Tools are rated on: how directly they measure AI citation (not just traditional rankings), which AI engines they cover, ease of setup, and whether the insight they provide is actionable. We're not paid to feature any of these tools.
The 7 best AEO tools in 2026
Use Perplexity at perplexity.ai to manually run your target queries. Note which sources it cites. Run 20 queries per month, track your citation rate in a spreadsheet, and you have a free AEO measurement system that no paid tool can fully replicate. The Pro plan ($20/month) unlocks higher daily limits and access to different model modes, which can be useful for testing how your content performs across different retrieval approaches.
Google Search Console now surfaces data specifically about AI Overview appearances. Under the "Search results" report, filter by "Search type: AI Overview" to see which queries trigger overviews that include your content. This is first-party data direct from Google — it's more reliable than any third-party tool's estimate of your AI visibility. Set up a property for your domain and check it monthly at minimum.
Google's Rich Results Test (search.google.com/test/rich-results) and Schema.org's validator are both free. Paste your page URL or code snippet and verify that your FAQ schema, Article schema, and any other structured data is error-free. AI engines rely on schema to understand exactly what questions your page answers — broken schema silently kills your citation potential. Run every page through this before publishing.
Semrush's AI Overviews and AI Citation tracking features (included in Pro and Guru plans starting at ~$140/month) let you track hundreds of keywords and see when your domain appears in AI-generated answers. Their "Copilot" feature can also identify which competitors are consistently cited on topics where you're absent — useful for prioritizing new content. If you're running AEO at any kind of scale, Semrush is the paid tool to evaluate first.
Ahrefs ($99+/month) shows which of your target keywords trigger Google AI Overviews and whether your site is included. Their Keywords Explorer now flags AI Overview triggers at scale, so you can build a content strategy around questions that are already surfaced in AI results. Their Site Explorer is also the best tool for auditing which high-authority sites could link to you — external links still matter for building the authority that gets you cited.
AlsoAsked (alsoasked.com) visualizes "People Also Ask" questions from Google, organized as a tree showing how questions branch off each other. AnswerThePublic does similar work with a broader visual format. Both have free tiers with limited daily searches. Use these to find every question variant around your topic, then make sure your content answers each one with a dedicated heading and direct answer. This is the fastest way to build comprehensive FAQ coverage.
Screaming Frog (free up to 500 URLs) crawls your entire site and flags issues that would prevent AI engines from properly indexing you: missing canonical tags, disallowed bot paths, broken schema, slow page load indicators, and thin content. It's particularly useful for checking that PerplexityBot, GPTBot, and Google-Extended aren't blocked in your robots.txt. Run a crawl quarterly and fix anything flagged.
The free AEO starter stack
You don't need to spend money to get started. Here's the free stack:
| Tool | What it does for AEO | Time investment |
|---|---|---|
| Perplexity AI | Direct citation checking | 1 hr/month |
| Google Search Console | Google AI Overview data | 30 min/month |
| Rich Results Test | Schema validation per page | 5 min/page |
| AlsoAsked (free tier) | Question research | Per content piece |
| Spreadsheet tracker | Citation rate over time | 15 min/month |
Before investing in paid tools, run 3 months with the free stack and establish your baseline citation rate. Paid tools are most valuable when you have enough data to measure ROI — and when you're managing enough content that manual tracking becomes a bottleneck.
What to measure once your tools are set up
- Citation rate — % of your target queries where your site is cited (Perplexity, Google AI Overviews)
- AI referral traffic — sessions from perplexity.ai, chatgpt.com in Google Analytics
- Featured query count — number of distinct queries where you appear, tracked monthly
- Competitor citation rate — how often your top competitors appear on the queries where you don't
