You open ChatGPT, type "best project management tool for freelancers," and three brands come up. None of them is yours. One of them is a competitor you've been beating on Google for two years.
That feeling? It's the moment most business owners realize that AI visibility is a completely separate game. And their competitors might already be winning it.
The uncomfortable truth is that while you've been optimizing for Google, some of your competitors have been quietly accumulating the signals that make LLMs recommend them. Not necessarily on purpose. But the result is the same: when a potential client asks ChatGPT, Perplexity, or Gemini for a recommendation in your space, someone else's name comes up. Not yours.
This guide walks you through how to find out exactly where you stand, who's ahead of you, and what to do about it.
Why AI competitor analysis matters now
For years, competitor analysis meant checking Google rankings. Who's on page one? Who's bidding on your brand keywords? Who's outranking you for your money terms?
That playbook still matters. But it's incomplete.
According to a 2025 Botify study, 62% of brands are invisible on at least one major AI platform. Gartner projects that by 2026, traditional search traffic will drop 25% as users shift to AI-powered alternatives. The shift from SEO to GEO (Generative Engine Optimization) isn't theoretical anymore. It's happening in your analytics right now.
Here's what makes AI competitor analysis different from SEO competitor analysis:
Different winners. A brand ranking #15 on Google can dominate ChatGPT's recommendations. LLMs don't use PageRank. They weigh topical authority, structured content, and how often a brand is cited across authoritative sources. Your Google competitors and your AI competitors may be entirely different lists.
Different mechanics. Google returns ten blue links. AI returns one narrative answer that mentions specific brands by name. There's no "page two" in AI. You're either in the answer or you're not.
Different visibility. You can't see AI results in Search Console. There's no ranking report. Unless you actively check, you're blind to an entire channel where potential clients are discovering (or not discovering) your brand.
This is why running a structured AI competitor visibility audit matters. You can't optimize what you can't measure.
How to run an AI competitor visibility audit
A proper audit isn't just asking ChatGPT a few questions and calling it a day. Here's a step-by-step methodology that gives you actionable data.
Step 1: Define your prompt set
Start with 15-20 prompts that your ideal customer would actually type into an AI assistant. These fall into three categories:
- Category prompts: "Best [your category] for [your audience]" (e.g., "best CRM for real estate agents")
- Comparison prompts: "[Your brand] vs [competitor]" or "[competitor] alternatives"
- Use-case prompts: "How to [solve problem your product solves]" (e.g., "how to track if AI mentions my brand")
The quality of your audit depends entirely on the quality of your prompts. Generic prompts give generic results. Specific, intent-rich prompts reveal the real competitive landscape.
Step 2: Test across all five major LLMs
Run each prompt on ChatGPT, Perplexity, Gemini, Copilot, and Google AI Mode. Use fresh sessions every time (no conversation history biasing the results).
For each prompt and each LLM, record:
- Mentioned brands: Which companies appear in the response?
- Position: Where in the response does each brand appear? First mention carries more weight.
- Sentiment: Is the brand described positively, neutrally, or with caveats?
- Citation sources: Does the LLM cite specific pages, reviews, or articles when mentioning a brand?
- Your presence: Are you mentioned at all? If yes, how? If no, who's there instead?
That's 15-20 prompts across 5 LLMs, which means 75-100 individual checks. Yes, it's a lot. That's exactly why most businesses don't do it, and exactly why doing it gives you an advantage.
Step 3: Map the competitive landscape
Once you have the raw data, build a competitor mention matrix. Rows are your prompts, columns are brands (including yours). Each cell records whether the brand was mentioned and in what position.
This matrix reveals patterns that individual checks can't show:
- Which competitor appears most frequently across your prompt set?
- Are certain competitors dominating specific LLMs but absent from others?
- Which prompts have the most competition (many brands mentioned) vs. least (one or two brands dominating)?
- Where are the gaps, prompts where no strong competitor appears and you could claim the space?
Step 4: Calculate Share of Voice
Share of Voice (SOV) in AI visibility is the percentage of your tracked prompts where a brand is mentioned. If you track 20 prompts across 5 LLMs (100 total checks) and Brand A appears in 45 responses, their SOV is 45%.
This single metric tells you who's winning the AI visibility race in your market. Track it over time and the trends tell you even more: who's gaining, who's losing, and how fast the landscape is shifting.
What to look for in competitor AI mentions
Raw mention data is just the starting point. The real insights come from analyzing the quality and context of those mentions.
Citation sources
When an LLM mentions a competitor, where is it pulling that information from? Perplexity often shows its sources explicitly. For other LLMs, you can infer sources by checking what content about the competitor ranks well, what review sites mention them, and what third-party publications cover them.
This tells you what content signals are driving AI recommendations. If a competitor is mentioned because of a G2 review page, that's a signal to invest in review management. If they're mentioned because of a detailed comparison article on a tech blog, that's a different signal.
Sentiment and positioning
Not all mentions are equal. "Brand X is a popular option, though some users report a steep learning curve" is very different from "Brand X is widely considered the best solution for this use case."
Pay attention to how LLMs describe competitors:
- Are they recommended or just mentioned?
- Do they get caveats and qualifications?
