The short answer: which AEO tool fits which B2B SaaS team
For an in-house team that wants prompt-level tracking across several answer engines, dedicated trackers such as Otterly and Peec AI are the most direct starting points, with Profound and AthenaHQ aimed at larger programs. Agencies managing many domains should weigh per-domain pricing and workspace limits first. A budget-constrained founder can start with a low-cost tracker or HubSpot's free AI Search Grader for a one-time baseline, since HubSpot's AEO tools guide describes that grader as a one-time assessment across ChatGPT, Perplexity, and Gemini. No single option wins every profile, and the rest of this page shows where each one earns its place.
| Team profile | Starting point | Why |
|---|---|---|
| Early-stage founder | Otterly | Lowest published entry price among the reviewed tools |
| In-house mid-market team | Peec AI | Prompt-level tracking across engines |
| Large enterprise program | Profound or AthenaHQ | Citation-source attribution and broader monitoring |
| Agency | Rankability | Designed around multi-client reporting |
Pairings reflect published positioning, not a ranking of overall quality.
How the options were chosen, and where bias could enter
How the options were chosen is a five-criteria check applied to every AEO tool. The criteria are engine coverage across ChatGPT, Claude, Perplexity, Gemini and Google AI Overviews; citation attribution to specific URLs; pricing model; integrations with existing reporting; and documented fit for a team profile. Each criterion was checked against vendor documentation or the third-party roundups listed on this page.
However, several of those roundups are written by vendors that also sell AEO products, which creates a conflict of interest this page does not resolve. The page does not claim neutrality on that point. Where a capability is not publicly documented, the page states that gap instead of inferring it. Readers should weigh each claim with the source's commercial interest in mind before relying on it.
Why prompt-level measurement matters more than a single score
A useful AEO tool tracks brand mention rate across a defined prompt portfolio. According to LoudFace's B2B SaaS guide, that portfolio is typically 40 to 75 prompts, and the tool should attribute citations to specific URLs. Rankability takes a different approach, reporting a single 0 to 100 Search Performance Index per keyword. That index blends traditional rankings with AI mentions and citations. A blended score is easy to read. However, it can hide which prompts drive citations.
- Prompt-level data shows which specific prompts produce citations.
- URL-level attribution shows which pages earn answers.
- A blended score summarizes performance but does not explain it.
Teams that need to act on specific pages should therefore prefer prompt-level data.
What each tool does well and where it falls short
Otterly is positioned as the lowest-friction entry point for early-stage B2B teams, according to GEOscanAI's comparison. Peec AI suits teams that want daily prompt tracking, which is how LoudFace says it runs its own tracking. Profound's strength is citation-source attribution for structured content experiments, and it has the largest reported funding in the category. AthenaHQ and Scrunch AI target higher price points. Rankability is built around agency workflows. Limits matter:
- None of these tools
- On the published material reviewed
- Guarantees a citation or measures pipeline directly
- So teams still need their own conversion tracking
Each tool's fit depends on the team's profile, budget and engine coverage needs.
Pricing models and what they cost at scale
Pricing varies by domain, by prompt count and by tier, and the figures below are as listed by sources reviewed, not current quotes. Passionfruit's B2B SaaS guide gives a range of $99 to $2,500 per month across AEO/GEO tracking tools. Other published starting points differ by source:
- Otterly at $29 per month
- Peec AI at €89 per month
- AthenaHQ at $295 per month
- Scrunch AI at $300 or $250 per month depending on the roundup
Per-domain pricing penalizes agencies with many clients, while per-prompt pricing rises as the portfolio grows. Price changes frequently, so verify on each vendor's site before budgeting.
| Tool | Published starting price | Source |
|---|---|---|
| Otterly | $29/month | OutreachBloom, as listed |
| Peec AI | €89/month | OutreachBloom, as listed |
| AthenaHQ | $295/month | OutreachBloom, as listed |
| Scrunch AI | $300 or $250/month | OutreachBloom or Indexly and Passionfruit |
| Rankability | $97/month | Rankability roundup |
Prices reflect each source's listing at review time and are not verified against live vendor pages.
How should a team measure AEO success?
Measuring AEO success means tracking four measures on a fixed prompt set over time. Share of model is how often your domain appears across that prompt set. Citation rate is how often answers link to your URLs.
