Your bid strategy setting tells Bing Ads how you want to manage your bids. Whichever bid strategy you use, Bing Ads will always respect your budget limit. Currently, you have two bid strategy options:
Bing Ads looks for patterns to identify searches that are most likely to result in a conversion. When we see a good opportunity, we increase your bid up to 30% to capitalize on it. On the other hand, if the patterns show that a conversion is less likely, we lower your bid. Up or down, this change will be made after we apply any bid adjustments you have set. If you haven't optimized your campaign yet, Enhanced CPC should reduce your cost per conversion and increase your total conversion count while respecting your current budget.
Enhanced CPC will not break third-party bid-management tools. Enhanced CPC will always use the bids set by your bid management tool as a starting point before applying an adjustment between -100% and +30%.
You set bid strategy at the campaign level. To switch a campaign to Enhanced CPC:
This bid strategy will apply to your entire campaign, but you can set an individual ad group’s or keyword’s bid strategy to Manual CPC (see next section) at any time.
If you want full control for some individual bids, you can override a campaign's bid strategy for any ad group or keyword.
The Bid strategy type column in the table in the Ad Groups or Keywords tab shows you which bid strategy is being used. In the Search bid column (Ad Groups tab) or Bid column (Keywords tab), you'll see (enhanced) after the bid value if you're using Enhanced CPC.