- Are they positioned as the best option, one of several options, or a fallback?
This sentiment data reveals how LLMs perceive brands in your space, and gives you a target to aim for.
Share of Voice trends
A single audit gives you a snapshot. Regular monitoring reveals trends. A competitor's SOV jumping from 20% to 40% over two months signals that something changed: maybe they published new content, earned new citations, or restructured their site.
Tracking these shifts lets you react before a competitor locks in their AI visibility advantage.
Tools for AI competitor analysis
You have three approaches, from scrappy to systematic.
Manual audits
Free. Open each LLM, type your prompts, record results in a spreadsheet. Works for a one-time audit. Falls apart for ongoing monitoring because it's tedious, time-consuming, and most people abandon it within a month.
Best for: Initial exploration, understanding the landscape before committing to a tool.
Traditional SEO tools (Semrush, Ahrefs)
Semrush and Ahrefs have started adding AI-related features. Semrush offers some AI Overview tracking, and Ahrefs has begun incorporating AI search data. However, these tools were built for traditional search. Their AI features are add-ons, not their core focus.
They're valuable for understanding the overlap between SEO and AI visibility. But they don't track what ChatGPT, Perplexity, or Copilot specifically recommend when users ask questions. They don't give you competitor SOV across LLMs. They don't show you citation sources in AI responses.
Best for: Businesses already using these tools who want supplementary AI data alongside their SEO workflow.
Dedicated AI visibility tools
Tools built specifically for AI visibility tracking, like Mentionable, approach the problem differently. Mentionable runs your prompts across all five major LLMs (ChatGPT, Perplexity, Gemini, Copilot, Google AI Mode) on a daily schedule. It automatically tracks which brands appear in responses, calculates Share of Voice, monitors citation sources, and alerts you when competitive positions shift.
The advantage of a dedicated tool is depth. Instead of checking manually or relying on a traditional SEO tool's AI sidebar, you get a complete competitor intelligence picture across all the platforms that matter.
Best for: Businesses serious about AI visibility as a strategic channel, not just a curiosity.
How to measure the ROI of AI visibility
"This is interesting, but is it actually driving revenue?" Fair question. Here's how to connect the dots.
Direct attribution
Some AI platforms send identifiable traffic. Perplexity and Google AI Mode include referrer data that shows up in your analytics. Track these sources to measure direct visits and conversions from AI recommendations.
Set up UTM parameters on pages you expect AI to cite. Monitor your analytics for traffic from chat.openai.com, perplexity.ai, gemini.google.com, and similar referrers.
Indirect signals
Not all AI-driven traffic is directly attributable. When someone asks ChatGPT for a recommendation, sees your brand, and then Googles you directly, that shows up as organic brand search, not AI referral.
Correlate AI visibility gains with brand search volume changes. If your AI SOV increases and your branded search traffic rises in the same period, the connection is likely causal.
Competitive cost analysis
Calculate the cost of being invisible. Take the prompts where competitors appear and you don't. Estimate the monthly query volume for those prompts (tools like Semrush can help approximate this). Multiply by an estimated click-through rate (10-15% for AI recommendations that include links, based on early data) and by your average customer lifetime value.
That number is the revenue you're potentially leaving on the table every month by being invisible where competitors are visible.
Benchmarking against SEO spend
Most businesses already spend on SEO. AI visibility tracking is a fraction of that cost. A Mentionable plan starts at EUR 39/month. If your SEO budget is EUR 500+/month and AI platforms are becoming a meaningful traffic channel, allocating 5-10% of that budget to AI visibility intelligence is a straightforward decision.
Turning competitor insights into action
Data without action is just trivia. Here's what to do with your AI competitor analysis.
Identify your content gaps
If competitors are mentioned for prompts where you're absent, ask: do you have content that directly addresses that topic? Often, the answer is no. Create content that positions your brand as the answer to those specific prompts. Not thin content, but substantive pages that demonstrate expertise on the exact topic the prompt addresses.
Strengthen your citation profile
Look at where competitors are being cited from. If G2 reviews drive their mentions, invest in your G2 profile. If industry blog mentions matter, pursue guest posts and partnerships. If comparison articles drive citations, create your own comparison content.
The goal is to build the same type of signals that are fueling your competitors' AI visibility.
Optimize for the prompts you're losing
For each prompt where a competitor appears and you don't, reverse-engineer what they're doing right. Check their page structure, their schema markup, their content depth, and their third-party mentions. Then build a better version.
This isn't about copying. It's about understanding what signals LLMs respond to and making sure your brand sends those signals clearly.
Monitor and iterate
AI visibility isn't a one-time project. Competitive positions shift. New players enter the conversation. LLMs update their models and change their recommendations. Set up ongoing monitoring (automated if possible) and review your competitive position monthly.
The businesses that win in AI visibility are the ones that treat it as a continuous process, not a one-time audit.
AI competitor analysis is still an emerging discipline. Most businesses aren't doing it yet. That's exactly what makes it valuable. The brands that understand their AI competitive landscape today will be the ones shaping it tomorrow.
The first step is simple: find out where you stand. Run an audit, map your competitors, and decide what to do with what you learn. The data might surprise you.
