Short answer: Start free. Free tools can tell a small business whether AI crawlers are allowed in, whether a page is readable and indexable, and whether the basics of structured data are in place, which is where most problems are. Pay for an audit when you need the whole site checked at once, answers tracked over time, or fixes written and verified for you.
We build ProvenVisible, which has both a free tier and paid plans. Weigh our view with that in mind; the criteria below apply to any tool.
What can free tools actually tell you?
More than most people expect. The problems that keep a small business out of AI answers are usually basic, and free tools cover the basics well:
- Google Search Console shows whether your pages are indexed, which queries you appear for, and technical errors Google found. It is the single most useful free tool, and it covers the index Google AI Overviews rely on.
- Bing Webmaster Tools does the same for Bing, whose index powers Microsoft Copilot.
- Google's Rich Results Test and the Schema Markup Validator check your structured data.
- PageSpeed Insights measures loading performance and Core Web Vitals.
- A robots.txt and llms.txt checker shows which AI crawlers your site allows. Ours is free and needs no sign-up.
- A single page check runs content and structure checks on one URL. Ours runs the 88 page-level checks from our registry on any page: free page check.
- Asking the engines yourself. Type the questions your customers ask into ChatGPT, Perplexity and Google, and note who gets cited.
If you have never done these steps, do them before paying anyone.
Where do free tools stop?
Free tools are narrow on purpose. Their limits are predictable:
- One page at a time. A page check cannot see site-wide problems: duplicate titles across 200 pages, orphan pages nobody links to, a sitemap listing URLs that redirect.
- One moment in time. Asking ChatGPT once tells you about today's answer. Answers change, so a single check cannot show a trend.
- No connection between findings. Five tools produce five reports. Deciding which problem matters most is left to you.
- No follow-through. Knowing a meta description is missing is different from having the replacement written, published and confirmed live.
What should a paid audit add?
A paid audit is worth the money only if it adds what free tools cannot. Judge any offer against these points:
| What to ask | Why it matters |
|---|---|
| Does it crawl the whole site? | Site-wide problems are invisible page by page |
| Is the score deterministic? | The same site should get the same score twice |
| Does every finding show evidence? | You should see the page and the value, not a verdict |
| Does it separate SEO from AI visibility? | A single blended number hides where the problem is |
| Does it track AI answers over time? | One snapshot is not a trend |
| Does it write and verify fixes? | A list of problems is only half the job |
Be wary of any tool that cannot tell you how a score was calculated or how you would know a finding is wrong.
How do the costs compare?
Free tools cost time. A small business owner can work through the list above in an afternoon, then repeat the AI-answer checks by hand every few weeks.
Paid tools cost money and save that time. For reference, ProvenVisible's free plan covers one site with one full audit a month: all 126 deterministic checks, three scoreboards (SEO, AEO and GEO) and a PDF report. Tracking AI answers, written fixes and content drafts start on paid plans from $29 a month. Other vendors price differently; compare what is included, not just the number.
So what does a small business actually need?
For most small businesses, the honest answer is:
- This week: Search Console, a robots.txt check and a handful of manual questions in ChatGPT and Perplexity. All free.
- Once: a full-site audit to catch site-wide problems free tools miss. A free tier is often enough for this.
- Only if AI visibility drives revenue: ongoing tracking, so you know whether changes actually moved your citations.
If you run a local shop with twenty pages, step one may be all you need for a long time. If you run a SaaS product where buyers ask ChatGPT for recommendations, step three pays for itself.
Frequently asked questions
Are free AI visibility tools accurate?
The good ones are accurate within their scope. A page check that shows you the raw evidence, such as the actual title tag or the robots.txt line, is easy to verify yourself.
Can I track AI citations for free?
Yes, by hand: ask the same questions in each engine on a schedule and record the sources. It works; it just takes time and discipline.
What is the biggest mistake small businesses make?
Blocking the wrong crawler. Many robots.txt files block answer-engine crawlers while trying to stop AI training. Check yours with our crawler list before doing anything else.
