When a page is set to noindex, the score is capped, so a page Google will not show never looks healthy. Floating audit panel The panel stays above the page while you browse, and you can drag, minimize or refresh it after you navigate. Every Copy button gives clear feedback, and the panel can also open in a full-size tab. Title, description and SERP preview Length is measured in pixels, the way Google truncates results, and a desktop and mobile preview shows how the snippet may appear. Meta descriptions that contain HTML markup are flagged. Indexability SEOProbe reads both the meta robots tag and the X-Robots-Tag HTTP header, so a noindex set on the server is not missed. Status and redirects See the final HTTP status, the final URL and every redirect hop the browser followed, with temporary redirects and loops flagged. Canonical and Link header Canonical URLs declared in the HTML and in the HTTP Link header are compared, and any conflict between them is reported. Tracking parameters from ads and newsletters are ignored, so they do not cause false mismatches. Hreflang Language and region codes, self-reference and x-default are validated, and alternate pages can be checked for return tags. Headings Review the H1–H6 outline and mark headings directly on the page. Images Find images without ALT or title attributes, view thumbnails and locate each image on the page. Links Review internal, external, phone and email links, highlight them on the page and check all of them for broken destinations in one run. HTML vs DOM Compare the raw HTML with the rendered page to find titles, canonicals, headings or content that only appear after JavaScript runs. Technology detection See the CMS, page builder, analytics tools, JavaScript framework and Google Fonts used on the page. AI crawler access See which AI crawlers robots.txt allows or blocks, and whether each block affects AI training, AI search or user-requested visits. Content-Signal declarations are shown when present. Google results tools Open a Google results page and the SERP tab collects organic results with positions, People Also Ask questions, related searches and the sources cited in an AI Overview when one is shown. Copy the data or export it to CSV, XLSX or Google Sheets, with the query, Google domain and date included. Agent readiness (experimental) On request, check whether the site serves Markdown to AI agents and publishes emerging agent discovery files. Keyword density Review 1-, 2-, 3- and 4-word phrase repetition in the page content, with stop-word filtering for English and Serbian. AI writing signals Review heuristic signals of formulaic or AI-like writing in English and Serbian. The result is an estimate, not proof. Accessibility Check HTML language, document title, ALT text, anchor text, form labels, button names, duplicate IDs and heading order. Export Export the page audit or Google results data to XLSX, download tables as CSV, or create a Google Sheets report in your own Google Drive. PRIVACY AND DATA USE SEOProbe has no server of its own. All analysis runs in your browser. To complete some checks, SEOProbe requests files directly from the site you are analyzing, such as robots.txt, sitemaps, HTTP headers, linked pages and alternate language versions. The webRequest permission is used only to observe the main page navigation in your current tab, so the redirect chain can be shown. Requests are never blocked or modified. Google results data is read only from search pages you open yourself. SEOProbe does not run searches on your behalf. Google Sheets export uses Google sign-in only to create the report in your own Drive. SEOProbe does not sell user data and does not use it for advertising. WHO IT IS FOR SEO specialists, web designers, developers, content editors and site owners who want a fast, visual page-level audit.
