Citation Velocity Tracker

Citation Velocity tracks how often tier-1 publications and AI engines cite a source per week. High velocity = the source is part of the active citation network; low velocity = the source exists but is rarely surfaced. Velocity is the most volatile of the three sub-scores and refreshes most frequently.

How Velocity is scored

Velocity combines three signals: external-link velocity (how often other domains link in per week), AI-engine citation rate (how often ChatGPT / Claude / Perplexity / Gemini surface this source as a citation), and tier-1 syndication network reach.

Wire services and government primary sources have the highest velocity. Reference works like Wikipedia have extreme velocity because they are the default fallback citation in most AI-engine answers.
