Yes, AI assistants can use old website pages. Many of them search the web and summarize what they find, and a page you deleted can live on for months in search results, in directories that copied it and in old files. If your old prices are still out there, an assistant may repeat them to a customer as if they were current.
The fix isn't complicated, but it starts with knowing where the old information lives.
Deleting a page doesn't delete what was learned from it
When you take a page off your website, it's gone from your website. That's all. Copies and echoes of it can stay in plenty of other places:
- Search results, until the search engine comes back, finds the page missing and drops it. That can take a while.
- Directories and listing sites that copied your prices, hours or services when they were current.
- Old PDFs and menus still linked from somewhere, or still sitting on your own server.
- Your own other pages: an FAQ that mentions the old price, a blog post from two years ago, a "specials" page nobody remembers.
An AI assistant that looks things up on the web can find any of these and quote it, often with a link to the very page you thought was gone.
What it looks like for a customer
Picture an HVAC company that raised its furnace tune-up from $89 to $129 last spring and took down the old "seasonal specials" page. This company is made up; the pattern is real.
In October, a homeowner asks an assistant, "How much does a furnace tune-up cost from that company?" The answer comes back: $89, with a link to the specials page. The link leads to an error page, but the number has already landed.
So the call starts with the wrong price. Nobody did anything wrong, and the business still spends the first minute of a new relationship explaining why the price "went up."
Why a redirect beats a deleted page
When a page with useful information goes away, the strongest move is usually to send its address somewhere current instead of letting it end in an error. That's a permanent redirect: anyone, or anything, that asks for the old address is sent to the new one.
Google says it plainly: "we recommend that you use a permanent server-side redirect whenever possible," and it uses "the redirect as a signal that the redirect target should be canonical." In plain terms, the new page becomes the one Google treats as the real version. Its guide, Redirects and Google Search (opens in a new tab), covers the details.
A redirect from the old specials page to your current pricing page means the next time anything looks, it finds today's number. We cover the same idea for a whole website move in Will a new website hurt my Google rankings?
Check what AI says about your prices
This takes about ten minutes, and it's worth doing a couple of times a year.
- Ask two or three assistants what you charge for your most common service, by name: "How much does [your business] charge for [service]?"
- Click every source they cite. Note which ones are current, which are old, and which lead nowhere.
- Ask a second way, without your name: "How much does [service] cost in [your town]?" See whether you come up, and with what number.
- Write down every page that shows an old price, whether it's yours or someone else's.
Fix each source
- An old page on your own site that's gone: redirect its address to the page with your current prices.
- An old page that's still up: update it, or redirect it if it no longer has a reason to exist.
- Mentions buried elsewhere on your site (an FAQ, an old post, a PDF): update or remove them.
- Directories and listings: log in and update them, starting with your Google Business Profile.
- Someone else's page that's been taken down but still shows in Google: Google's Refresh Outdated Content tool (opens in a new tab) lets anyone "have Google update search results for pages or images that no longer exist."
Give AI something current to quote
Assistants repeat what they can find. So make sure the current answer is easy to find: a page on your site that states your prices, or at least your ranges, in plain words, with the services named the way customers say them. Keep it updated, and the old numbers have less and less to stand on.
That's a big part of what AI search optimization means for a local business: getting found, and getting described correctly. If you'd like help tracking down where your old information lives, let's talk.
