The $7.3 Billion Market You're Not Tracking

The Generative Engine Optimization (GEO) market was valued at $886 million in 2024 and is projected to reach $7.3 billion by 2031, growing at a 34% CAGR—nearly three times faster than traditional SEO tools (Omnius GEO Industry Report).

This explosive growth reflects a fundamental shift in how consumers discover brands:

Metric	2024	2025	Source
Consumers using AI for product research	25%	58%	McKinsey
ChatGPT weekly active users	200M	400M+	Reuters
AI traffic to US retail sites (YoY)	Baseline	+1,100%	Adobe
Queries triggering AI Overviews	6.49%	13.14%	Semrush
Brands systematically tracking AI search	—	16%	Backlinko

Yet despite AI search growing 800%+ year-over-year, only 16% of brands systematically track their AI visibility. That creates a massive opportunity—and a looming threat for companies that don't adapt.

Gartner's Projection: Traditional search traffic will decline by 25% by 2026 and 50% by 2028 as consumers shift to AI-powered discovery.

AI Visibility Checker Tools: The Complete Landscape

The AI visibility monitoring space has exploded since 2024, with over 200 tools now available (LLMrefs AI SEO Tools List). The terminology is still evolving—you'll see these tools called:

• GEO (Generative Engine Optimization) tools

• AEO (Answer Engine Optimization) platforms

• LLM tracking/monitoring software

• AI visibility or AI search tools

Regardless of what they're called, these tools solve the same problem: showing you where your brand appears (and doesn't appear) when users query AI platforms.

Categories of AI Visibility Tools

Category	Description	Examples
Browser Extensions	Lightweight checkers you run on-demand	Adobe LLM Optimizer, Teun.ai, Ekamoira
Free Web Tools	Unlimited or generous free tiers	HubSpot AEO Grader, Semrush Free Checker
SaaS Platforms	Full-featured paid subscriptions	Profound, Peec AI, Otterly.AI, Nightwatch
Enterprise Solutions	Custom pricing, advanced integrations	Adobe LLM Optimizer (full), Semrush Enterprise

Chrome Extension Comparison: Adobe vs Teun.ai vs Ekamoira

Only three significant Chrome extensions exist for AI visibility checking. Here's how they compare:

Feature-by-Feature Comparison

Feature	Adobe LLM Optimizer	Teun.ai	Ekamoira
Price	Free	Free tier (2 scans/month)	Free (1 check/day)
Platforms Checked	Website crawl view only	ChatGPT only	Google AI + ChatGPT + Perplexity + Google AI Overviews
What It Measures	Citation readability score	ChatGPT brand mentions	Full visibility across 4 AI platforms
Custom Prompts	No	Limited presets	Yes (5 editable)
Competitor Detection	No	Yes (in dashboard)	Yes
Brand Monitoring	Single page analysis	Commercial prompts	Any domain
Results Persistence	No	Via dashboard	Yes (resume on reopen)
Account Integration	Adobe Experience Manager	Teun.ai dashboard	Ekamoira API key for unlimited
Best For	Website technical audit	ChatGPT-specific tracking	Multi-platform quick checks

Adobe LLM Optimizer Chrome Extension

Adobe's free extension (Chrome Web Store) takes a different approach from other tools. Rather than querying AI platforms directly, it analyzes how AI crawlers see your webpage.

What it does:

• Measures "citation readability score" for any webpage

• Compares what AI agents see vs what humans see

• Identifies content gaps that prevent AI systems from citing your pages

• Reveals machine-readability issues with your content

What it doesn't do:

• Query ChatGPT, Perplexity, or other AI platforms directly

• Show where your brand appears in AI responses

• Track competitors' AI visibility

• Monitor brand mentions or sentiment

Adobe's Own Results: Using LLM Optimizer, Adobe increased citations for Adobe Firefly by 5x and saw 200% increase in LLM visibility for Adobe Acrobat. (Adobe Blog)

Verdict: Adobe's extension is a technical audit tool for content optimization, not a brand visibility checker. Use it alongside an actual visibility tracker.

Teun.ai ChatGPT Visibility Scanner

Teun.ai's extension focuses exclusively on ChatGPT visibility, making it valuable for teams specifically optimizing for OpenAI's platform.

Strengths:

• Automatic scanning of commercial prompts

• Historical data tracking via integrated dashboard

• Competitor analysis capabilities

• GDPR-compliant with local credential storage

Limitations:

• ChatGPT only (no Google AI, Perplexity, Claude, or Gemini)

• Free tier limited to 2 scans/month with 10 prompts per scan

• No custom prompt editing in the extension

Verdict: Excellent for ChatGPT-specific monitoring, but limited multi-platform coverage means you'll need additional tools.

Ekamoira AI Visibility Checker

The Ekamoira extension is the only Chrome extension offering multi-platform visibility checking with customizable prompts.

Unique Features:

• 4 platforms in one check: Google AI Overviews + ChatGPT + Perplexity + Google AI Mode

• 5 editable prompts: Test "best CRM for real estate" vs "top CRM software" to see different results

• Persistent loading state: Close the extension mid-check and resume later

• Competitor detection: See which competitors appear when you don't

• Email reports: Get results delivered to your inbox

• Upgrade path: Connect Ekamoira API key for unlimited checks

How it works:

1. Install from Chrome Web Store

2. Enter email to activate (no credit card)

3. Enter domain and customize up to 5 prompts

4. Run check (~30 seconds)

5. See visibility scores across all platforms

Limitations:

• 1 check per day for free users

• Requires email signup (lead magnet model)

Verdict: Best choice for marketers who need multi-platform visibility in a single tool and want to customize their search queries.

FAQs

Q: Do I need multiple AI visibility tools? A: For most teams, one comprehensive tool (like Semrush or Profound) plus the Ekamoira extension for quick checks is sufficient. Enterprise brands may want specialized tools for different use cases.

Q: How often should I check AI visibility? A: Weekly tracking is enough for trend monitoring. Daily checks help when actively optimizing content. The Ekamoira extension's 1/day limit aligns with typical optimization cycles.

Q: Why don't traditional SEO tools cover AI visibility? A: Different data sources and APIs. Traditional tools query Google's search index; AI visibility tools must query each AI platform separately. Tools like Nightwatch are bridging this gap.

Q: Is AI visibility more important than traditional SEO? A: Not yet, but it's growing fast. With AI traffic up 1,100% YoY and Gartner predicting 50% less traditional search by 2028, both matter. The best strategy optimizes for both.

Q: What's the difference between GEO, AEO, and LLMO? A: They describe the same practice with different emphasis:

• GEO (Generative Engine Optimization): Optimizing for AI-generated responses

• AEO (Answer Engine Optimization): Optimizing for answer boxes and AI answers

• LLMO (Large Language Model Optimization): Optimizing specifically for LLMs like ChatGPT
