AEOprobe vs Semrush
Which AEO tool fits your workflow? Feature-by-feature breakdown for 2026.
Overview
AEOprobe is a free technical AEO auditing tool that checks your website across 9 categories — AI bot access, structured data, content quality, meta tags, Open Graph, sitemaps, performance, security, and accessibility. It tests 14 AI crawlers against your live robots.txt, validates structured data, and delivers an A+ to F score in 60 seconds. No one else does technical AEO auditing — most tools focus on tracking mentions and citations.
Semrush semrush is a comprehensive SEO and digital marketing suite that added AEO capabilities through its Share of Voice add-on. Originally built for keyword tracking, backlink analysis, and competitive research, Semrush now offers AI search monitoring as an extension to its core platform. The AEO features layer on top of the existing toolkit, requiring an active Semrush subscription plus the add-on fee.
Feature Comparison
| Feature | AEOprobe | Semrush |
|---|---|---|
| AEO Technical Auditing | ||
| AI bot access analysis (robots.txt) | Checks 14 AI crawlers against live robots.txt rules with specific allow/block status per bot | No dedicated AI bot access analysis — site audit covers general crawlability but does not check GPTBot, ClaudeBot, or other AI-specific user agents |
| Structured data validation | Validates JSON-LD, Microdata, and RDFa schemas with field-level error reporting and AEO-specific schema recommendations | Basic structured data checks in site audit — flags missing schemas but does not recommend AEO-specific structured data or validate for AI readability |
| AI Bot Access Analysis | ||
| Number of AI bots checked | 14 AI crawlers including GPTBot, ClaudeBot, PerplexityBot, Google-Extended, Bytespider, AppleBot-Extended, Meta-ExternalAgent, and more | Monitors visibility in ChatGPT, Perplexity, and Google AI Overviews but does not check whether your site actually allows these bots to crawl |
| Content Quality Analysis | ||
| Answer-first content scoring | Evaluates content structure for answer-first paragraphs, conciseness, and AI extractability with specific improvement suggestions | Content optimization focuses on keyword density, readability, and SEO writing assistant — not structured for AI answer extraction |
| AI Citation Tracking | ||
| Brand mention monitoring in AI | Not a tracking tool — focuses on fixing the technical foundations so your site becomes citable by AI engines | Share of Voice add-on tracks brand mentions across AI platforms with trend data and competitor comparison |
| Pricing/Value | ||
| Cost for AEO capabilities | Free tier available with full 9-category audit. No subscription required to get started | Minimum $238.95/mo ($139.95 base + $99 add-on) for any AEO visibility. Annual commitment reduces cost but still $2,800+/year minimum |
| Ease of Use | ||

The Verdict
Semrush and AEOprobe solve different problems in the AEO space. Semrush is a monitoring tool — it tells you where your brand appears in AI-generated answers and tracks that visibility over time. AEOprobe is a diagnostic tool — it tells you why AI engines can or cannot cite your content and gives you a technical fix list.
If you already pay for Semrush and want to add AI mention tracking to your existing SEO workflow, the Share of Voice add-on is a natural extension. But if you need to understand whether your robots.txt blocks GPTBot, whether your structured data is AI-readable, or why your content is not being cited — Semrush does not diagnose those issues.
For most sites, the right approach is to run AEOprobe first to fix the technical foundations (for free), then consider Semrush's add-on later to track your AI visibility once you have something worth tracking.
Common Questions
Does Semrush check if AI bots can crawl my site?
No. Semrush's site audit checks general crawlability but does not specifically analyze whether AI crawlers like GPTBot, ClaudeBot, or PerplexityBot are allowed or blocked in your robots.txt. AEOprobe checks 14 AI-specific crawlers against your live robots.txt rules.
Can I use AEOprobe and Semrush together?
Yes, and this is actually the recommended approach. Use AEOprobe to audit and fix your technical AEO foundations — bot access, structured data, content structure — then use Semrush's Share of Voice add-on to monitor how your AI visibility improves over time.
Is Semrush's AEO add-on worth the extra cost?
It depends on your needs. If you want ongoing tracking of where your brand appears in AI answers alongside your existing SEO data, the add-on provides that. But if you need to diagnose and fix why AI engines are not citing your content, AEOprobe provides that for free.
Which tool is better for agencies managing multiple clients?
Semrush offers project-based management ideal for agencies tracking many clients' AI visibility over time. AEOprobe is better for the initial technical audit phase — running quick assessments to identify which clients have AEO issues that need fixing before monitoring makes sense.
