Lumina – SEO & GEO

SEO and AI-search checks for the page you're on: meta tags, schema, robots.txt, AI crawlers, tech stack. Free, no account.

Lumina checks the page you're on, right where you are. That includes pages behind a login and staging sites that public web tools can't reach. The first screen gives a verdict for every area at a glance. One click opens the details. What you see for the current tab: - Title, description and canonical, the robots directives, and the status code with the redirect chain your browser actually followed - A SERP preview measured in pixels for desktop and mobile, with AI rewrites of title and description judged the same way - GEO readiness on the raw HTML that AI crawlers read, with a score per answer engine - Query fan-out coverage: which sub-questions behind a keyword this URL actually answers - Which of 37 crawlers robots.txt lets in, from Googlebot to GPTBot, plus a live check of what the server really returns to each - Structured data checked against the required and recommended fields Google documents - The tech stack from 655 signatures, with versions and a flag for outdated ones - Headings, semantic HTML, the share preview with its Open Graph tags, and PageSpeed results - Images with alt text, weight and format, and internal and external links, outlined in place on request - What Googlebot, Bingbot, GPTBot or another crawler gets from this address, with an extra header for staging if you need one - Search Console and Analytics numbers for this URL, with URL Inspection and the traffic ChatGPT, Perplexity and other chat assistants send, once you connect your accounts Quick checks for one keyword: volume and difficulty, and where this URL ranks in Google's top 20, including whether the AI Overview cites the site. Ask AI answers questions about the page with its content, Search Console data and the live results at hand. In Google's results, every organic result shows its position and your own domains stand out. One click gives the search's volume, difficulty and CPC, with related searches. You can switch that bar off. Open it in Chrome's side panel if you like: it stays open while you click through the site and follows your tab. The popup stays the default. Bigger jobs, like full keyword research or a complete SERP analysis, open on lumina-seo.com with this page and its keywords already filled in. Where nothing else is needed, they start right away. In English and German: the interface follows Chrome's language, or the one you pick in Settings. Free, no account. The features that call outside services run on free daily credits. Your own OpenAI, DataForSEO or PageSpeed key lifts the limit, and keys stay in your browser. Made by Julien El-Bahy. The web tools behind it: https://lumina-seo.com/tools/
