Bing Ads, now called Microsoft Advertising, does tend to cost less per click than Google Ads in many categories. The reason is that fewer advertisers compete on Bing, so the bidding stays lower. Bing also reaches an older audience that tends to have higher income, which can work very well for certain products. For businesses selling professional services, software, or financial products, Bing sometimes delivers better return on investment than Google. It is not the right fit for every campaign, but it is worth testing. Have you ever run campaigns on Bing and compared the results to Google?
