"I uninstalled MozBar after using RankSEO for one day. It shows more data, looks better, and doesn't slow Chrome down. The traffic hover is a game-changer."

No. RankSEO is built with performance as a priority. It only activates on Google search pages and websites you browse — it never runs in the background. Data is cached per session so the same domain is never fetched twice.
RankSEO pulls from multiple best-in-class data providers: Moz for Domain/Page Authority and Spam Score, SimilarWeb for traffic and engagement stats, RDAP (WHOIS) for domain age, Google PageSpeed Insights for Core Web Vitals, SEMrush for keyword data, and Wappalyzer for technology fingerprinting.
Never. RankSEO does not collect, store, or transmit your personal browsing data. Metric queries go directly from your browser to the data provider APIs — no proxy server, no analytics, no data harvesting. Your privacy is fully protected.
RankSEO combines what used to require 3–4 extensions into one. It shows Moz metrics like MozBar, plus traffic like SimilarWeb, plus domain age like WHOIS tools, plus page analysis like SEOquake — all in a modern UI that doesn't slow Chrome down. It also adds GEO/AI visibility scoring that no other extension offers.
Yes. RankSEO's toolbar appears on every website you visit — not just Google. You'll see DA, traffic, age, CMS, schema count, and the full SEO audit for any page. SERP badges also work on Bing, DuckDuckGo, and Yahoo search results.
GEO (Generative Engine Optimization) score measures how well a page is optimized for AI search engines like ChatGPT, Perplexity AI, and Google Gemini. It analyzes entity structure, semantic clarity, schema markup quality, and content authority signals that determine if an AI will cite your content in its responses.
