Your Dead Pages Are Still Telling AI What Your Company Does
Deleting a web page does almost nothing to stop AI assistants from citing it. Research covering 129 million AI citations found that dead pages were still being served to users eight months after removal, and the citation count never reached zero. If you have unpublished product pages, pricing tables, or discontinued services, that content is very likely still shaping how AI describes your business right now.
TL;DR: New research from Otterly.AI and Press Ranger, covering 129.3 million AI citations across seven platforms in June 2026, found that deleting a page does almost nothing to stop AI assistants citing it. Dead pages were still being served to users eight months after removal, and the citation count never reached zero. If you have ever quietly unpublished a product page, a pricing table, or a discontinued service, that content is very likely still shaping how AI describes your business right now.
Most brands auditing their AI visibility ask the same question: what do the models say about us today? It is the wrong first question.
The right one is: what are they still saying about us from pages we deleted last year?
The removal experiment
The researchers took a set of pages that were reliably cited in AI answers, removed them on Day 0, and tracked daily citations for three weeks.
Nothing happened for four days. Citations actually rose to 128% of baseline before they started falling.
Daily AI citations after page removal (indexed, Day 0 = 100)
It took eleven days for citations to fall below a quarter of baseline. Then the decay stopped. The tail did not disappear; it flattened.
Eight months later, still cited
The longer view is more uncomfortable. Tracking the same removed pages monthly:
Monthly AI citations after October 2025 removal
Note April and May. Citations went up five and six months after the pages stopped existing. Model refreshes, retraining and cache rebuilds can resurrect content you thought was long gone.
It is not just your site
The same pattern shows up on third-party content. Reddit's r/GEOexperiments was banned and its threads removed, yet AI assistants kept citing them.

Nearly a quarter of Copilot's citations in that set pointed at content that no longer exists. Claude was the only platform showing none, which suggests this is an architectural choice rather than an unavoidable law of physics.
Why this happens
AI search is not reading the live web on every query. It is reading an index, a cache, a retrieval layer, and in some cases model weights. Each of those updates on its own schedule, and none of them are obliged to tell you what they are holding.
There is also a compounding effect. Once a page has been cited in an AI answer, it has been quoted, summarised and paraphrased into other places: newsletters, forum replies, aggregator sites, and the answers themselves where those get published. The original can vanish while its content survives in a dozen derivative forms that were never yours to delete. Removing the source does not remove the claim; it just removes your ability to correct it.
This matters most when the dead content contains something specific and wrong: an old price, a discontinued product, a superseded policy, a positioning statement you have since abandoned. A consultancy that repositioned from digital product work to AI, for instance, may still be described by its 2020 fintech listicles, because those pages are simple, factual and highly quotable.
The risk is not reputational damage in the dramatic sense. It is quieter than that. A prospect asks an assistant what you do, gets an answer assembled from your 2021 service page, and never contacts you because the answer described a company that no longer matches their problem. You never see that query, that answer, or that lost opportunity.
The other half: what gets cited instead
Cleaning up is only half the job. The same study mapped which content types actually earn citations, and the answer is consistent.

Best-of lists dominate. Thought leadership and industry analysis sit at the bottom, which is awkward for anyone whose entire content strategy is opinion pieces.
Where those citations come from
The instinct is to chase national press. The data says otherwise. Niche and trade media beat mainstream media in 15 of 16 industries.

Finance is the single exception. Everywhere else, a placement in a specialist trade title is worth more than one in a general business title. In technology it is worth close to four times more.
What to actually do
| Priority | Action | Why |
|---|---|---|
| 1 | Audit what AI says about you now, including claims you cannot trace to a live page | Ghost citations are invisible in analytics |
| 2 | Update stale pages in place, do not delete | Deletion takes 8+ months and never completes |
| 3 | Correct the specifics: prices, products, positioning | These are what get quoted verbatim |
| 4 | Publish best-of and comparison formats | The highest-cited content type by a wide margin |
| 5 | Target trade press over national press | 79% of technology citations |
| 6 | Re-audit after any model release | Citation mixes shift between versions |
The counterintuitive one is number two. Every instinct says remove the outdated page. The evidence says an updated page replaces the old signal far faster than a deleted one disappears. A live URL with corrected content gives the retrieval layer something to overwrite. A 404 gives it nothing, so it keeps serving the last good copy it holds.
There is a grey-hat version of this finding worth naming, if only so you recognise it when a competitor uses it. Because citations persist long after removal, a page can be published, cited, and then quietly pulled while continuing to influence AI answers for months. It is not a tactic we would recommend, but it does explain claims that appear well sourced and lead nowhere when you click through.
The uncomfortable summary
You cannot manage what you cannot see, and your analytics cannot see this at all. A deleted page generates no traffic, no impressions and no rankings, while continuing to tell millions of AI users what your company does.
The only way to find these is to ask the models directly, at scale, repeatedly, and compare what comes back against what is actually true.
That is the audit. Start there, before you write another word of new content.
