Scanline
Scanline is a web-based tool that provides free technical SEO audits and AI Readiness (GEO) scores by analyzing a given URL. It fetches the page server-side to simulate how crawlers and AI bots see it, then parses key signals including titles, headings, alt text, canonical tags, structured data, word count, and link structure. These signals are fed to an LLM with a strict output schema to produce both a classic SEO score and an AI Readiness score that measures how easily AI answer engines like ChatGPT or AI Overviews can read, understand, and quote the page correctly. The tool is available without signup for the first scan, and a free account provides 20 credits (enough for two full audits). Paid plans unlock the complete findings list with severity, category, what's wrong, and step-by-step fixes, plus saved scan history and automated weekly health checks depending on the plan. Scanline targets freelancers pitching clients, developers checking staging URLs before launch, and site owners monitoring ongoing health. Its four-stage pipeline (Fetch, Parse, Analyze, Score) is designed to be simple and consistent, with no crawlers to configure or dashboards to learn.
