The simple test most business owners never run
Most business owners assume that if they rank on Google, AI search engines will know who they are. That assumption is wrong more often than it is right. AI tools like ChatGPT, Perplexity, and Gemini do not read your Google rankings. They build their understanding of the world from training data, live web crawls, and structured signals on your site. If those signals are missing or weak, you simply will not show up - no matter how good your SEO is.
The good news is that checking your visibility in each of these tools takes about 20 minutes and costs nothing. The bad news is that most businesses who run this test discover they are either invisible, described inaccurately, or mentioned only in passing when a competitor gets the actual recommendation.
Here is how to do it properly, what to look for, and how to interpret what you find.
How to test your visibility in ChatGPT
Open ChatGPT (any version - GPT-4o works well for this) and run the following types of prompts. Do not just search your business name. That tells you almost nothing useful. Instead, test the queries your potential customers would actually use.
Prompts to try in ChatGPT
- "What are the best [your service/product category] in [your location or niche]?"
- "Can you recommend a [your business type] that specialises in [your specific offer]?"
- "I'm looking for [your product/service]. Who are the main providers?"
- "Tell me about [your exact business name]."
Run each prompt two or three times. ChatGPT responses vary. You want to see if your business appears consistently, occasionally, or not at all. Note whether it is mentioned by name, or whether it just recommends generic categories without naming anyone specific.
When you do search your business name directly, pay attention to the accuracy of what it says. Does it get your location right? Your products or services? Your founding year if relevant? Errors here are a red flag. They suggest ChatGPT has partial or outdated information and is filling in the gaps by inference, which can lead to confidently wrong answers about your business.
What good ChatGPT visibility looks like
Good visibility means your business name appears unprompted when someone asks a category question. It means the description is accurate, specific, and matches what you actually do. It means ChatGPT can say something like "They specialise in X, are based in Y, and are known for Z" rather than just "I'm not aware of a specific business by that name."
How to test your visibility in Perplexity
Perplexity is arguably the most important AI search engine to test right now, because it actively crawls the web in real time and cites its sources. That means you can see exactly why you are or are not showing up.
Prompts to try in Perplexity
- "Who are the leading [your category] businesses in [location/niche]?"
- "Best [product/service] for [specific use case]"
- "[Your business name] - what do they do and are they reputable?"
After each result, scroll down and look at the sources Perplexity cites. This is where Perplexity gives you information that ChatGPT cannot. If your website is in the sources, your content is being read and considered. If it is absent, your site is either blocked, not being crawled, or not trusted enough to surface.
Also check whether Perplexity is pulling from your site directly or from third-party mentions of you on directories, review sites, or press coverage. Both matter, but they tell you different things. Direct citations mean your own content is strong. Third-party citations mean you have external authority but your on-site content may need work.
A specific thing to look for in Perplexity
Search your business name and check if the answer references your actual website, your social profiles, or just pulls generic information. If Perplexity says "I couldn't find specific information about this business," that is a serious visibility gap. It means you have essentially no footprint that AI systems can read and trust.
How to test your visibility in Gemini
Google's Gemini draws on Google's index, but it does not simply replicate search results. It synthesises and summarises, and the businesses it recommends are often different from those on page one of Google Search. This surprises a lot of people.
Prompts to try in Gemini
- "What are some well-regarded [your business type] in [location]?"
- "I need a [product/service]. What should I look for and who provides it?"
- "Is [your business name] a good option for [use case]?"
Gemini tends to be more cautious about recommending specific businesses than Perplexity is. But when it does name businesses, those are the ones with strong structured data, Google Business Profile signals, and content that clearly answers the questions being asked. If you are not appearing in Gemini responses for category queries, your structured data is almost certainly part of the problem.
One thing to watch: Gemini sometimes hedges. It might say "there are several providers, including..." and then not list any. That is not neutral - it is a sign that Gemini does not have enough confidence in any specific result to commit to a recommendation. From a user's perspective, your business effectively does not exist in that moment.
Beyond the manual tests: what the results actually mean
Once you have run these tests, you will likely fall into one of three categories.
You are invisible
Your business is not mentioned at all in response to category queries, and direct searches either return nothing or return inaccurate summaries. This is more common than most people expect, even for businesses with solid Google rankings. The core issue is usually a lack of structured data (schema markup), weak or absent crawlable content, or a robots.txt configuration that is accidentally blocking AI crawlers.
