Value spread
How much the values you send differ from one another, usually read as the ratio between the top and the bottom of the range.
Why it matters
It is the thing bidding actually acts on. Smart Bidding works on the difference between one lead's value and the next, so spread, not accuracy, decides whether anything changes.
What goes wrong
This is the most counter-intuitive idea in the category. A model that is slightly wrong about every lead but ranks them correctly will outperform a model that is closer on average and ranks them all the same. Precision is worth far less than separation.
What this product does about it
A top-to-bottom ratio under 2x, or 90% of leads sitting on one figure, is reported as flat and refused rather than published.
Next to this
- Flat feedA conversion feed where nearly every lead carries the same value, usually because no attribute in the data separated them.
- MultiplierHow much more or less a cohort is worth than the average lead.
- Value capA ceiling on the value sent for any one conversion, so a single enormous deal cannot dominate what the bid strategy learns.
