Most traditional SEO platforms are still catching up to how LLMs handle brand citations. Odyssey Advance gives us genuine insight into how our clients are cited across ChatGPT, Perplexity, and Claude. Being able to benchmark AI visibility alongside traditional Google rankings has given us a massive edge when pitching to prospective clients.

When migrating our e-commerce store, we were terrified of losing organic search traffic due to indexation drops or broken redirect chains. Odyssey’s Indexation Checker and technical site auditor flagged several canonical tag mismatches before they could impact our revenue. It’s given our in-house team complete peace of mind.
