Is one GEO tool enough?

It depends on the situation. For a marketing team that only needs to measure content ROI, a single visibility-monitoring tool is enough. If the site's technical infrastructure (JSON-LD, schema, llms.txt) is shaky, however, monitoring alone won't move the score. The most efficient setup is usually a two-stage stack — an infrastructure tool to harden the base, plus a visibility tracker to measure outcomes.

Are more expensive tools more accurate?

Accuracy and price aren't proportional. Enterprise tools like Profound and AthenaHQ cost more because they cover more tracked prompts, more engines and more multi-market coverage — not because their measurement method is inherently superior. Reasonably-priced tools like Otterly or Peec measure against the same underlying LLM APIs. Measurement accuracy depends far more on prompt design quality and execution cadence than on price.

Can we just use the GEO module on an existing SEO tool like Semrush?

Being able to reuse your existing SEO data is a real advantage. That said, Semrush's AI Visibility Toolkit bills $99 per month per domain on top, with additional per-user and per-location fees. The depth of GEO-specific features like auto-generating JSON-LD or edge-injected schema is shallow versus dedicated tools. It fits marketing teams that want SEO and GEO in one view; if GEO depth is the priority, a dedicated tool is the right call.

How is Villion different from the other tools?

Villion is an integrated platform covering GEO, AEO and SEO in one solution. Where others mostly stop at measuring what's visible or producing a content guide, Villion automates diagnosis, improvement and execution as one flow. Visibility measurement and site-signal hardening live in one tool, so the back-and-forth between marketing, SEO and engineering goes away.

How GEO tools are categorized

Profound · Semrush · Bluedot · Otterly · AthenaHQ · Peec · Villion

AI search visibility tools have flooded the market, and that's actually made selection harder. This piece groups the market into four categories and lays out each tool's strengths and limits using primary sources — answering not “which is best” but “which is right for which situation.”

GEO tools comparison — an editorial illustration of four categories laid out as a quadrant grid

Key takeaways

•GEO tools split into four categories: visibility monitoring, SEO extensions, monitoring + content, and site infrastructure + auto execution.
•Pricing ranges from $29/mo (Otterly) to $5,000+/mo (Profound Enterprise) — a roughly 170x spread. Price scales with tracked prompts and engine coverage, not with measurement accuracy.
•Most tools stop at measurement. Only the fourth category automates changes to the technical infrastructure (JSON-LD, schema).
•Tools tuned to the Korean market (Naver search, domestic e-commerce) include Bluedot Intelligence and Villion. Global tools offer Korean UIs and prompt tracking, but local solutions go deeper on market context.

Why the GEO tools market is splitting

Through late 2024, only a handful of products could honestly be called dedicated GEO SaaS. Profound, Otterly and AthenaHQ shaped the early market, while most marketing teams resorted to manually typing prompts into ChatGPT to see how their brand showed up.

Through 2025 two forces split the market. One was capital — Profound raised another $35M in Series B (cumulative $58.5M), drawing money into the category itself. The other was SEO incumbents arriving: Semrush, Ahrefs and others launched GEO modules, forcing marketing teams to choose between extending existing tools or adopting purpose-built ones.

In Korea, BluedotAI launched Bluedot Intelligence in beta in April 2025 as the first dedicated Korean GEO SaaS, and Villion staked out a fourth, infrastructure-led category — covering GEO, AEO and SEO in one solution and automating the path from measurement to execution.

The result, in 2026, is not a single market. Four different problem statements coexist. Comparing only by price or feature count leads to bad decisions; it's safer to split by category first.

Four categories of GEO tools

A useful way to slice the market is by “which layer of the site does the tool touch?” Each category solves a different problem, so the starting point for tool selection shifts accordingly.

