RankCaster vs HubSpot AI Search Grader
HubSpot's AEO Grader is a free one-shot score — enter a URL, get a reading. It's a great way to prove to a prospect that AI visibility exists. RankCaster is the production platform you move to once the problem is proven: ongoing tracking, 10× cross-validation, publishing loop, MCP and traffic attribution.
