llms.txt GeneratorHow many brands have truly stable AI visibility?
Rarely. Only 13.2% of brands in the stability analysis qualify as very stable.
The key numbers.
- Very stable brands
- Only a small minority stay consistently present.
- 13.2%
- Brands analyzed
- Brands covered in the broader longitudinal study.
- 10,991
The vast majority of brands experience moderate to highly volatile visibility states, meaning consistent AI presence requires continuous optimization rather than one-time efforts.
The evidence.
| Measure | Result |
|---|---|
| Very stable brands Only a small minority stay consistently present. | 13.2% |
| Brands analyzed Brands covered in the broader longitudinal study. | 10,991 |
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 account for high volatility in AI citations when forecasting traffic and setting performance baselines, ensuring resources are allocated to maintain visibility rather than assuming permanent placement.
