Seventh FeedAI search visibility (GEO/AEO) tools compared: Rank Prompt vs Semrush vs Writesonic vs ChatSEO
Data as of 2026-11-11. Rechecked every quarter.
Traditional rank trackers only check ten blue links on Google. When buyers ask ChatGPT or Perplexity which tool to pick, those rank trackers miss whether the assistant names your brand, links your domain, or cites a competitor’s roundup.
We compared four tools that track AI search visibility (GEO/AEO): Rank Prompt ($49/mo), Semrush ($139.95/mo), Writesonic ($20/mo), and ChatSEO ($29/mo). Rank Prompt focuses specifically on prompt-level citation share across ChatGPT and Perplexity. Semrush tracks Google AI Overviews at scale alongside classic keyword rankings. ChatSEO connects directly to Google Search Console to spot queries where pages rank on page 1 but miss AI citations.
