BUYER’S GUIDE
How to choose an AI seo tool
Pricing per active user, not per seatVendor sites often show seat pricing, which understates real cost when seats sit unused. Multiply by your active-user count.
Agent vs assistantAn agent plans and runs multi-step tasks; an assistant answers one prompt at a time. None of these seo tools ship an agent yet.
Free-tier limits and card requirementsSome “free” tiers ask for a card and bill you past a soft limit. Test the free tier without a card on file.
Changelog and update cadenceAI tools age fast. A vendor that hasn't shipped meaningfully in 6 months is usually about to be lapped.
