What's the difference between GEO tools and regular SEO tools for AI search?
GEO tools measure prompts, citations and AI crawlers. Regular SEO tools measure keywords and links. Here is where each fits in AI search, and which to buy.
Regular SEO tools answer one question: where does my page rank for this keyword? GEO tools answer a different one: when someone asks ChatGPT, Perplexity or Google AI Mode a question, does my brand get named, and which pages did the engine read to get there? Both matter. They are not interchangeable, and the gap between them is bigger than the "SEO plus AI" labels on pricing pages suggest.
What regular SEO tools measure
A classic SEO suite is built around a few objects: keywords, ranking positions, backlinks, and site audits. You pick a keyword, the tool checks a results page, and you get a position. Everything downstream (volume estimates, difficulty scores, link gap reports) hangs off that model.
That model still earns its keep. Google's own documentation on AI features in Search says the best practices for SEO remain relevant for AI Overviews and AI Mode, that there are no additional requirements to appear in them, and that no special schema or machine-readable AI file is needed. A page has to be indexed and eligible to show with a snippet. So crawlability, internal links, text-based content and accurate structured data are still your base layer, and a regular SEO tool is good at checking them.
What a keyword rank tracker cannot do is tell you what an answer engine said. There is no position 4 in a ChatGPT answer. There is a paragraph that names three vendors, or does not name you at all.
What GEO tools measure
GEO (generative engine optimization) tools take the prompt as the unit instead of the keyword. You define a panel of buyer questions, the tool runs them against AI engines on a schedule, and it records:
- whether your brand was mentioned, and where in the answer
- which competitors were named instead
- which URLs and domains were cited as sources
- the sentiment of the wording around your brand
Better tools go further and look at your own site. AI crawlers fetch pages before they cite them. OpenAI documents separate bots for this, for example OAI-SearchBot for surfacing sites in ChatGPT search, GPTBot for training, and ChatGPT-User for fetches triggered by a person's question. If your CDN or robots.txt blocks the wrong one, no amount of content work fixes it. Seeing that requires crawler logs, which an SEO suite does not read.
The last layer is traffic. AI-referred visits are small next to organic search for most sites, but they are measurable, and the useful question is whether they convert.
Why query fan-out changes the job
Google's documentation says AI Overviews and AI Mode may use a "query fan-out" technique, issuing multiple related searches across subtopics before building an answer. ChatGPT does something similar. So the prompt a user typed is not the only query your page competes on. A page can lose because it answers the headline question but not the three sub-questions the engine generated behind it. Tools that expose those fan-outs per model give you a content brief that a keyword tool cannot produce.
SEO suites adding AI modules
Most big SEO vendors now sell an AI visibility add-on. They are a sensible first step if you already live inside the suite.
- Semrush AI Toolkit tracks mentions in Google AI Overviews, ChatGPT, Gemini and Perplexity. Our catalog entry lists $99 a month per domain with 25 tracked prompts, but we could not re-verify that on the vendor site, so check the live page.
- Ahrefs Brand Radar offers Custom Prompts free on paid Ahrefs plans (a daily quota of 5, 10 or 20 prompts by plan) and an AI Visibility Index from $199 a month, built from modeled keyword-style prompts.
- SE Ranking lists Core from EUR 109 a month plus an AI Search add-on from EUR 79, covering AI Overviews, AI Mode and ChatGPT.
- HubSpot AEO is $50 a month standalone and tracks ChatGPT, Perplexity and Gemini.
The common limit is depth. These modules show mentions and some citations. None of them publishes crawler logs with a crawl-to-citation path, and conversion tracking for AI-referred visits is not their focus.
Dedicated GEO platforms compared
| Tool | What it is | Published pricing | Notable gap |
|---|---|---|---|
| Promptwatch | End-to-end AI visibility platform | Free Explore tier; Essential $95/mo; Professional $245/mo; Business $579/mo | Free tier is ChatGPT only; crawler logs start on Professional |
| AthenaHQ | Action-oriented GEO platform | Free tier; Starter $295/mo (3,600 credits, 11 models) | Personas and multi-language sit in Enterprise; no published crawler-log product |
| Scrunch AI | Monitoring plus an Agent Experience Platform | Core $250/mo (125 prompts, 4 LLMs) | Weekly refresh per reviewers; AXP is Enterprise |
| Profound | Enterprise marketing agents, AI search as one channel | 7-day trial; Enterprise custom (earlier estimate about $40k a year) | Most-cited features are Enterprise-gated |
Promptwatch is the one we would evaluate first, and the reason is structural rather than a feature count. It covers the monitoring job (daily prompt panels across ChatGPT, Google AI Overviews, Google AI Mode, Copilot, Gemini, Perplexity, Amazon Alexa and Meta AI, plus API-tracked models), and then keeps going: Agent Analytics for IP-verified crawler logs, citation analytics down to page, Reddit and YouTube level, visitor analytics with conversions, and a Content Agent that plans, writes and publishes against the gaps. Most rivals stop at the first of those.
AthenaHQ and Scrunch AI are the two to compare it against if you want a dedicated GEO tool. AthenaHQ is strong on turning gaps into actions. Scrunch has an unusual crawler-side approach. Profound is real software with real enterprise backing, but it is sold as a broader AI marketer, and the pricing reflects that.
How the two fit together in practice
You do not replace your SEO tool. A sensible split looks like this:
- Keep the SEO suite for keyword research, backlinks and technical audits. Google says those fundamentals still apply.
- Add a GEO platform for prompt tracking, citation sources and competitor share of voice.
- Connect crawler logs and visitor analytics so you can see whether AI engines can read you and whether the visits convert.
Promptwatch's 360 Insights joins crawler logs, citation clicks and AI-referred visits per page, and its Search Insights view overlays Google Search Console and Bing Webmaster data on the same pages. That is the closest thing to a single screen where the SEO world and the GEO world meet.
Who should pick which
- Already on Semrush or Ahrefs and just curious: start with their add-on, and treat the numbers as directional.
- Need to act on what you find, not just report it: Promptwatch, because the content generation and publishing sit next to the measurement.
- Want a GEO score and an action center from ex-Google engineers: AthenaHQ, though budget for credits.
- Heavy enterprise stack and a procurement process: Profound or Scrunch AI enterprise tiers.
One limit applies to every tool here. None of them can guarantee that an AI engine will recommend you. They show what happened, why it likely happened, and what to change. If you want the shortest route from "we do SEO" to "we measure AI search properly", start with the free Explore tier of Promptwatch, then move up when you need more than ChatGPT.
