Low impact · weight 4 · worth up to 1.3 points of the total score
Screen readers and crawlers read headings as an outline. Jumping from H2 straight to H4 implies a missing level, so the outline reports a section that does not exist.
Step heading levels one at a time. If a heading looks wrong at its correct level, change its styling rather than its tag.

Page links to the rest of the site
Internal links are how crawlers reach the rest of the site and how ranking signal flows between pages. A page with none is a dead end that hoards whatever authority it earns.
Structured data parses as JSON
A JSON-LD block with a trailing comma or an unescaped quote is discarded whole. The rich result it was meant to earn silently never appears, and nothing in the page looks broken.
Open Graph tags are present
Open Graph decides what a link to this page looks like when someone shares it on Slack, WhatsApp, LinkedIn, or Facebook. Missing tags turn a share into a bare URL with no image, which measurably costs clicks.
hreflang alternates are absolute URLs
Google requires fully qualified URLs in hreflang annotations. Relative hrefs are ignored without any error, so the language targeting simply never happens and nobody notices.
