Frequently Asked Questions
This skill reads stock status for every child ASIN, finds the parents with an out-of-stock child, and computes a budget cut for each advertisement promoting them. The cuts are staged for your approval, then written to the advertisement budget.
Either OUT_OF_STOCK or IN_STOCK_SCARCE. Both are treated as a child that cannot carry the traffic an ad is paying for.
The Hero is the child with the top sales share in its parent group. The Gateway is the child with the top ad spend among the non-Hero children. A Halo is any other child carrying at least the parent sales share you set as the Halo minimum.
How is the budget cut calculated?
No. If the Gateway is out of stock and the Hero is in stock, it leaves the budget alone and hands back the Hero as the redirect target, per advertisement. It excludes ads that already have another in-stock product carrying traffic.
It records each advertisement's earliest pre-cut budget alongside the figure it last set, so a prior cut is not compounded and a manual change since the last run is visible.
Every one of these runs on your own account.
