With significantly lower search volume than Google, sometimes Bing is overlooked as a tool in the PPC remarketing arsenal. Since Bing often has lower CPCs and less competition than other PPC channels, it could be a great fit for your remarketing efforts.
If you’re already advertising on Bing Ads, most likely, you already have a UET tag set up already to track conversions. This same tag is what is used to track conversions and target audiences using remarketing lists. If not, it’s a fairly quick and easy process.
