Do I need exactly one H1 per page?

One clear H1 stating the page's subject remains the clean convention, though rankings survive violations. The real cost of multiple H1s is structural mush: if everything is a headline, nothing outlines the page for readers, crawlers or answer engines.

Do keywords in headings help rankings?

Headings are weighed as structural signals, so describing sections in the audience's language helps. Write headings as the questions and labels people actually search, and stop short of stuffing: a heading that reads like a keyword list signals low quality to everyone reading it.

Header Tags (H1–H6)

Header tags are HTML elements (H1 through H6) that structure a page's content into a hierarchy of headings and subheadings.

They help users scan and help search engines understand how a page is organised. Each page should have a single H1 describing its main topic, with H2s and H3s nesting logically beneath it. Clear structure also makes content easier for AI systems to parse and quote.

Heading structure is an outline, and the test is whether reading only the headings summarises the page. Multiple H1s and skipped levels matter less to rankings than commonly believed, but heading text itself is weighed: a wall of clever section names loses to headings phrased the way the audience asks questions, which is also exactly what answer engines lift as extraction targets. The frequent failure is visual: styling body text to look like headings, which reads fine to people and as flat unstructured prose to everything else.

Example

A pricing guide structured as H1 "Google Ads pricing in Thailand", then H2s "What decides the cost", "Typical budgets by industry", "Agency fees", each with H3s beneath. A reader scans it in five seconds, and an AI answering "how much do Google Ads cost in Thailand" can lift the exact section it needs. The same text as one wall of paragraphs gives both nothing to grab.
