About SEO Source Audit
SEO Source Audit checks a web page's on-page SEO straight from its HTML source. Paste the source, or open a saved .html file, and it reviews the title and meta description, headings, canonical and robots tags, Open Graph and Twitter tags, links, image alt text and structured data, then lists every finding with the code it came from.
Because it reads the source you give it, it also works on pages that are not public yet, such as a staging site or a draft. The audit runs in your browser and the source is never uploaded. Reports can be exported as Excel, Word, CSV or PDF.

Frequently asked questions
How do I get a page's HTML source?
Open the page in your browser, press Ctrl+U (Cmd+Option+U on a Mac) to view the source, select all and copy it, then paste it here.
Does it check the live page?
It checks exactly the source you paste. Content that a page builds with JavaScript after loading will not appear in the source, so audit the rendered HTML if that matters.

No. The audit and every export are produced in your browser.
