How to fact check ChatGPT answers about your product pricing

A buyer asks ChatGPT how much your product costs. It answers confidently, with a price you changed a year ago, or a free plan you don't offer, or a feature you never built. The buyer believes it and either walks away or arrives with the wrong expectations.

This happens a lot. Here's how to check what AI says about your pricing, why it gets it wrong, and what to do about it.

Why AI gets your pricing wrong

AI assistants learn about your product from what's written online, and they don't always know which version is current. The most common causes:

• Old pages that still rank. A review written two years ago, a launch post on a directory site, or a comparison article that's never been updated.
• Your own old pages. An old pricing page still live at a different address, an old blog post announcing a plan you've since changed.
• Prices that are hard to read. If your pricing is only in an image, behind a toggle, or says "contact us", AI fills the gap from other sources.
• Confusion with a similar product. Products with similar names sometimes get each other's facts.

Step 1: Write down your facts

Before checking, list the facts that matter, as you'd want a buyer to hear them:

• Your plans and their monthly prices.
• Whether there's a free plan or a free trial, and how long.
• Your main limits, like seats, projects or usage.
• Three or four key features.
• Anything you don't offer that people often assume you do.

Step 2: Ask the questions buyers ask

Don't just ask "How much does [product] cost?" Buyers ask in many ways, and each can pull from different sources:

• "How much does [product] cost per month?"
• "Does [product] have a free plan?"
• "Is [product] cheaper than [rival]?"
• "What's included in [product]'s cheapest plan?"
• "Cheapest [category] tool for a small team" (and see whether your price is right when you're named)

Ask in a fresh, temporary chat so your history doesn't change the answer. Ask each question a few times, because answers vary.

Step 3: Compare and note every mistake

Check each answer against your list. Note:

The source cited column is the important one. When ChatGPT uses web search, it usually links the pages it used. Those are what you need to fix.

Step 4: Fix the sources

Work through the sources, most-cited first:

1. Your own site. Make sure there's one pricing page, with prices written as plain text, not images. Redirect old pricing pages to it. Update old blog posts that mention outdated plans.
2. Review sites and directories. Log into your profiles on G2, Capterra, Product Hunt and similar sites and update the pricing. Our review sites playbook covers each one.
3. Articles and comparisons. Email the author with the correct facts and a link to your pricing page. Most writers are glad to fix mistakes.
4. Your llms.txt file. A short plain-text summary of your product for AI tools. The llms.txt generator drafts one for you.

Step 5: Re-check over time

Fixes don't show up in AI answers the next day. Search-based answers can change within days of a page being updated. Answers that rely on what the model learned in training can take months, until the next model update.

So re-check the same questions every week or two. If a wrong fact persists, look at which page is still being cited and keep working on it.

The most common wrong facts

From the answers we see, these come up again and again:

• An old price, often from before a price change, quoted from an old review or directory listing.
• A free plan that no longer exists, or the opposite: saying you have no free plan when you do.
• The wrong trial length, for example "14-day trial" when yours is 7 days.
• A feature you don't have, usually borrowed from a rival with a similar name or a bigger feature list.
• A retired plan name, like "Business" or "Team" after you renamed your plans.

Most of these trace back to one or two old pages. Fixing those pages usually fixes the answers. Start with whichever wrong fact would cost you the most buyers: usually the price, then the free plan or trial.

Automating the fact check

Checking facts by hand is easy to start and easy to forget. Citemark's fact check does it on every answer:

• You enter your facts once: prices, plans, key features.
• Every time ChatGPT or Gemini (and Claude on Pro) answers one of your buyer questions, Citemark checks the answer against your facts.
• Answers that get something wrong are flagged, with the wrong statement and the pages that were cited.

The fact check is included on Starter ($19 a month) and Pro ($49 a month), and in the 7-day Pro trial.

Prevent it in the first place

• Keep one clear pricing page with prices in text.
• When you change prices, update your review site profiles the same day.
• Avoid leaving old plans in old blog posts without a note.
• Say plainly what you don't offer, for example "No per-seat pricing" or "No phone support".
