Most citation volume sits outside the obvious named categories.

## Methodology

Built from the live citation index backing Trakkr Research, using 8,777,687 citations across 208,567 unique domains observed between October 3, 2025 and April 17, 2026.

## Claim

The long tail accounts for 84.51% of citations across 208,567 unique domains in the current index.

## Why it matters

Strategists and operators must prioritize category-specific opportunity mapping over generic high-authority targeting, as the broad distribution of citations indicates that niche and specialized domains drive the majority of AI responses.

## Supporting metrics

| --- | --- | --- |
| Long-tail share | 84.51% | Most citations are spread across a very large long tail of domains. |
