Data as of August 14, 2026. Next scheduled review: September 14, 2026.
What the evidence supports
- The two entry offers are not price-equivalent: RadiusRank is a cancel-anytime subscription where one month is enough to validate SEO, while AEO Engine is an ongoing managed program.
- AEO Engine's published Growth and Scale tiers increase prompt and execution capacity, while RadiusRank keeps the product workspace intentionally small.
- Any AEO Engine outcome or guarantee claim on its official site is vendor-stated and was not independently verified by RadiusRank.
Side-by-side scope
Competitor prices and limits were verified on August 12, 2026. RadiusRank's current offer was verified on August 14, 2026.

|---|---|---|
| Entry commitment | $79/month after a three-day diagnostic; cancel anytime | $1,597 monthly Growth plan; 90-day rolling contract |

Methodology
- Reviewed each vendor's official pricing, product or service page on August 12, 2026.
- Normalized delivery model, native billing basis, entry capacity, documented engine scope and implementation responsibility.
- Kept credits, prompts, questions and managed outputs in their native units because they are not directly interchangeable.
- Added RadiusRank's changed offer as a separate August 14 record instead of rewriting the August 12 vendor snapshot.
- Did not treat vendor claims as independently verified outcomes.
Limitations
- AEO Engine contract, overage, onboarding and custom enterprise terms were not tested.
- Pricing, limits and product behavior can change after the snapshot date.
- No identical-prompt accuracy, usability, support or outcome test was completed.
- RadiusRank is the publisher and has a commercial interest in this comparison.
Questions
Is RadiusRank cheaper than AEO Engine?
The public entry price is lower, but the offers are not necessarily equivalent. RadiusRank is $79 per month, cancel anytime, and one month is enough to validate SEO; AEO Engine's documented offer is human-managed aeo program.
Which product has better data?
This review did not run an accuracy benchmark. Ask both vendors to show raw observations for the same questions and disclose the collection method before deciding.
