# Vibindex > Vibindex is a free technical SEO auditor for websites built with AI coding tools such as Lovable, Bolt, Cursor, Replit and v0. It crawls a sample of a site's pages, renders them in a headless browser at a phone viewport, and reports evidence-based findings with plain-language explanations and copy-paste fix prompts. Vibindex reports what it observes on public URLs. It does not access Google Search Console, so it never claims a page is indexed or ranking. Scores are Vibindex's own coverage-aware assessment, not Google's ranking factors, and AI content suggestions are labelled separately and never change the score. ## What a scan checks - Crawlability and indexability: HTTP status, HTTPS, redirects, robots.txt, noindex directives, canonical URLs, and XML sitemaps. - JavaScript rendering: differences between the initial HTML and the rendered page (title, description, canonical, robots, content, links), JavaScript exceptions, and failed resources. - On-page SEO: titles, meta descriptions, headings, image alt text, language and viewport tags. - Content quality: repeated blocks and headings, generic headings, off-topic sections, service-page usefulness, and duplication across pages. - Internal linking: broken and redirecting links, anchor text, and links to sitemap pages. - Performance: Lighthouse lab results from Google PageSpeed Insights. - Structured data: whether JSON-LD is present and valid. ## Pages - [Home](https://vibindex.craftnor.com/): Start a scan and learn how Vibindex works. - [Privacy Policy](https://vibindex.craftnor.com/privacy): How scanned URLs and page data are handled. - [Terms of Service](https://vibindex.craftnor.com/terms): Acceptable use, scan limits, and how to interpret results. ## Optional - [Sitemap](https://vibindex.craftnor.com/sitemap.xml): All public pages.
