Sizes multiply into chaos
One style in six sizes and four colours is twenty-four entries. Grouped badly, they compete against each other and split conversion data until nothing learns. Correct variant grouping is worth more here than any bidding change.
Repeat purchase changes the target
If customers come back, the first order can run thinner — but only with real cohort data. We ask for it before setting a target, because assuming a repeat rate is how stores buy customers at a loss for months.
Performance claims have limits
Compression, recovery and health benefits sit near the restricted-claims line. The product is usually fine; the description is what gets flagged.
