I am staring to get a trickle of vistors from Yahoo, but my rankings are much better in Google. Why is this? Usually, the level of competing sites for any keyword on Yahoo is almost half as Google, so why is it more difficult to rank high. If I start ranking on Yahoo for the same keywords and similar positions as Google, my traffic would almost double as I would be getting traffic from both.
Also, Yahoo has only indexed about 50% of my pages compared to Google's 95% and MSN's 100%.
