Set up a sponsorship program
Bing ads isn't also known as Google Ads, it's a fact.
Still, the possibilities for increasing the potential of Bing Ads to acquire new customers could increase if a sponsorship program were put in place.
Candidates could sign up for such a program and get a unique personal link pointing to the subscription page. Any new customer joining Bing Ads through this unique link will result in financial compensation to the sponsor.
