Common questions
What is on-page seo?
Everything on the page itself that affects rankings: titles, descriptions, headings, URLs, images and structure.
Is the on-page seo checker free?
Yes. Check any public page with no account and nothing to install.
How many H1 headings should a page have?
One. A single H1 keeps the topic clear; extra H1s are flagged as a warning.
Do urls affect on-page seo?
Yes. Short, readable URLs with the topic up front are easier to crawl, share and trust.
Why check the viewport tag?
It tells mobile browsers how to scale the page; without it the layout breaks on phones.
