FAQ

Frequently asked questions

Why should I paste HTML instead of a URL?

Pasting HTML allows for a 100% private, local audit that bypasses CORS restrictions and server-side scraping limitations. Your data stays in your browser.

Which tags are most important for SEO?

The Title Tag and H1 Heading are the most important for ranking. The Meta Description is most important for Click-Through Rate (CTR).

What is a Canonical tag?

A canonical tag tells search engines which version of a URL is the 'master' one, preventing duplicate content issues if your site has similar pages.

How do I find my page source code?

Right-click anywhere on your live webpage and select 'View Page Source' (or Ctrl+U / Cmd+U). Copy the entire block of code and paste it here.

What are OG (Open Graph) tags?

OG tags control how your content appears when shared on social media platforms like Facebook, LinkedIn, and Threads. They are vital for social engagement.

What is the ideal title length?

Aim for 50-60 characters. Any longer and it may be truncated (cut off) in search results, hiding your primary message or brand name.

Should I have more than one H1?

SEO best practice is to have exactly one H1 tag per page that matches the primary topic. Use H2s and H3s for subheadings.

Is this tool free for developers?

Yes, our SEO Tag Auditor is 100% free for all developers, marketers, and site owners to audit their code locally.

Is my source code stored on your servers?

No. Your HTML is parsed entirely within your browser. We never see, store, or transmit your private website code.

What is a 'Missing Meta Description' error?

It means your code lacks a <meta name='description'> tag. Without it, Google may show random snippets from your page, which often reduces CTR.

Does it check for duplicate tags?

Yes, our auditor will flag if you have multiple H1 tags or duplicate title/meta definitions within your source code.

Can I use this for locally hosted sites?

Absolutely! Since it uses pasted HTML, you can audit pages from your local development environment before they are even live on the web.
