A clear H1 is not a magic ranking factor, but a good structure and template signal: users and crawlers recognize faster what a URL is about.
Just one H1: 58 % (Average of domain values) from 68,464 evaluable domain values in the selected segment. The number describes the sample examined, not all websites or all URLs of these domains.
It is measured whether the retrieved HTML contains exactly one H1 element. The metric does not evaluate the text, its visibility or the entire heading hierarchy.
Problems often do not arise editorially, but in the template: logos as H1, several module headings, missing product names or hero components without a semantic heading.
The benchmark shows whether the website is behind comparable pages with a basic document structure. In the audit, it also counts which URLs are affected.
The benchmark alone does not yet say which measure should be implemented first. In the website audit, the value is combined with URL type, severity, priority and specific findings.
Compare your own domainh1_single is 1 for exactly one H1 element, otherwise 0. Missing and several H1 are combined in this single characteristic number.
A logo and item name are both labeled H1. The value is 0, although a matching article heading exists; the cause may lie in the common layout.
Check main content, visible heading and subsequent H2/H3. A single, but empty H1 is not only therefore a good headline.
Several H1s are not automatic proof of a ranking loss. Subsequently JavaScript-generated headings are not reliably mapped by the pure HTML evaluation.
A benchmark is a benchmark, not an absolute truth. Important is the deviation to the own website and the question of whether the signal for the affected pages is business relevant.
The baseline takes numerical metrics from the latest stored crawl per domain into account, if this was successful. Missing values do not enter as 0. Segments are only calculated from five available domain values. The selection is not a random sample and not a representative market share.
The current sampler selects up to ten URLs from sitemap or internal links; successful retrievals are combined into a domain mean for each metric. Older data sets can be based on a single page. In the case of shares, the page shows the mean value of the domain values, in the case of ALT coverage their median. Not all URLs of a website are examined.
Canonicals are a quiet but important indexing signal: they help search engines merge variants of a page cleanly.
SnippetsMeta descriptions are not a direct ranking lever, but they do influence how convincing a page is in the search result.
Structured dataStructured data makes content more explicit: organization, website, breadcrumbs, articles, products or local company data become easier to read for machines.
