Efficient Frontier has released data showing where those paid search click referrals are coming from. Here’s the raw data:

Yahoo: 45% from pure search, the rest from its 1196 syndicated sites
Google: 59% from pure search, the rest from its 431 syndicated sites
MSN: 99% from pure search, the rest from its 5 syndicated sites

But when it comes to conversions, pure search beat out syndicated sites every time:

Yahoo: 58% from pure search
Google: 75% from pure search
MSN: 100% from pure search
