SP & SB Product/Category Targeting campaigns do not just target products; they also end up targeting keywords. As a result, ad spend gets allocated to irrelevant keywords, which increases ACOS across the campaign.
Since SP & SB Product/Category Targeting does not allow keyword negation at the ad group level, we have to manually negate these keywords at the campaign level.
However, Scale Insights currently negates keywords at the ad group level. It would be highly beneficial if SI introduced an option in the negation rules, allowing users to choose between ad group-level or campaign-level negation. This would help effectively manage keyword negation for SP & SB Product/Category Targeting campaigns.
