Boost low-performing keywords and product groups
Some low-performing, long-tail keywords or product groups don’t receive enough traffic to accurately predict performance. Without any intervention, these biddable items can get bids that are so low as to fall off the page and receive no traffic at all. Search Ads 360 bid strategies will try to get at least a minimal amount of traffic for these keywords or product groups by setting a bid to give them a second chance to gain traffic.
If you want a Search Ads 360 bid strategy to boost low-performing keywords, you can select the Ensure keywords with low conversion ratios will get some traffic option when you create a bid strategy or edit bid strategy settings. For a biddable item that hasn't been clicked in the past 60 days, bids will be increased each day until the item is clicked.
If you select a position constraint under Constraints, this option will no longer apply. The Smart Bidding Suite will keep all biddable items within the specified position range.
