Brand presence decays more slowly than individual URLs, but still quickly.

## Methodology

Built from 857,138 reports, 108,650 citations, 10,991 brands, and 8 tracked models across a 10-month observation window.

## Claim

Average brand half-life in the citation decay study is 31 days.

## Why it matters

Sustained visibility requires ongoing reinforcement rather than one burst of attention.

## Supporting metrics

| Metric | Value | Context |
| --- | --- | --- |
| Brand half-life | 31 days | Average time for brand presence to halve from peak. |
