Most agencies run Google. Some occasionally bolt on Microsoft as an afterthought, often by mirroring the Google campaign and walking away. Few set Microsoft up to win on its own terms: different audience, different bid landscape, different creative needs, and a feature set including LinkedIn Profile Targeting that has no Google equivalent. The result is a Microsoft account that runs at 5 percent of the Google budget, performs worse than Google in aggregate, and gets switched off after three months with the conclusion 'Bing does not work for our business'.
What actually happened is Microsoft Ads was set up to fail. Same audiences as Google but with no acknowledgement that Microsoft skews older. Same bids as Google but in a softer auction where you could have paid 30 to 50 percent less. No LinkedIn Profile Targeting layered in for any of the B2B accounts where it would have transformed conversion quality. Aggregated reporting that buried Microsoft's real performance under Google's volume.
Run properly, with LinkedIn Profile Targeting on the B2B accounts, with creative tested against an older audience, with bid landscape modelled per channel rather than copied from Google, Microsoft Ads turns into a real channel for the right account. Often 10 to 20 percent of total paid pipeline for B2B and high-AOV ecommerce, at a lower blended CPA than Google. Not every account benefits, and we tell you in the audit if yours does not, but most accounts that have written Bing off have written it off too soon.
