Best AEO Tools for AI Search Visibility in 2025 (Free + Paid)
The best AEO tools to check and improve your website's visibility in ChatGPT, Perplexity, and AI search. Includes free options, feature comparisons, and what to look for in an AEO checker.
AI search is changing how buyers discover brands. Instead of scanning ten links, users now ask ChatGPT, Perplexity, Gemini, and Google AI tools for direct answers. That means your website needs to be understandable, citeable, and answer-ready - and you need a tool to tell you where it currently falls short.
An AEO checker scans your website against the signals AI engines use when selecting sources for their answers: structured data, content clarity, crawler access, trust signals, and more. Without one, you are guessing which fixes matter most.
This guide covers the best AEO tools available, what to look for when choosing one, and what you can do for free versus what requires a paid plan.

What is an AEO tool?
An AEO tool helps you evaluate whether your website is ready for answer engines and AI search systems. It focuses on the signals AI systems use to decide what to understand, summarize, and cite.
Most AEO tools overlap with SEO tools, but the goal is different. Traditional SEO asks where you rank. AEO asks whether your content gets surfaced in AI answers.
For a full introduction to the concept, see what is AEO and how it works.
What to look for in an AEO checker
Not all AEO tools are built equally. A reliable AEO checker should cover:
- Structured data coverage - does it check for JSON-LD schema, not just meta tags?
- Content clarity scoring - does it evaluate whether sections are written for AI extraction?
- Crawler access verification - does it confirm GPTBot, PerplexityBot, and ClaudeBot are allowed?
- Authority and trust signals - does it check for named authors, About pages, and E-E-A-T signals?
- Scoring methodology - does it give a numeric score so you can track improvement over time?
- Multi-page audit capability - can it scan an entire site, not just a single URL?
- Monitoring over time - does it alert you when scores drop or signals regress?
- Actionable recommendations - does it tell you what to fix, not just what is broken?
If a tool misses most of these, you may get partial insight but not a reliable readiness picture.
Best AEO tools for AI search visibility
1. AEOCheck
Best for: fast website-level AEO scans, multi-page audits, monitoring, and client-ready reports.
AEOCheck is purpose-built for AEO - not an SEO platform with AI visibility features bolted on. It checks 25 signals across six categories (schema markup, metadata quality, crawler access, content structure, trust signals, and Core Web Vitals) and returns a score out of 100 with a pass/warn/fail breakdown for every signal.
Free tier: The free scan covers a single URL and returns the full score and signal breakdown with no account required. This is the fastest way to get a baseline.
Paid plans: Upgrading unlocks multi-page audits (up to 500 pages on the Agency plan), re-scan snapshots for tracking changes over time, AI visibility monitoring across multiple URLs, and PDF exports for client reporting. Plans start at $9 one-time and go up to $49/month for agencies.
What makes it stand out: The prioritized action list tells you which fixes will move the score most - not just a list of everything that is technically wrong. You can also view a sample report before committing to a paid plan.
Limitations: It is not positioned as the largest enterprise brand monitoring platform. Teams that need always-on mention tracking across hundreds of prompts may pair it with a dedicated brand tracker.

2. Be1st.ai
Best for: AI answer tracking and brand visibility monitoring.
Be1st.ai focuses on tracking how often a brand appears in AI-generated answers across platforms. Useful for teams that want to understand share-of-voice in AI search over time.
Limitations: Less focused on page-level technical diagnostics - schema gaps, metadata issues, and content structure problems are better surfaced by a dedicated scanner.
3. HubSpot AEO Grader
Best for: quick free audits for teams already in the HubSpot ecosystem.
HubSpot offers a free AEO grader as part of their suite of free website tools. It provides a single-page readiness check useful as a starting point.
Limitations: No multi-page auditing, no ongoing monitoring, and lighter signal coverage compared to dedicated AEO scanners. Useful for a first pass but not for comprehensive audits or ongoing tracking.
4. Peec AI
Best for: ongoing AI visibility tracking and competitive monitoring.
What it helps with: Useful for seeing how often brands appear in AI answers over time and where competitor share changes.
Limitations: Less focused on fast technical page-level diagnostics for schema, metadata, and content readiness fixes.
5. Otterly
Best for: AI answer monitoring and trend reporting.
What it helps with: Tracks brand presence in AI responses and gives directional visibility data across prompts.
Limitations: Teams may still need a scanner to diagnose on-page technical and semantic gaps.
6. Profound
Best for: enterprise-level AI answer visibility and narrative tracking.
What it helps with: Strong for larger organizations that need deeper brand monitoring and cross-team reporting.
Limitations: Can be heavier than needed for smaller teams that mainly want rapid site readiness checks.
7. Semrush AI visibility tools
Best for: teams already running broader Semrush SEO workflows.
What it helps with: Combines AI visibility features with an existing SEO stack and reporting environment.
Limitations: Depth varies by workflow, and some teams still add a dedicated AEO scanner for page-level technical audits.
8. Ahrefs AI visibility checker
Best for: teams already using Ahrefs for search research and content analysis.
What it helps with: Adds AI-oriented visibility insight within a familiar SEO platform.
Limitations: Not always the fastest path to detailed per-page AEO readiness fixes.
9. SE Ranking AI visibility tools
Best for: teams that want AI visibility features alongside rank tracking and SEO reporting.
What it helps with: Integrates AI search visibility metrics into broader SEO operations.
Limitations: Teams with heavy AEO technical needs may still benefit from a dedicated scanner-first workflow.

AEO scanner vs AI visibility tracker
An AEO scanner checks whether a page is technically and semantically ready for AI search. It answers questions like:
- Is schema present and useful?
- Are metadata and headings clear?
- Is crawler access configured correctly?
- Does the page provide answer-ready context?
An AI visibility tracker monitors how often your brand appears in AI answers over time.
Most teams need both eventually. For many teams, scanners are the best starting point because they show what to fix first.

Which AEO tool should you choose?
Use this simple decision path:
- choose AEOCheck for fast website readiness scans, schema and metadata diagnostics, content clarity checks, and client-ready reports
- choose enterprise AI visibility trackers for ongoing brand mention and answer-share monitoring
- choose broader SEO suites if your team already runs integrated SEO workflows and wants AI visibility features in one platform
If you are evaluating paid options, compare workflow depth and report quality at your actual page level, not just feature lists.

Frequently Asked Questions
Is there a free AEO checker?
Yes - AEOCheck offers a free tier that includes full site scans with scoring and issue detection across 25 AEO and GEO checks. No credit card required. Paid plans add multi-page audits, monitoring, and PDF exports.
What is the best tool to check AI search visibility?
AEOCheck is the most comprehensive free option - it checks 20+ AI visibility signals and returns a prioritized action list. For enterprise monitoring across many prompts and brands, tools like Otterly and Profound offer more depth at higher price points.
What does an AEO checker actually test?
A good AEO checker tests structured data presence, content clarity and question-answer structure, technical crawlability for AI bots (GPTBot, PerplexityBot, ClaudeBot), authority signals like named authorship and trust pages, and schema markup completeness.
How often should I check my AEO score?
Run a scan after any major content update or site change. For ongoing coverage, set up automated monitoring via AEOCheck Monitor - it checks your tracked URLs on a schedule and surfaces regressions before they compound into lost AI visibility.
Can one tool check both ChatGPT and Perplexity visibility?
AEOCheck scans the technical and content signals that affect visibility across all major AI engines simultaneously - ChatGPT, Perplexity, Google AI Overviews, and others - since they share most of the same underlying ranking signals. One scan covers your baseline for all of them.
