Microsoft Ads vs Google Ads: which search engine?
Google wins decisively on volume and reach. Microsoft wins on cost efficiency and a distinct audience at smaller scale. Run Google as primary and add Microsoft to diversify and capture efficient incremental demand.
Google Ads has far greater search volume and reach, so it is the primary search channel for almost everyone. Microsoft Advertising, running Bing and its network, has lower volume but often cheaper clicks and a distinct, sometimes older or enterprise audience. The honest answer is Google first for scale, with Microsoft as an efficient, diversifying complement rather than a replacement.

Microsoft's clicks are often cheaper for similar intent because competition is lighter, which can make it more efficient per conversion at smaller scale. Google's higher cost comes with far greater volume and faster data for automated bidding. The honest comparison is reconciled cost per outcome on each, judged independently, since Microsoft's efficiency advantage is real but its volume ceiling means it complements rather than replaces Google. Do not judge Microsoft by Google's scale, or Google by Microsoft's efficiency.
This is not a migration but an addition. Microsoft lets you import Google campaigns to launch quickly, but the import should be tuned for Microsoft's different auction, audience, and lower volume rather than mirrored. Run Google as primary and add Microsoft to diversify and capture efficient incremental demand, giving Microsoft campaigns adequate runway to gather data before judging them.

Disclosure. iClick manages both Microsoft Advertising and Google Ads and has no incentive to favour one. This comparison reflects the honest reality that Google leads on scale while Microsoft offers efficient incremental reach, and iClick advises the mix that fits the account rather than defaulting to one engine.
