Enter your URL at the top of this page and click Analyse. RankNibbler will fetch your page and run over 100 checks covering meta tags, headings, images, links, structured data, readability, keyword density, tech stack, accessibility, and more. You will receive a score out of 100 with clear recommendations for every issue found.

over 100 on-page SEO factors per page — title tags, meta descriptions, heading structure, image alt text, links, structured data, Open Graph tags, canonical URLs, robots directives, readability, tech stack and accessibility — and the site audit crawls your whole site to catch these issues on every page at once.

A score of 80 or above is considered good and means the page follows most SEO best practices. A score of 50–79 means there are several issues worth fixing. Below 50 indicates significant problems that are likely hurting your search rankings. See the full score breakdown for details on how each check contributes to the total.

A visually polished website can still have poor on-page SEO. Common hidden issues include missing meta descriptions, duplicate title tags, missing alt text on images, no structured data, and render-blocking scripts. These are invisible to visitors but affect how search engines understand and rank your pages.
