Frequently asked questions

What does the Meta Tag Checker check?

It fetches the raw HTML of your page and checks the title tag, meta description, robots/noindex, canonical URL, H1 headings, viewport, language attribute, Open Graph tags, image alt text, structured data, and how much content is visible without JavaScript.

How is the SEO score calculated?

Each check is weighted by its impact. Passing earns full points, a warning earns half, and a failure earns none. Indexability, title and description carry the most weight.

Why does my JavaScript site show very few words?

The checker reads the HTML your server sends, like most crawlers do. If your content only appears after JavaScript runs, search engines may index it late and many AI crawlers won't see it at all. Prerendering or server-side rendering fixes this.

Is it really free?
