// AUDIT COVERAGE
A practical review of the source you control.
The report separates priority actions, warnings and passed checks, then turns the findings into a portable Markdown checklist for your editor or developer.
Heading structure
Count H1–H6 elements, flag a missing or ambiguous primary heading, and identify skipped levels in the document outline.
Link quality
Separate internal and external links, find missing or unsafe destinations, flag generic anchor text and review new-tab protection.
Image accessibility
Find images without an alt attribute so informative images can be described and decorative images can be marked correctly.

- 3Test after publishing
Use a live crawler, Search Console and performance tools to verify HTTP responses, rendering, indexing and Core Web Vitals.
// QUESTIONS
HTML audit FAQ
Does this crawl my live website?
No. It analyses only the HTML you paste into the browser. It does not request your URL or test server responses.
Is my HTML uploaded to Meta3?
No. The audit runs locally in your browser and the pasted source is not submitted to Meta3 Infotech.
Can it guarantee a Google ranking?
No SEO tool can guarantee rankings. This audit helps identify source-level issues that affect clarity, crawlability and accessibility.
Should I paste a page or an article fragment?
A fragment is enough for headings, links and images. Paste the full HTML document to include title, description and canonical checks.
