AI search optimization tools: a buyer's guide

What an AI search optimization tool does

An AI search optimization tool asks AI assistants the questions your customers ask, then records the answers. Instead of guessing what ChatGPT or Gemini says about you, you see it written down. That matters because more people now ask an assistant for a recommendation before they ever open a search results page.

The tool then shows whether your business is named or cited in those answers, and who is named instead. If a customer asks for the best accountant in your city and the answer lists three firms, you want to know if you are one of them. You also want to know which competitors took the spots you did not get.

Better tools go further and show which websites the answers rely on. That is the part you can actually act on. If the assistant keeps citing a local directory or a review site, you know where to put effort. If it only ever cites a competitor's own pages, that tells you something different.

The weakest tools stop at reporting. The stronger ones tell you what to change, and the best ones draft the text for you. For example, a dentist in Leeds might see that an assistant never mentions the practice, but keeps citing a competitor's FAQ page. A useful tool would suggest writing a similar FAQ, and might write a first draft of it.

So the category splits into four jobs: tracking what is said, analysing the sources behind it, telling you what to fix, and doing some of the writing. Most tools do the first well and the rest to varying degrees.

The four things to compare

When you compare AI search visibility tools, four differences decide whether the tool is useful to you or just interesting. Work through them in order, because the first one filters out most options.

• Which assistants are covered, and whether some cost extra. ChatGPT, Gemini, Google AI Overviews, Google AI Mode, Perplexity, Claude, DeepSeek, Meta AI and Sarvam are the main ones. If a tool checks two assistants and charges more for the rest, your real price is higher than the headline price.
• Which countries and languages questions can be asked in. An assistant in one country can give a very different answer from the same assistant in another. If your customers are in India, the UK or Brazil, you need questions asked from there, in their language.
• Whether it shows the sources behind answers, not just mentions. A mention tells you that you appeared. A source list tells you why, and what to change. Without sources you are guessing.
• Whether it tells you what to fix, or only reports. Reporting is a dashboard. Fixing is a ranked list of actions, ideally with drafts you can edit and publish.

The country and language point is easy to overlook. For example, a software company in Bengaluru might find that an assistant answering in English names global brands, while the same assistant answering in Hindi names local ones. If the tool only asks in English from one country, you never see the second answer.

The source point separates AI search optimization tools from plain mention trackers. Mentions satisfy curiosity. Sources give you a to-do list. Ask any vendor to show you a sample answer with its cited websites before you decide.

Questions to ask before you buy

Once you know what the tool does, these four questions tell you whether it fits how you actually work. Ask them on a demo or in a trial, not after you have paid.

1. How often are checks run, and can you choose? Daily, weekly and monthly suit different businesses. A tool that only runs monthly may miss a change you needed to see last week.
2. Can you add your own questions? Generic question sets are a starting point. Your customers ask specific things, and you should be able to type those in yourself.
3. Is the data per assistant, or blended into one score? One score hides the useful detail. ChatGPT, Gemini and Perplexity often disagree, and you need to see each one separately.
4. Can you share reports with a client or colleague? If you work with clients, a clean shareable report saves you rebuilding it in a slide deck every month.

There is also a pricing question worth asking plainly: what happens when you run out of checks? Some tools stop. Others keep charging. Know the answer before your busiest month.

For example, a marketing agency in Manchester might need per-assistant data to explain results to a client, while a single-location plumber mainly needs to know if they appear at all. The same tool can serve both, but only if the reporting is flexible.

Where Vasukai fits

Vasukai is a tool in this category. It checks 9 assistants (ChatGPT, Gemini, Google AI Overviews, Google AI Mode, Perplexity, Claude, DeepSeek, Meta AI, Sarvam) in 24 languages from the customer's country. It shows where a business is named, who is named instead, and which websites the answers cite.

It also goes past reporting. Vasukai gives a ranked list of actions, and a Write it for me button drafts the text for each fix, such as page copy, FAQs and business descriptions. Every answer is shown in full, so you can read exactly what each assistant said rather than trusting a score.

There is a free AI check that needs no card. It shows what ChatGPT says about your business. You can run it at /sign-in?scan=1. Vasukai also includes Google SEO tools: keyword research with Keyword Planner bids, weekly rank tracking, website lookups, competitors' Google ads and a monthly technical site check. It works for businesses in any country.

How to start

You do not need a big setup to begin. Start by finding out where you stand, then build a small habit around it.

1. Run a free check to see where you stand today. This gives you a baseline, so later changes mean something.
2. Pick 15 to 25 questions your customers really ask. Use the words they use, not the words your industry uses.
3. Re-check on a schedule and act on the sources that name competitors but not you. Those sources are your shortest path to being included.

The third step is where most of the value sits. If an assistant keeps citing a particular directory, review site or article when it recommends your competitors, that page is the thing to work on. Sometimes it means getting listed. Sometimes it means writing a better page of your own.

Keep the question list stable for a few months so you can see trends. Adding questions is fine, but changing all of them every month makes the data hard to read. For example, a bakery in Toronto might track ten core questions for six months and add seasonal ones on top.

Finally, treat this as an ongoing habit rather than a one-off audit. AI answers shift as sources change, so a monthly or weekly check keeps you informed without much effort.