Mention position is where in the answer your brand appears. Sentiment describes how the brand is characterized. According to Rankability's agency roundup, pages cited across eight or more queries had a 43.3% top-10 AI citation rate, versus 15.5% for pages cited for a single query.
That gap suggests breadth of citation matters as well as depth. Single-prompt snapshots fluctuate, so trends across the fixed prompt set matter more than individual results.
Common mistakes when choosing an AEO tool
The most common error is buying on headline score rather than on prompt coverage and attribution. Teams also underestimate how much monitoring data must be stitched into existing reporting. According to Rankability, most AEO tools leave that stitching to the buyer.
A third mistake is changing prompts midway through a measurement period, which breaks trend lines. Finally, teams often skip the question of whether a tool's findings lead to content changes at all. Monitoring without a content process produces data nobody acts on. Therefore, define the content workflow before choosing the tool.
How to choose: match the tool to your situation
Choosing an AEO tool starts with the team profile, then the budget, then the engine coverage actually needed. An in-house team tracking a few hundred prompts has different needs from an agency serving ten clients. For example, per-domain pricing matters more to agencies. According to Rankability's roundup, most AEO tools were built for in-house teams and often charge per domain, so agencies should check that pricing model closely. Run a 30-day trial on a fixed prompt set before committing. Record citation changes against the pages updated during that period. However, none of these tools solves the underlying content quality question. The choice should therefore follow a clear plan for what to publish and how to measure it.
- Team profile: in-house or agency, and number of domains.
- Budget: confirm current vendor pricing before deciding.
- Engine coverage: list the engines your audience uses.

Frequently asked questions
What is the best AEO tool for B2B SaaS?
No single tool wins every profile. Early-stage founders often start with Otterly, in-house mid-market teams often evaluate Peec AI, and larger programs look at Profound or AthenaHQ. Agencies managing several domains usually compare Rankability on workflow fit. Choose by team profile, budget and the engine coverage you need.
How much do AEO tools cost for B2B SaaS?
**Passionfruit's guide lists AEO and GEO tracking tools at $99 to $2**,500 per month. Published starting prices vary by source. For example, Otterly starts at $29 per month, while AthenaHQ starts at $295 per month. Prices change often. Confirm current pricing on each vendor's site before budgeting.
Which AI engines should an AEO tool track?
A useful tool should cover ChatGPT, Claude, Perplexity, Gemini and Google AI Overviews. LoudFace's guide describes these as the engines a prompt-level tracker should monitor. However, support differs between vendors. Confirm coverage for each engine you care about before purchasing.
What does prompt-level tracking mean?
Prompt-level tracking measures brand mention rate across a defined set of prompts. According to LoudFace, that set is typically 40 to 75 prompts. Prompt-level tracking also attributes citations to specific URLs, which shows which pages earn answers. A blended score can hide these details. Therefore, prompt-level data is more useful for deciding what to change on each page.
Is there a free way to check if AI engines mention my brand?
According to HubSpot's AEO tools guide, HubSpot's free AI Search Grader provides a one-time assessment across ChatGPT, Perplexity and Gemini. It gives a snapshot rather than ongoing monitoring. However, a snapshot cannot show trends over time. For continuous tracking, a paid tool with a fixed prompt set is needed.
Why do agencies struggle with most AEO tools?
According to Rankability's roundup, most AEO tools were built for in-house teams. They often charge per domain, cap workspaces and require stitching monitoring data into a separate reporting tool. Agencies should therefore check per-domain pricing and multi-client reporting before selecting a tool. Those two factors often decide whether a tool fits agency work.
How do I know if an AEO tool is worth the cost?
A tool is worth its cost when citation gains on a fixed prompt set outweigh the price. Set a baseline on that prompt set before buying anything. Then run a 30-day trial and record citation changes against the pages you update. According to Passionfruit, the typical ROI is 4 to 7 times within six months. However, that figure comes from a vendor-authored guide. Validate it against your own conversion data before relying on it.
What is the difference between AEO, GEO and traditional SEO?
Traditional SEO focuses on rankings in classic search results. By contrast, Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO) focus on whether answer engines cite or mention a brand in generated responses. The metrics therefore differ. SEO uses rankings. AEO and GEO use share of model, citation rate and mention position.