Summary of the four GEO tool categories
Category	Problem solved	Representative tools
1. Visibility monitoring only	Measure what AI says about you	Otterly, Peec
2. SEO tool's GEO extension	Compare SEO and GEO in one view	Semrush AI Toolkit
3. Monitoring + content optimization	Measure + content guides / generation	Profound, AthenaHQ, Bluedot, Goodie, Writesonic
4. Site infrastructure + auto execution	Measure + automatically modify site infrastructure	Villion

1. Visibility monitoring only — Otterly, Peec

These tools don't touch the site. They only measure what AI says. The mechanics are simple: the marketing team defines prompts (“What's the best CRM in Korea?”), and the tool runs them daily against multiple LLMs, tracking how the brand and its competitors show up in the responses.

Otterly.AI

Austria-based. Pricing scales by prompt count, and all tiers receive the same features (6 engines tracked simultaneously, 50+ countries supported per their site). The entry price of $29/mo is the lowest among dedicated GEO tools.

Pricing$29 (15 prompts) / $189 (100) / $489 (400) — 15% off on annual
EnginesChatGPT, Perplexity, Google AIO, Microsoft Copilot (base) + Gemini, AI Mode (add-on)
LimitsNo content generation or schema execution. Pair with a separate tool

Peec AI

Europe-based (Berlin). Multi-brand tracking and sentiment analysis are core strengths. Country and language tracking are included at every tier with no surcharge. MCP and API integrations connect directly to external workflows like Cursor and n8n.

PricingStarter €85 (50 prompts) / Pro €205 (150 prompts) — ~$90 / $220
EnginesChatGPT, Perplexity, Gemini, Copilot, AI Mode, AIO
LimitsEurope-first design; Korean market context is comparatively weak

When it fits

When your site's technical infrastructure (JSON-LD, schema, llms.txt) is already in place and you only need measurement. Or as a secondary tool to cross-validate another GEO platform's data.

2. GEO extension on SEO tools — Semrush AI Visibility Toolkit

A GEO module bolted onto an existing SEO platform. The headline advantage is having GEO data inside the same dashboard you already use for SEO — meaning you can compare SEO traffic decline and AI citation growth on a single screen.

Semrush AI Visibility Toolkit

An add-on module to your existing Semrush subscription. $99/month per domain, with the same $99 surcharge stacking per additional user, location and domain (per Semrush's official knowledge base). Brand Performance reports support 68,000+ location and language options.

Pricing$99/mo/domain + $99 per additional user/location/domain. The Semrush One bundle takes $40/mo off
StrengthCo-analyze SEO keyword + backlink data and GEO visibility in one tool
LimitsShallow GEO-specific depth. No auto JSON-LD generation, schema validation or edge injection. Costs compound fast (e.g., 5 domains + 3 users = ~$792/mo on top)

When it fits

Fits marketing teams already on Semrush who want SEO and GEO data in one view. If GEO depth is a hard requirement, plan to pair it with a category-3 or category-4 tool.

3. Monitoring + content optimization

Profound · AthenaHQ · Bluedot · Goodie · Writesonic

These bundle measurement with content guidance and generation. They answer the question “AI cites us less — what content should we produce next?” The five tools below emphasize different parts of that workflow.

Profound

Founded 2023 and led at Series B by Sequoia for a cumulative $58.5M raised — the category figurehead. Its proprietary Conversation Explorer estimates AI search volume (how often a topic comes up in AI). The product positions enterprise-only, so there is no free trial or self-serve sign-up; every tier starts with a demo and sales contract.

PricingLite $499 / Growth $399 / Enterprise $2,000–$5,000+ (per reviews — official page shown post-demo)
EnginesChatGPT, Claude, Perplexity, Gemini, Copilot, Meta AI, Grok, DeepSeek, AIO (Enterprise)
LimitsHigh price band; 1–3 week onboarding; no self-serve, so unsuitable for quick deployments

AthenaHQ

Y Combinator alum, founded by former Google Search and DeepMind leaders. Strengths include daily tracking of hundreds of thousands of prompts and coverage across 60+ countries and languages. Direct integrations with Google Search Console and Shopify let you compare SEO/AEO performance and attribute revenue.

