We buy lots of ads
I’ve always known that eBay buys lots of pay-per-click ads, but here are the numbers to prove it.
Not only is eBay #1 by a long margin, we just closed the deal last month to buy up #2 Shopping.com. Combined we buy over 5x more than the next closest company, IAC. That’s a lot of ads.
