B2B buyers do not need to visit a vendor’s website to form an initial shortlist. They can ask an AI answer engine to explain a category, recommend providers for a specific use case, compare products, or summarize the risks of an implementation. The resulting answer can introduce a company, reinforce a competitor, or omit the brand entirely.
Answer engine optimization tools help marketing teams measure that new discovery layer. They track relevant prompts, brand mentions, competitor share of voice, cited sources, and changes over time. The strongest platforms go a step further and help a team decide which page to improve, which publication to approach, or which positioning gap to address.
The best tool depends on the maturity of the program. This comparison evaluates seven options by the marketing workflow they support, not by a universal feature score.
What is an AEO tool?
An AEO tool measures and improves how a brand appears in AI-generated answers. A typical platform runs or analyzes prompts across products such as ChatGPT, Claude, Gemini, Perplexity, Microsoft Copilot, Google AI Mode, and Google AI Overviews. It then reports some combination of:
- brand visibility or mention rate;
- position or prominence inside an answer;
- competitor share of voice;
- sentiment and narrative;
- cited domains and individual URLs;
- prompt and topic gaps;
- changes by model, market, and time period.
This complements SEO. Traditional search data still explains rankings, links, demand, crawlability, and website traffic. AEO data explains whether a brand becomes part of the synthesized answer and which external evidence shapes that result.

1. Elmo: best open-source AEO tool
Elmo is an open-source, self-hosted AI visibility platform. It tracks custom prompts across AI answer engines, records mentions and citations, benchmarks competitors, calculates share of voice, and shows which domains and pages are newly influencing answers.
Its most important distinction is the operating model. The organization can deploy Elmo on its own infrastructure, retain its prompt and response history, inspect the source code, and audit how metrics are calculated. For B2B companies with technical support, that turns AI visibility data into an owned marketing asset rather than a vendor-controlled report.
The platform is particularly useful for citation strategy. Marketers can move from “our visibility declined” to “these third-party pages appear for our evaluation prompts, and these competitors are cited there.” That creates a defensible content and digital PR backlog.
Elmo has no self-hosted license fee, although infrastructure and answer-collection providers still cost money. It also needs an internal owner for configuration, upgrades, and data operations.
Best fit: technical B2B organizations, privacy-conscious companies, and agencies that value transparency and control.
2. Profound: best for enterprise breadth
Profound combines Answer Engine Insights with prompt-demand data, agent analytics, page analysis, and content or execution workflows. It is designed to connect measurement with a wider enterprise AEO operation.
For a large marketing organization, the benefit is depth across teams. Content strategists can investigate prompts and citations, web teams can examine agent activity, and leadership can monitor competitive visibility. The investment makes sense when the company has people and processes ready to act on those different signals.
Smaller teams should distinguish what they need today from what might be useful later. A broad suite is valuable only when its workflows are adopted.
Best fit: enterprise brands with a funded, cross-functional AEO program.
3. Peec AI: best for a focused marketing workflow
Peec AI structures analysis around visibility, position, sentiment, prompts, competitors, and top sources. Its hosted interface is oriented toward marketing teams and agencies, with recommendations that translate performance data into content and outreach opportunities.
This focus reduces the effort required to establish a recurring reporting process. A team should still evaluate its required engines, regions, run cadence, exports, and client workspace needs before standardizing on it.
Best fit: marketers and agencies that want purpose-built analytics without operating infrastructure.
4. Scrunch: best for connecting monitoring and site action
Scrunch measures presence, position, sentiment, competitors, prompts, and citations, then adds site and agent signals. Its capabilities include AI bot traffic, page-level diagnostics, content gaps, and agent-experience tooling.
That combination helps answer a crucial follow-up question: why is the brand absent? The issue may be missing content, weak third-party authority, an inaccessible page, or a message that AI systems interpret incorrectly. Connecting answer data with site diagnostics can shorten the path from report to intervention.
Best fit: growth and enterprise teams that want hosted analytics tied to technical remediation.
5. Otterly.AI: best for straightforward monitoring
Otterly.AI offers prompt research and monitoring, brand reports, citations, domain rankings, sentiment analysis, competitive views, and exports. Its strength is accessibility: a smaller team can define prompts and begin recurring analysis without a substantial implementation project.
As with any simplified workflow, buyers should confirm that the reporting detail and history are sufficient for their stakeholders. Ease of use is valuable when it increases the likelihood that someone reviews the results and acts every week.
Best fit: small and midsize marketing teams that want a quick start.
6. Semrush: best for unifying SEO and AEO
Semrush includes AI visibility, competitor research, prompt discovery, brand performance, site auditing, and reporting alongside its traditional SEO capabilities. This can connect AEO findings to established content, keyword, backlink, and technical workflows.