PricingLite $270/mo (annual) ~ Growth $545 ~ Enterprise $2,000+
StrengthGSC and Shopify integrations, multi-region tracking, content publishing workflow
LimitsEnterprise price band. Comparatively limited Korean market context

Bluedot Intelligence

Released by BluedotAI (CEO Sungkyu Lee) in April 2025 — the first dedicated Korean GEO SaaS, currently in beta. A proprietary BII (BlueDot Intelligence Index) bundles visibility, citation rate and sentiment into one score. After diagnosing content blind spots, the platform auto-generates and publishes complementary content.

PricingPosted via a separate pricing page — contact required
EnginesChatGPT, Perplexity, Gemini (per the official page)
StrengthKorean UI, Korean market context, RAG-based citation probability prediction, content auto-generation
LimitsEngine support for Claude and others undisclosed. First year of beta

Goodie AI

Combines AI visibility monitoring, an AEO Content Writer, automated schema tag suggestions, AI Crawler Analytics (e.g., GPTBot behavior analysis) and an Agentic Commerce Optimizer for product visibility into one tool.

PricingPro $495 (annual) ~ $645 (quarterly) / Team/Enterprise contact for pricing
StrengthSchema tag suggestions, Crawler Analytics, Agentic Commerce features
LimitsNo free or low-cost tier — high entry barrier for small teams

Writesonic GEO

Writesonic, a content-generation AI, layered a GEO module on top. Content authoring and AI visibility measurement run inside one workflow. Low entry pricing makes it easy for content-marketing teams to adopt.

PricingLite $39 (annual) ~ $49 / Standard $99 / Pro $249 / Advanced $499
StrengthCombined content + GEO measurement workflow
LimitsShallower GEO measurement than dedicated monitoring tools (Otterly, Peec); content is the main job, GEO is an add-on

When it fits

Best for organizations with strong content teams who can produce, on a steady cadence, the kind of writing AI will cite. Especially good when you want GEO measurement embedded directly inside the content workflow.

4. Site infrastructure + auto execution — Villion

Where the other categories answer “what's visible?” or “what content to write,” the fourth answers “how do we automatically change the site's technical infrastructure?” AI search weighs structured data (JSON-LD), schema, llms.txt and bot handling alongside content, so the layer of tools that automates that work deserves its own category.

Villion

Villion is an integrated platform covering GEO, AEO and SEO in one solution. From site diagnosis through signal hardening to applying those changes so they show up in AI search, the whole flow is automated in one tool. The biggest difference versus other categories is that measurement and execution live together.

PricingFree diagnosis + paid plans (by site size)
CoverageIntegrated GEO · AEO · SEO. Measurement, improvement and execution in one solution. Content creation via in-house CMS
StrengthRemoves the back-and-forth between marketing, SEO and engineering. Tuned for the Korean market
LimitsRequires a brief site integration step on rollout

Which category should you start with?

There is no “best tool.” The starting point depends on your brand's current state. The four situations below cover the most efficient picks.

Situation 1 — Technical infrastructure is weak (almost no JSON-LD or schema)

Start with category 4 (infrastructure + execution). Measurement on an empty foundation doesn't move the score. Auto-generate and deploy JSON-LD to harden the base, then layer visibility tracking on top.

Situation 2 — Content team is solid, but you're not appearing in AI answers

Look at category 3 (monitoring + content) first. Identify the topics and prompts where competitors are cited and you aren't, then focus on the workflow that fills those gaps with new content.

Situation 3 — You want SEO data and GEO data on the same screen

Evaluate category 2 (GEO extension on SEO tools). Fits marketing teams already on Semrush who don't want to add tools. If GEO depth becomes critical, pair with a category-4 tool.

Situation 4 — Infrastructure and content are both healthy; you just need measurement data

Category 1 (visibility monitoring only) is the most efficient. Start with Otterly at $29 and scale prompt count as needed. To validate the data, you can run Peec in parallel as a secondary measurement tool.

The realistic stack — infrastructure + visibility in two stages

The most common combination in practice is a two-stage stack: harden the base (JSON-LD, schema, llms.txt) with an infrastructure tool, then track outcomes with a visibility tool. The market is structured so no single tool covers every layer well. For example, Villion + Otterly — Villion auto-hardens the infrastructure, and Otterly tracks daily to attribute ROI.
