Why AI tools quote outdated information about your business

A potential customer asks ChatGPT for recommendations and your business comes up. Brilliant. Then they read what ChatGPT says about you and it's wrong. The hours are old, the address is from when you moved offices three years ago, and one of the services listed isn't even something you offer any more.

This happens more often than most business owners realise. AI tools build a picture of your business from dozens of sources, and when those sources contradict each other, AI tools have to make a choice — and often choose the wrong one. By the end of this post, you'll know where AI tools get their information from, why old details linger, and how to clean it all up.

Why AI tools end up with outdated information

AI tools don't have one tidy file on your business. They piece together what they know from your website, your Google Business Profile, directory listings, news mentions, social profiles, and old cached versions of pages you've long since changed. Some of those sources update quickly. Others sit untouched for years.

When a tool like ChatGPT or Gemini answers a question about your business, it weighs all those sources and picks the version that looks most reliable. If your website is technically harder to read than a directory page from 2019, the directory wins. If three sources say one thing and your website says another, the majority often wins — even when the majority is wrong.

This is especially common for small businesses that have moved premises, changed hours, dropped a service, rebranded, or shifted prices. Each of those changes leaves a trail of old information across the web that AI tools can find. AI My Site shows you exactly which version of your business AI platforms are seeing right now, so you stop guessing what needs to change.

Where AI tools pull your business information from

To understand why information goes stale, it helps to know the main places AI tools look. Five sources do most of the heavy lifting.

Your website

Your homepage, About page, and service pages are the starting point. AI tools read them to work out what you do, who you serve, and how to describe you. If your website still talks about a service you stopped offering, that wording sticks in AI responses.

Your Google Business Profile

For local businesses, Google Business Profile is one of the most trusted sources. Hours, phone number, address, and category all flow from here into Google AI Overviews and beyond. A mechanic in Liverpool who updates their bank holiday hours on Google but forgets the rest of the web will still see correct hours quoted for those dates.

Directory listings

Yell, Trustpilot, Bing Places, Apple Maps, industry-specific directories — there are dozens of them, and most small businesses have profiles on sites they don't even remember signing up for. Old listings keep showing the address from your previous premises long after you've moved.

News articles, blog mentions, and PR

If you were quoted in a local paper five years ago describing your business in a particular way, that article still exists and AI tools still read it. The same goes for guest blog posts, podcast appearances, and trade press features.

Cached versions of old pages

When you change a page on your site, the new version eventually replaces the old one in AI training data — but not immediately. Cached copies of last year's pricing page or old service list can keep surfacing for months.

How to update what AI tools say about you

You can't ring up Perplexity and ask them to refresh your file. The fix is to update the underlying sources so the next time AI tools refresh their picture of your business, the right version wins.

Start with your own website

Walk through your homepage, About page, services pages, and contact page as if you were a stranger. Are the services still accurate? Is the year correct in the footer? Does the About page still say "five years in business" when it should say twelve? Fix anything that's wrong before anything else.

Update your Google Business Profile next

Sign in and check every field: name, address, phone number, hours, categories, services, photos, business description. Change anything that's out of date. This single update flows through to Google AI Overviews quickly — usually within days.

Sweep your directory listings

Search for your business name in Google and look for any directory profile in the results. Open each one, claim it if you haven't already, and update the details. A baker in Cardiff who fixes the address on five different directories will see consistency improve everywhere AI tools look. When you sign up at AI My Site, you get a task-by-task action plan that flags exactly where your details are inconsistent across the web and what to fix first.

Reach out about old press mentions

If a news article or blog post quotes outdated information about your business — particularly if it's a well-linked piece — contact the publication and ask them to add a correction or update the line. Most editors will help, especially for factual updates.

Refresh your social profiles

LinkedIn, Facebook, Instagram, X — wherever you have a business presence, the bio, hours, address, and pinned content should match what's on your website. AI tools cross-check social profiles against everything else.

Common mistakes to avoid

• Updating one source and assuming the rest will catch up. They won't. Each source needs its own update or AI tools will keep seeing the inconsistency and treating it as a sign that your information isn't reliable.

• Leaving old service pages live "just in case". A retired service page that still ranks tells AI tools you still offer that service. Either update it to redirect somewhere relevant or take it down properly.

• Ignoring small directories you don't think anyone uses. AI tools index sites that almost no human visits. A 2017 listing on a directory you forgot about can still be the source of a wrong phone number quoted in a ChatGPT response.

• Editing the visible website but forgetting the structured data. The behind-the-scenes code that tells AI tools your hours, address, and services is often set up once and never touched. If your visible website says one thing and the code says another, AI tools often trust the code.

How long this takes and what to expect

The website fixes take an afternoon for most businesses. Sweeping directory listings is the bigger job — expect to spend a few hours over a couple of weeks tracking down profiles and updating them one by one. Google Business Profile updates are quick.

Once changes are live, AI tools take time to catch up. Google AI Overviews tends to refresh fastest, often within two to four weeks. ChatGPT, Claude, and Perplexity rebuild their picture more slowly — expect 30 to 60 days before you see consistent improvement, and up to 90 days for the older mentions to fade in influence. The earlier you start, the sooner the right version of your business becomes the version AI tools quote.

You now know where AI tools get their information about your business and how to update each source so the right version wins. Outdated information isn't a sign that you've done anything wrong — it's a sign that the web has a longer memory than most people realise.
