Frequently Asked Questions
How many H1 tags should a page have?
One. Each page should have a single H1 that describes the page's main topic. Multiple H1s dilute the main topic signal and can confuse search engines. HTML5 technically allows multiple H1s in sectioning elements, but one H1 is the SEO best practice.
What is proper heading hierarchy?
Headings should follow a logical nesting order: H1 → H2 → H3 → H4. Don't skip levels (e.g., jumping from H2 to H4). Think of it like an outline — subheadings should be nested under their parent headings.
Do headings affect SEO?
Yes. Headings help search engines understand your content structure and hierarchy. Keywords in H1 and H2 tags carry more weight than body text. Proper structure also improves accessibility for screen readers.
