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.
