Free SEO HTML Audit: Titles, Canonicals and Indexing Directives
Inspect actual page markup for on-page SEO signals. Review title tags, canonical URLs, robots metadata and headings without an invented health score.
Published by AuditWeb
A free SEO HTML audit checks how a supplied document declares its topic, preferred URL and indexing instructions. It can identify markup to investigate. It cannot confirm how Google has indexed the live page or determine why a query changed position.
Start with the Page Source
The free HTML checker examines eight groups of signals in supplied markup. It checks titles and descriptions, canonical links, robots metadata, H1 elements, image alt attributes, viewport metadata and social image metadata. The result is a source review, not a full SEO audit.
Open the free HTML SEO checker to inspect your page source.
Interpret the Findings in Context
A missing canonical deserves investigation but does not prove that Google selected the wrong URL. A noindex directive can be deliberate. A title character count does not prove how a search result will display. Use the observation to choose a follow-up check.
- Title: compare the text with the page's actual purpose. Google may choose a different title link.
- Canonical: check whether the target is the intended equivalent page. A declaration is a signal, not proof of Google's selection.
- Robots: compare the HTML directive with response headers and the intended index state. A pasted source check does not read those headers.
Use Google's canonical guidance and URL Inspection documentation for the corresponding live checks.
Complete the SEO Review
Confirm important URLs in Search Console. Inspect live response headers and crawl paths. Review content intent and internal linking. Test customer journeys. Combine these evidence sources before commissioning changes or making claims about expected search performance.
Use the editable agency toolkit to record evidence and implementation steps. The 50-check PDF covers a wider manual review.
Our documented self-audit provides real examples of observations and corrections. Review the professional audit scope if the problem requires evidence beyond your page source.
