score your page for search + ai answer engines
seo·check fetches the page you point it at (html, robots.txt, llms.txt, and your sitemap) and returns one overall score plus three category scores: on-page seo, geo, and sitemap. each breaks into individual checks marked pass, warn, or fail.
seo·checkGEO is the new half of the audit: as Google's AI Overviews, ChatGPT, and Perplexity start answering instead of linking, seo·check checks the things that get a page quoted. that means clean structured data, an llms.txt, answer-shaped headings, and crawlable content. Every failing check comes with a plain-language reason and the fix. Free, no account, and nothing about your site is stored.
