Data as of August 14, 2026. Next scheduled review: September 14, 2026.
What the evidence supports
- RadiusRank changed its offer on August 14 from the one-time article package recorded on August 12 to a monthly validation subscription with no article writing.
- Peec AI had the lowest sampled self-serve monthly entry at $95; Profound listed $99 monthly billed annually for its Starter plan.
- AEO Engine listed managed service from $1,597 monthly, while Trailblazer listed managed Foundations from $3,500 monthly.
- NoGood used custom pricing; a missing public price should not be converted into zero.
- Prompt counts are not directly equivalent when vendors use different engines, markets and collection methods.

Methodology
- Reviewed official vendor pricing or product pages on August 12, 2026.
- Recorded native billing basis, lowest public price, entry prompt limit, engine scope and implementation model.
- Left custom prices blank and did not convert annual commitments into undocumented month-to-month offers.
- Added a separate first-party RadiusRank offer record on August 14 instead of changing the August 12 vendor dataset.
Limitations
- Taxes, discounts, onboarding, overages and negotiated enterprise terms are excluded.
- Feature presence does not measure data quality, support or business outcomes.
- Vendor pages can change after the snapshot date.
Questions
What is the cheapest AEO option?
It depends on the required workflow. RadiusRank's current $79 month-to-month validation subscription, ongoing monitoring platforms and managed services are not equivalent. One RadiusRank month is enough to validate SEO; compare scope, renewal and implementation, not only the headline price.
Why are prompt limits not directly comparable?
Vendors can differ in engines, markets, run frequency, consumer-interface versus API collection and whether one prompt creates multiple observations.
