Skipped heading level

Headings chosen for their size rather than their level — an H4 because it looks right — or widgets and sidebars with their own heading levels.

• Use the levels in order: H2 under the H1, H3 under an H2.
• If a heading was picked for its size, keep the level the outline needs and change its size with CSS.
• Headings in sidebars and footers ("Newsletter", "Contact") rarely need to be headings at all; plain bold text does the job without breaking the outline.

Use a heading outline browser extension, or search the source for <h2, <h3 and <h4 and check they appear in order.

Notice The structure jumps from H1 to H3. · /product/*

The product template uses H3 for its first section; changing it to H2 fixes the outline on every product. (An example shop; the numbers are illustrative.)

ONPAGE-008 is a notice in the on-page category, and weighs lightly in that category’s score. When it appears on many pages built from the same template, the report shows it once, with the number of pages it covers — because one change in the template fixes all of them.

If the finding is deliberate on your site, it can be accepted as intentional in the report. It then leaves the list and the score, and comes back on its own if what it shows changes.
