"Finally, a tool that connects the dots between technical SEO and brand visibility in AI. The GEO audit showed us exactly why we were being ignored by Perplexity."

Sarah K., SEO Strategist · June 2026

"The free llms.txt generator is worth its weight in gold. We had a clean, crawlable file ready in minutes, giving us more control over how AI sees our brand facts."

David L., Content Marketing Manager · June 2026

"It's a powerful diagnostic tool, but the monitoring isn't fully automated. We still need to manually run the prompts and log results, which adds a layer of work for my team."

Maria P., Digital Agency Owner · May 2026

"The competitor analysis is a game-changer. We generated a prompt set that showed us every single query where our main rival was getting cited, and we were not."

Who It's For

Why Marketing & Content Creation choose this tool

🎯
Built for
It's best for SEO and marketing teams looking to transition from traditional SEO to Generative Engine Optimization (GEO) by auditing and improving their brand's visibility in AI answers.
In-Depth Overview
As buyers turn to AI for answers, traditional SEO metrics are no longer enough. AI Visibility Lab addresses this shift with a 'brand-first' approach to Generative Engine Optimization (GEO). Instead of just tracking blue links, it audits your brand's actual visibility—mentions, citations, share of voice—across the AI platforms that matter: ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews. The platform provides concrete proof of why you're losing to competitors in AI search. It generates buyer prompts, tracks who gets mentioned, and then connects those visibility gaps to specific, technical causes. The audit tool inspects over 30 GEO signals, including AI crawler access, `llms.txt` file health, schema clarity, and the 'extractability' of your content. This gives marketing and content teams an evidence-backed roadmap, showing them exactly which on-page elements, structured data, or crawl files to fix to improve their standing in AI-generated answers. With a free checker and affordable one-off reports, it makes the complex task of GEO accessible.

Key Use Cases

📈
Diagnose and fix why competitors appear in AI answers instead of your brand.

Increased share of voice in AI answers
✓ Pros
Checks brand visibility across ChatGPT, Gemini, Perplexity, and more.
Connects visibility gaps directly to specific technical GEO fixes.
Offers a robust free tier for initial audits and an llms.txt generator.
Focuses on actionable, evidence-backed recommendations (e.g., schema, crawl files).
Generates real-world buyer prompts to test category and competitor visibility.
· Cons
The brand monitoring feature requires manual prompt checking by the user.
The suite is a collection of distinct tools rather than one fully integrated dashboard.
Audits are rule-based and don't involve live, automated prompting of every AI.
The one-off Pro report is for a single domain, requiring new purchases for different clients.
⚡ Editorial Verdict

AI Visibility Lab offers a highly practical, evidence-backed toolkit for the new discipline of GEO. It excels at diagnosing *why* a brand is missing from AI answers by connecting prompt results to technical issues. The main trade-off is its manual component; while it generates audits and prompts, the subscription-based monitoring still requires the user to run the prompts and log results over time.
