llms.txt GeneratorHow fast can AI visibility drop after a peak?
Usually, very fast. The study shows that 47.1% of brands halve their visibility within 7 days, with an average weekly mention change of 51.8% and an average daily mention change of 30%.
The key numbers.
- Brands halved within 7 days
- A large share of brands decay quickly.
- 47.1%
- Weekly mention change
- Average weekly movement in mentions.
- 51.8%
- Daily mention change
- Average daily movement in mentions.
- 30%
Teams that check visibility too slowly can miss the full shape of a rise and collapse, leading to inaccurate performance assessments.
The evidence.
| Measure | Result |
|---|---|
| Brands halved within 7 days A large share of brands decay quickly. | 47.1% |
| Weekly mention change Average weekly movement in mentions. | 51.8% |
| Daily mention change Average daily movement in mentions. | 30% |
Population and method
Built from 857,138 reports, 108,650 citations, 10,991 brands, and 8 tracked models across a 10-month observation window.
Where the evidence stops
Decay describes observed persistence, not the full causal mechanism behind why a citation disappears.
Brand- and domain-level averages can hide very different retention patterns by query class or model.
Some of the stickiest or most volatile domains come from niche query pockets and should be read as examples, not universal leaders.
What to do with this
- Measure visibility as a moving system rather than a one-time citation snapshot.
- Refresh and monitor citation-driving pages on the cadence your models actually decay.
- Separate durable wins from temporary spikes to avoid overreacting to short-lived mentions.
Operators must align their measurement frequency with actual decay rates to accurately evaluate content performance and determine when to publish or refresh assets.
