What is LANGR SEO?
LANGR SEO is a free, online SEO audit tool that scans any website and delivers a complete technical SEO report in under 60 seconds. The tool runs 29 specialized modules with a combined 290 individual checks, covering everything from page speed and accessibility to security, meta tags, structured data, and crawl budget.
Each analysis generates six separate scores: performance, SEO, accessibility, best practices, security, and an overall score. Results include a prioritized list of issues with actionable recommendations, so you know exactly what to fix and in what order. Reports can be shared via link, sent as a PDF by email, or downloaded as JSON data.
LANGR SEO is built for everyone — from small business owners who want to improve their search visibility to SEO consultants and agencies that need fast technical audits of client websites. The tool requires no registration and is completely free to use. For businesses that want ongoing monitoring, we offer paid plans with daily scans, rank tracking, AI-generated fixes, and automatic optimization.
All scans run in real time directly from our servers. We use Lighthouse, Google PageSpeed Insights, and AI-powered analysis to give you the most complete picture of your website's technical health. Results are cached for 24 hours, and you can schedule daily automated scans to track changes over time.