The integrated approach is especially attractive when SEO already owns AI visibility. It also makes stakeholder reporting easier because traditional and AI search metrics can share an ecosystem. Teams should understand which reports use a broad prompt database and which repeatedly track their custom prompts; the distinction affects how results should be interpreted.
Best fit: SEO-led organizations that want one search-marketing environment.
7. Ahrefs Brand Radar: best for broad opportunity discovery
Ahrefs Brand Radar draws on a large index of search-backed prompts to reveal brand mentions, competitors, cited sources, and topics across AI answers. It can help a team discover category conversations before it has built a complete custom prompt library.
That broad view pairs naturally with Ahrefs’ existing link and content data. The platform is well suited to researching which third-party domains influence a market. For precise campaign measurement, define and track a stable group of buyer prompts in addition to exploring the index.
Best fit: SEO and content teams that prioritize market-scale source discovery.
How to choose an AEO platform
The evaluation should begin with a workflow, not a demo.
Define the decisions
List the actions the tool is expected to support. Examples include updating an inaccurate comparison page, creating content for a missing use case, pitching an industry list, correcting inconsistent entity information, or proving that a campaign improved share of voice.
Build a buyer-centered prompt library
Include questions across the funnel:
- Problem awareness: “How do I measure whether AI recommends my company?”
- Category education: “What is answer engine optimization?”
- Evaluation: “What are the best AEO tools for B2B SaaS?”
- Comparison: “What are alternatives to Profound?”
- Constraint: “Which AI visibility platform can I self-host?”
- Implementation: “How often should I run AI prompt tracking?”
Avoid creating dozens of trivial wording variants. Coverage across intent, audience, use case, and constraint is more valuable than raw prompt count.
Inspect the evidence behind every metric
Visibility scores are not standardized. Ask how a mention is counted, whether position changes the score, how aliases are handled, and whether the team can inspect the full response. Aggregate metrics are useful for reporting; raw responses are necessary for diagnosis.
Evaluate citations at the page level
A domain-level count can identify an influential publisher, but an individual URL tells the team what to do. The cited page may be a category guide, documentation page, comparison, directory, discussion, or research report. Each requires a different response.
Elmo’s citation page allows this workflow: identify the URLs and domains models cite, examine competitor sources, and turn those gaps into owned-content or outreach priorities.
Compare total operating cost
Include license fees, implementation, model or scraper usage, infrastructure, analyst time, report preparation, and maintenance. Self-hosting reduces vendor dependence but adds operational work. Managed SaaS reduces infrastructure work but places more of the method and history inside a vendor system.
A weekly AEO workflow for B2B teams
A tool creates value only when it supports a repeatable operating rhythm:
- Review the trend, not one answer. Look for changes across prompts and engines.
- Segment by buyer intent. A brand may perform well for educational prompts and disappear from comparisons.
- Inspect winning competitors. Note both their positioning and the sources supporting it.
- Prioritize three actions. Choose one owned-page improvement, one third-party authority opportunity, and one messaging or technical fix.
- Record the intervention. Mark publication and update dates so later changes can be interpreted.
- Report outcomes with evidence. Pair scores with representative prompts, answers, and cited pages.
For teams exploring an open-source workflow, the Elmo live demo shows how prompt, competitor, and citation data can be connected before committing engineering time to a deployment.
Which AEO tool is best?
There is no single winner for every operating model:
- Elmo is the strongest fit when a team wants open-source software, self-hosting, data ownership, and auditable metrics.
- Profound is suited to enterprise programs that can use a broad research and execution suite.
- Peec AI and Otterly.AI provide focused hosted experiences for marketing teams.
- Scrunch stands out when site diagnostics and agent experience are central.
- Semrush and Ahrefs connect AI visibility with mature SEO research ecosystems.
Shortlist two or three options, run the same buyer prompts, and ask each platform to explain the evidence behind its scores. The best AEO tool is the one your team can trust, operate consistently, and convert into better content and stronger third-party authority.
Frequently asked questions
What metrics matter for AI search visibility?
Start with mention rate, share of voice, position or prominence, sentiment, cited domains, cited pages, and performance by prompt and engine. Connect those leading indicators to AI referral traffic and conversions where analytics allow.
How often should B2B brands track AI prompts?
Use a consistent cadence appropriate to the decision cycle and collection budget. Daily data can expose volatility; weekly analysis is often sufficient for content and digital PR decisions. Avoid treating a single generated answer as a trend.
Can a company track AI visibility without enterprise software?
Yes. Small teams can begin manually, use a hosted entry-level tool, or self-host an open-source platform such as Elmo. The right choice depends on technical capacity, desired coverage, and data-control requirements.
Does AEO replace SEO?
No. AEO extends search strategy to generated answers. Strong technical foundations, clear content, credible third-party mentions, and authoritative links remain relevant, while prompt-level monitoring adds a new measurement layer.
