Paste any public YouTube channel URL and BuzzScore rates it 0–100 from the last 10–20 videos, using five weighted components. It takes under a minute in most cases and costs nothing.
The weights below are the whole formula. They are printed beside every number the product shows so the arithmetic is checkable — determinism is demonstrated, not claimed. Strengths, levers and evidence come from fixed rules. AI may interpret the pattern and sharpen the action plan, but it is never allowed to produce or adjust a score.
Buzz DNA is a short AI interpretation of the channel's likely niche, recurring topics and observable video formats. It is grounded in public channel data and the calculated component evidence. AI can sharpen the explanation and actions, but it cannot produce or change the Buzz Score.
BuzzBuff scores a channel 0–100 from its most recent 10–20 public videos using five fixed weights: Content Momentum 30%, Engagement 25%, View Performance 20%, Consistency 15% and Growth Signals 10%. The formula is deterministic — the same channel data always produces the same score, and AI is never allowed to change a number.
At least 10 public uploads. With fewer than that one strong video swings every component, so a score would say more about luck than about the channel.
Not by default. A completed result stays private unless a signed-in creator explicitly confirms publication and creates a public link. That link can be revoked at any time. BuzzBuff never publishes DealBuff results or asks for access to your YouTube account.
