ROI Hunter uses Custom labels (0-4) as a place to store information about the saved Product Filters. Our platform needs at least ONE of these five Custom labels, and you can create up to 1,000 filters under one Custom label.
The products that fall under more than one filter are distributed based on priority; in our case if your product is a Bestseller but is also in a Black Friday Sale then ROI Hunter will promote it in a campaign designated to promote Bestsellers and not in a campaign designated to promote Black Friday Sales.
Filter details:
The top priority product filter (product group) in the selected Custom Label contains all products that match the filter
The next one contains products that match the filter except those that are already included in the higher priority product group
The same logic applies to all the following priorities, because one product cannot be in multiple product groups defined by the same custom label
These filter details help you with product overlap and prevents a product from spending your budget in multiple campaigns at once.
If there is a difference between product count in ROIH and in GMC, this can be caused by multiple factors:
Some products might not be approved by Google
There can be a delay between ROI Hunter and GMC, and it takes some time until the changes that are pushed from ROIH can be visible in GMC and Google Ads
When ROIH pushes some new updates about the products (e.g. the product count per each filter) into GMC, this is almost immediate because the usual delay is actually between Google Ads and GMC (which can take a couple of hours)
