No, you paste the HTML, so it also works for pages not yet online.
The on-page basics
Search engines lean on a few basic signals: a descriptive title of about 30–60 characters, a meta description of 70–160, exactly one H1, alt text on images, a canonical link, a viewport tag, a language attribute and enough real content.
This checker looks at those fundamentals. It is a quick audit, not a guarantee of rankings — content quality and links matter too.
