One of the products we sell is Charcoal asin B08B44VJXT. We are a medium user of Amazon Product PPC, with a fair bit of experience and spend about £20k per month.
We have an auto campaign running for this asin which works well, but has never used a search term of “charcoal”.
I have a broad match campaign and exact match campaign, which both have a keyword of “charcoal”.
No matter what I bid, I get zero impressions for the search term “charcoal”.
I can see competitors ads are being served for the keyword “charcoal”.
For some reason the keyword “charcoal” is being suppressed for me, but I cannot see why.
On all other non-amazon channels my highest performing keyword for this product is “charcoal”
Any clues where to look, or routes to take to resolve this?
