"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."
"The GEO score is something no other tool offers. With AI search growing, knowing how visible you are to ChatGPT and Perplexity is becoming just as important as Google rankings."
"Finally a free SEO extension that doesn't feel like it was built in 2015. Clean UI, fast data, and the SERP overlay is exactly what I needed for my link prospecting workflow."
"We use this across our whole agency team. The PDF reports alone save us 2–3 hours per client audit. Wish we found it sooner. Zero performance issues with 20+ tabs open."
"The domain age badge on the SERP is something I didn't know I needed until I had it. Instantly tells me if I'm competing with a 15-year-old authority site or a new one I can beat."
"The CMS detection saved me hours of research when scoping a migration project. One glance and I know the tech stack. Combined with speed scores — this extension does the work of 3 tools."
