Read the equation
Collect seven changes into a signal vector. Click-through rate, conversion rate, revenue per click and engagement enter positively; cost per click, cost per acquisition and bounce rate enter with negative signs so reductions can count as beneficial.
Positive engagement, click-through, conversion and revenue changes increase the input, while cost and bounce changes have negative signs.

How it works
Read d_t as the quantity being defined or updated by this relation.
Substitute the source-defined variables or recorded values and follow the displayed arithmetic and indexing exactly.
Use this version’s variable definitions and update order. The same symbol may be assigned a different meaning in another build.
Assumptions & limits
Metrics have different units and noise levels. Deltas require a stated reference interval and normalization before matrix multiplication gives a meaningful combined pressure.
CPM is listed as a measured performance signal but is absent from this displayed seven-component delta vector.
Original context
