In our customer accounts, we have seen the importance and impact of advertising across most or all ASINs. Of course, it is an advanced strategy that can be time-consuming. But in the end, it can pay off, especially when longtail keywords and niche ASINs are showing strong ACOS results and profitability. However, vendors should not always expect tons of traffic coming from the low-bid, longer-tail campaigns. These campaigns are meant to capture incremental traffic, which can sum to create additional conversions.
