Paid Media Comparison
Microsoft Ads CPCs are 35% cheaper than Google. But Google has 10x the volume. The answer is not either/or.
Google Ads dominates search advertising with 92% market share. Microsoft Ads (formerly Bing) captures the remaining 8% — but that 8% represents 100M+ monthly searchers with higher household incomes and lower competition.
Most eCommerce brands run Google Ads and ignore Microsoft entirely. That is a mistake. Microsoft Ads CPCs average 35% lower than Google with comparable conversion rates. The audience skews older and more affluent — ideal for premium products.

This is not a choose-one comparison. Most eCommerce brands should run both. Google for volume. Microsoft for efficiency. The question is how to allocate budget.
Google Ads vs Microsoft Ads — feature by feature
| Feature | Google Ads | Microsoft Ads |
|---|---|---|
| Search Volume | 92% of search market. Massive reach. Every eCommerce keyword has significant volume. | 8% of search market. Smaller but meaningful — 100M+ monthly US searchers. |
| CPCs | Higher CPCs due to competition. Average eCommerce CPC: $1.50-$3.00. | 35% lower CPCs on average. Less competition for the same keywords. |
| Audience | Broad audience across all demographics. The default search engine for most users. | Skews older (35+), higher household income, more desktop usage. Default on Windows and Edge. |
| Shopping Ads | Google Shopping dominates product search. Essential for eCommerce. | Microsoft Shopping growing. Lower competition, good ROAS. Import campaigns directly from Google. |
| Campaign Import | Original campaigns built here. | Import Google campaigns in minutes. Then optimise for Microsoft audience. |
| ROAS | Benchmark: 3-6x for eCommerce. Higher volume but more competition. | Often higher ROAS than Google due to lower CPCs. 4-8x common. |
Our recommendation
Run both. Google Ads first for volume and primary revenue. Microsoft Ads second for incremental revenue at lower CPCs. Import your best-performing Google campaigns to Microsoft and optimise from there. Budget split: 80% Google, 20% Microsoft for most brands.
Pick Google Ads if...
Always run Google Ads for eCommerce. It is the primary search channel with the most volume.
Pick Microsoft Ads if...
Add Microsoft Ads once Google is profitable. The import feature makes setup quick. Lower CPCs mean higher ROAS on incremental spend.
