Typing link:site.com into Yahoo! shows me a huge amount of backlinks from a wide variety of domains. Typing link:site.com into Google shows me a very small selection of backlinks, most from just a handful of domains (no idea why). Now I know that Google backlinks spit out completely old data that is just a "sampling" of the links Google knows about. But what are the chances that Google actually knows about / counts all of the links that Yahoo does? My reason for asking is that Google sends me a LOT of traffic and Yahoo sends me absolutely no traffic (Less than 1% of what Google does).
Is it possible to get a decent amount of traffic from Yahoo? Everything points to them thinking that my site is completely worthwhile, I do a lot of on and off page SEO, and yet traffic from them is really pitiful.
