Topical relevance quietly thins out
The H1 is one of the strongest statements about what a URL is about. Lose it and the page competes for its target queries with one hand tied.
A template that drops the <h1>, a redesign that swaps it for a styled <div>, a translation that overwrites it — the page still renders, and the cost shows up weeks later in lost positions.
Danger severity: you get the alert within the hour, not in tomorrow's digest.
Heading regressions are common after redesigns and theme updates, and invisible from the front end.
The H1 is one of the strongest statements about what a URL is about. Lose it and the page competes for its target queries with one hand tied.
Nothing in a visual QA pass flags a heading that became a styled div. It looks identical on screen and reads as nothing to a crawler.
Search engines tolerate it, but it usually means a template bug — and the page no longer says one clear thing.
Three steps, running every day, on something nobody looks at twice a year.
The first crawl saves the headings you monitor on each URL as it should be. That value is what every later run is compared against.
The heading text is extracted and compared, and Wygard counts how many headings match at that level.
Danger-level findings go out right after the crawl batch. Milder ones wait for the daily digest, so the urgent one stands out.
The stored value is your desired state, not a guess. When a later run differs you get both versions side by side — and if the change was intentional, one click adopts it as the new baseline.
This one reaches you within the hour, because the damage starts before the next digest would arrive. Every test's severity can be overridden per site, so your inbox stays useful.
Pick the frequency and the user agent Wygard should send, switch on JS rendering if your pages need it, and the rest needs no attention.
The H1 check is on by default. Subheading checks are opt-in, so you watch only the ones that carry meaning.
| Test | What it catches | Scope | Severity |
|---|---|---|---|
| H1 — heading | The text changed, no <h1> was found, or more than one was detected. |
URL · Basic | Danger |
| H2+ headings | A subheading at the level you chose changed, disappeared, or appeared more than once. | URL · Basic | Heads-up |
What the checks do, and what they don’t.
H1 by default, and any of h2 to h6 that you enable per URL.
A subheading drift is usually a content or layout decision worth reviewing, not an emergency. The H1 check stays at Danger.
No. The check watches the text and the count at the level you configured.
