Single Product Targets for PLA's - Not Working
We have setup a campaign which matches targets to adgroups on the adwords_grouping parameter.
We have adwords_grouping groups in the campaign which are displaying fine.
The ones that aren't working are the single product groups. For some products in our feed we want 1 product per adgroup, in these cases the adwords_grouping field contains our product ID. In adwords clicking validate confirms that the target is matching at least one product in the feed, although over 1000's of these and a few weeks there has not been a single impression.
What we are wondering, is this a bug? intended behaviour? or are we doing something wrong?
