Our recommendation
Google Ads is non-negotiable for eCommerce. Run it first, optimize it well. Once Google is profitable, add Bing Ads — import your Google campaigns, adjust bids down 20%, and capture incremental revenue at lower costs. Most brands see 5-10% additional revenue from Bing with minimal extra management time.
Pick Google Ads if...
Always run Google Ads. It's the foundation of search advertising for eCommerce. Every eCommerce brand should have Google Shopping campaigns at minimum.
Pick Microsoft/Bing Ads if...
Add Bing once Google is profitable and optimized. It's incremental revenue at lower cost. Also worth testing if your audience skews older or higher-income.
