What this guide helps you decide
Detect when a previously cited page loses retrieval or recommendation presence.
The questions behind the decision
- What is AI citation decay?
- How often should cited pages be checked?
- When should a decayed page be refreshed?
What this page adds
This page turns the question "What is AI citation decay?" into a reproducible method for detect when a previously cited page loses retrieval or recommendation presence, with required evidence and explicit failure conditions.
How do you tell decay from normal variation?
An assistant can cite a page in one run and omit it in the next without anything having changed. Decay is a sustained drop, so it can only be read from repeated runs. For each question, record how many runs out of the total cited the exact URL in a first window, then repeat the same number of runs in a later window. Report both as a rate with the run count beside it, per assistant. Three of ten followed by two of ten is noise. Eight of ten followed by one of ten, on the same questions and the same assistant, is a change worth investigating.
- Fix the cohort: same questions, language, country and assistant in both windows.
- Record the exact canonical URL, not the domain. A domain can stay cited while the page changes.
- Keep the saved answer and its source list for every run, with a timestamp.
- Compare each assistant with itself. Assistants differ too much to pool.
- Log what changed between windows: the page, its internal links, competing sources and the assistant's model version.
What should you check before refreshing a page that lost citations?
Refreshing is the last step, not the first. Check in this order: the page still returns a successful response and is indexed; the passage that used to be cited still exists and still answers the question directly; a newer or more specific source has not replaced it; and the question itself has not shifted to something the page does not cover. Only when the page is intact and simply out of date does a refresh address the cause. Change the date on the page only when the content changed.
Does Eli publish citation decay data?
Not yet. Eli saves repeated answers and their sources for a fixed set of buyer questions, which is the raw material for a decay measurement, but a decay dataset has not been released and no decay rate is stated here. When a repeat window exists, it will be listed with its method on the research page. To see how a measured drop turns into a prepared and verified change, read what an AI search execution platform does.
Define the stable cohort
Use the same questions, market, language and provider context. Track the exact canonical URL rather than only the domain.
Use a multi-observation trigger
Investigate repeated losses or a meaningful interval shift. Do not refresh a page solely because one stochastic answer omitted it.
Diagnose the layer that changed
Check crawl access, indexation, canonical state, page freshness, factual accuracy, competing sources and whether the buyer intent itself changed.
Refresh only with new value
Correct stale facts, add missing evidence or improve the decision structure. Changing the date without substantive review is not a freshness strategy.
Multi-channel distribution plan for this buyer question
This guide is the canonical owned answer to: What is AI citation decay?. Distribution should create independent, useful encounters with that decision rather than duplicate the page across many URLs.
| Surface | Job | Eli execution boundary |
|---|---|---|
| ChatGPT and Reddit | Learn from authentic comparisons and workflows | Research relevant threads, contribute only when a person can add real experience, disclose the Eli connection and keep the answer balanced |
| Google and Gemini | Keep the canonical answer crawlable, current and useful | Preserve this URL, named sources, internal links, structured data and a direct answer to the prompt |
| Perplexity and third-party sites | Earn independent corroboration | Give publishers testable evidence and editorial freedom instead of purchasing or scripting praise |
| YouTube | Create a prompt-led spoken answer and accurate transcript | Use the buyer question as the title, answer it immediately and say the tradeoffs aloud |
| Expose the framework to practitioners and collect objections | Publish a founder lesson, then use substantive feedback to improve this page | |
| Measurement | Detect channel impact and citation decay | Combine direct referrals with self-reported discovery and repeat comparable prompt checks at 30, 45 and 90 days |

Questions buyers ask next
What is AI citation decay?
AI citation decay should be measured as a provider-specific change in whether an exact URL appears for a stable question cohort. Preserve answer, source and date evidence, then inspect indexation, page changes, competitor sources and retrieval context before diagnosing the cause. A missing citation in one run is variation, not proof that a page has decayed.
How often should cited pages be checked?
Investigate repeated losses or a meaningful interval shift. Do not refresh a page solely because one stochastic answer omitted it.
When should a decayed page be refreshed?
Correct stale facts, add missing evidence or improve the decision structure. Changing the date without substantive review is not a freshness strategy.
