Q: Why do I need to paste my page source?

Browsers block one website from reading another, so a purely in-browser tool cannot fetch your URL. Pasting source keeps your data private because nothing leaves your device.

Q: What is a good title tag length?

About 30 to 60 characters so it is unlikely to be truncated in Google results.

Q: What is a good meta description length?

About 70 to 160 characters. It does not directly affect ranking but strongly affects click-through rate.

Paste your page's HTML and get an instant SEO score with plain-English fixes. Nothing leaves your browser.

What the audit looks at

1Title & meta description

The title is your headline in Google. Keep it 30–60 characters with the focus keyword near the front. The meta description is your ad copy: 70–160 characters, a benefit and a reason to click.

2Headings

Use exactly one H1 that matches the page's main topic, then H2 and H3 in order without skipping levels. Headings help both readers and search engines understand structure.

3Canonical, robots & viewport

A canonical tag tells Google which URL is the master copy. A stray noindex will remove a page from search. The viewport tag is required for mobile-friendly pages.

4Structured data & social tags

JSON-LD schema can unlock rich results such as FAQs and ratings. Open Graph and Twitter tags control how links look when shared.

5Images & links

Every meaningful image needs descriptive alt text. Links need readable anchor text, and each page should link to related pages on your own site.
