H1 tag per page?
SEO best practices recommend using only one H1 tag per page. The H1 represents the page's main topic and provides an important signal to search engines.
Does heading tag order matter for SEO?
Yes, maintaining a logical hierarchy (H1→H2→H3) is important. Skipping levels (e.g., H1 to H3 without H2) makes it harder for search engines to understand content structure.
Can I pick heading tags based on how big the text looks?
No — heading tags mark the document's hierarchy, not its type size. Screen-reader users skim that hierarchy like a table of contents and jump to the section they want, so a scrambled order leaves them lost. Adjust the size with CSS font-size instead and keep the tags matched to meaning, with h3 nested under h2 rather than chosen for looks.
How can I tell whether my headings alone convey the article?
Pull the headings out in order and read only that list. If it reads like a summary of the article, the structure is sound; if it strings together empty words such as "Overview" or "Other", rewrite them. Many readers never read the body straight through — they scan the headings to find the part they need — and AI answer engines follow the same hierarchy when choosing what to quote. Headings therefore need to work as sentences in their own right.
How to get the most out of Heading Analyzer?
Use exactly one H1 per page, then step down through H2 and H3 without skipping a level.
Mark FAQ questions as H2 or H3 so they line up with your FAQPage structured data.
If a heading just needs to look bigger, style it with CSS instead of picking a smaller tag.
