About this free seo html auditor tool
Inspect pasted HTML for titles, descriptions, H1 headings, canonical tags and missing image alt attributes. Developer utilities inspect or transform data locally rather than contacting the address or service shown in your input. Use fictional samples while checking a format, keep credentials out of shared screenshots and validate the result against the receiving system. Successful parsing does not establish trust, security or schema correctness.
A practical example
A concrete example uses page html source: <html><head><title>Budget Guide</title><meta name="description" content="Plan a monthly budget."><link rel="canonical" href="https://example.com/budget"></head><body><h1>Budget Guide</h1><img src="photo.jpg"></body></html>. The result is a structured output you can inspect in the result field.
Before you rely on the result
Examines pasted source without executing scripts. It is not a live crawl or a ranking score. Missing alt attributes need review; an empty alt value can be correct for decorative images. Multiple H1s are not automatically an SEO error.