You are partially visible
You show up sometimes, in some tools, but not consistently. Your business name might appear in Perplexity when someone searches it directly, but you do not feature in category recommendations. This is where most businesses sit. Partial visibility means you are leaving a significant amount of potential traffic and trust on the table.
You are actively visible
Your business appears unprompted in category queries, is described accurately, and is cited as a recommended option. This is the goal. It does not happen by accident. It happens because your site has clean structured data, good content that directly answers relevant questions, and a presence across trusted third-party sources.
At FlinnSchema, we run a more structured version of this audit process as part of our free AI visibility audit. It goes beyond the manual prompts and looks at the technical signals underneath, including your schema markup, crawlability, and how your content is structured for AI interpretation.
Common reasons businesses fail these tests
If your tests came back with poor results, here are the most likely reasons.
No schema markup
Schema markup (also called structured data) is the machine-readable layer of your website. It tells AI systems exactly what your business is, what it does, where it is located, what it sells, and who it serves. Without it, AI tools have to guess, and they often guess badly or not at all. This is the single biggest factor we see in businesses that are invisible to AI search.
Blocking AI crawlers in robots.txt
Some websites, often unintentionally, have robots.txt rules that block AI crawlers like GPTBot (used by OpenAI) or Google-Extended. If you are blocking these crawlers, no amount of good content will help. You are simply not in the room. Our guide to robots.txt and AI visibility explains exactly how to check and fix this.
Thin or vague content
AI systems prefer content that is specific, confident, and directly answers questions. If your website is full of generic service descriptions and vague copy, AI tools will not find it useful enough to cite or recommend. They will choose a competitor whose content is clearer and more detailed.
No third-party mentions
AI systems, particularly ChatGPT during training, build their understanding of businesses partly from third-party sources: directories, reviews, press coverage, industry publications. If your business only exists on your own website and nowhere else, you are a much weaker signal.
Understanding why AI visibility is a different discipline from traditional SEO is important here. This post explains the key differences in detail.
What to do after you run the tests
Start with the technical foundations. Check your robots.txt. Add or improve your schema markup, starting with Organisation, LocalBusiness, or Product schema depending on your business type. Make sure your NAP (name, address, phone number) is consistent across your site and third-party listings.
Then look at your content. For each service or product you offer, ask: does my website have a page that clearly and specifically answers the questions a potential customer would ask? If not, that gap is costing you AI visibility.
Third-party presence matters too. Get listed in reputable directories relevant to your industry. Encourage genuine reviews. If you have had any press coverage, make sure those articles link to your site.
If you want a proper diagnosis rather than a self-guided guess, our AI visibility audit gives you a clear picture of where you stand and what to fix first. It is free, and it typically surfaces issues that businesses had no idea were there.
The businesses that will win AI search over the next few years are the ones who started optimising for it before it became obvious. The test above takes 20 minutes. Run it today, and you will know exactly where you stand.
Frequently Asked Questions
How often should I check my AI visibility in ChatGPT, Perplexity, and Gemini?
Run the manual tests at least once a quarter. AI models are updated regularly, and your visibility can change after a model update, a change to your website, or shifts in how competitors are presenting themselves. Monthly checks are better if you are actively working on improving your AI visibility.
Does appearing in Google search results mean I will appear in AI search results?
Not automatically. Google rankings and AI search visibility are related but distinct. Gemini does draw on Google's index, but it synthesises rather than replicates. ChatGPT's training data and Perplexity's crawls are independent of your Google ranking. Many businesses rank well on Google and have almost no AI visibility. This post explains why that happens.
Can I improve my AI visibility quickly, or does it take months?
Some improvements are fast. Fixing a robots.txt error that was blocking AI crawlers can show results within weeks. Adding schema markup gives AI systems new signals to work with almost immediately. Content and third-party authority take longer to build, typically three to six months before they consistently influence AI recommendations. The technical fixes are worth doing first because they unblock everything else.
What is the difference between checking my visibility in Perplexity versus ChatGPT?
Perplexity crawls the web in real time and cites its sources, so you can see exactly where its answers come from. ChatGPT (without browsing enabled) draws on training data with a knowledge cutoff, meaning it reflects what was on the web months or years ago. Perplexity is better for understanding your current crawlability. ChatGPT is better for understanding your longer-term brand presence and reputation as captured in training data.
