RankFlow AI - SEO Analyzer & On-Page SEO Checker

Run an on-page SEO audit, get a clear SEO score, and find actionable fixes for metadata, headings, images, and links.

ANALYZE THE PAGE YOU'RE VIEWING RankFlow AI is a privacy-first SEO analyzer and on-page SEO checker for developers, website owners, and SEO professionals. Click Scan current page to review metadata, headings, images, links, canonical and robots directives, JSON-LD presence, and core Open Graph fields. RankFlow AI analyzes only the page you choose. It does not crawl an entire website or monitor browsing in the background. UNDERSTAND YOUR SEO SCORE See a deterministic 0–100 score with an Issue Summary and four explainable sections: Metadata, Content, Structure, and Indexability. Title and Meta Description length checks use the actual page content to apply consistent Latin-heavy, CJK-heavy, mixed-content, or fallback ranges. Interface language never changes the page's scoring profile. START WITH QUICK WINS Quick Wins highlights up to three high-value, practical improvements from the final recommendation list. The order is deterministic, and the full prioritized Recommendations remain available below. Recommendations can include: • A practical Fix • Current and Recommended values for supported length or count checks • Why the issue matters and the detected Evidence • Show on Page for supported Missing Alt and Multiple H1 issues Show on Page re-checks the current DOM, temporarily marks visible targets, and removes the marker automatically after four seconds. It does not change the page's content or save selectors. PREVIEW, VERIFY, AND INSPECT Use the approximate SERP Preview to review how the current URL, Title, and Meta Description may appear together. Search engines can rewrite titles and snippets, so the preview is guidance rather than a guarantee. Passed Checks lists applicable checks that currently pass. Page Facts keeps supported metadata, headings, image, link, canonical, robots, structured data, and Open Graph facts available for inspection. FIX, RESCAN, AND COPY A REPORT After editing the page, scan again to compare the current total score with the previous successful scan of the same tab and URL. The comparison is short-lived session state, not scan history. Copy SEO Report creates a localized plain-text summary from the latest result. The report is copied only after your click and is not uploaded or stored. PRIVATE BY DESIGN Page SEO analysis stays local. RankFlow AI does not upload page URLs, domains, titles, metadata, headings, links, images, target selectors, scan results, exact scores, score changes, recommendations, reports, or Page Facts. Limited anonymous product-interaction events are sent to Mixpanel. They may include Locale, Extension Version, Score Band, recommendation counts, and stable internal Rule ID / Priority values. They do not include page-derived content, exact scores, deltas, or reports. RankFlow AI uses the existing minimum permissions: activeTab, scripting, and storage, plus the scoped Mixpanel host permission. Version 1.1.0 adds no permissions, background service worker, static content script, AI API, or remote executable code. AVAILABLE IN FIVE LANGUAGES Use RankFlow AI in English, 繁體中文, 日本語, 한국어, or Deutsch. UI labels and report templates are localized; page facts remain in their original language. RankFlow AI focuses on fast current-page SEO analysis. It does not provide full-site crawling, backlink data, traffic estimates, keyword volume, rank tracking, page-speed testing, AI-generated metadata, or ranking guarantees.
