Questions
What does the on-page SEO checker look at?
15 checks: HTTPS, response status, title, meta description, H1, subheadings, word count, canonical, noindex, mobile viewport, language, image alt text, internal links, Open Graph tags and structured data.
Is a 100 score guaranteed to rank?
No. On-page SEO is one part of ranking — content quality, search intent and backlinks matter too. The score shows whether the basics are in place.
Can it check pages behind a login?
No. It only sees what a public visitor (and Google) sees.
Why couldn't it open my page?
The site may block automated requests, take longer than 15 seconds, or the URL may be private or invalid.
