Once search engines can reach and index your pages (the technical roots), the next audit is on-page: the structure and content that decide whether a reachable page is actually understood and worth ranking. This is your site's trunk — and unlike rankings, it's entirely a checklist you control. Here's an on-page SEO audit checklist to run page by page.
Pair it with the technical SEO audit checklist for the full foundation.
1. The H1 — one clear main heading
- Exactly one H1 per page.
- It describes the page's subject the way a customer would search.
- Not vague ("Welcome") or brand-only — it names the actual topic.
2. Heading structure — a logical outline
- Headings form a sensible hierarchy (no skipping H1 → H4).
- If you read only the headings, they summarize the page.
- Headings used for structure, not just visual size.
3. Title tag & meta description — your search-result pitch
- A title that leads with what the searcher wants and isn't truncated.
- A description that sets accurate expectations (no overpromising).
- Each page's title/description is unique, not duplicated across pages.
4. Internal links — connected, not stranded
- The page is linked to from relevant other pages (not an orphan).
- It links out to related pages with descriptive anchor text.
- Important pages are well-linked, not buried. (See internal linking for SEO.)
5. Content — answers the intent
- The page satisfies the search intent, not just mentions the keyword.
- Depth matches the question — thorough without padding.
- It's genuinely useful enough that a reader doesn't bounce back to search.
6. Page-type fit
- The page has what its type needs — a product page needs different things than an about page. See the page-type checklists for the specifics.
Audit every page without doing it by hand
Running this on one page is easy; running it consistently across a whole site is where it breaks down. CommandSEO performs this on-page audit for every page, flags what's missing by severity, drafts the fix, and verifies it shipped. See how it works or the deeper on-page structure piece.
On-page SEO is a checklist, not a gamble. Give every page a clear H1, a logical structure, real internal links, and content that answers the question — and reachable pages become rankable ones.
