PV from different search engine is not equal, why?

i use keyword optimize to get more pageview, but i was little confused about the result.

The PV from different search engine have big differences. e.g.
Google=220,
Bing=9,
yahoo=5,
search=2
aol=1
...

why so big differences? what is the factor?

 

Google is the most popular search engine so alot of your views would come from that.

 

Google search has high amount of users and no search engine is close to it competiton wise so thats why its like dat

 

The big difference is that almost everyone uses google for search.

 

What is the 'Keyword optimize' you use ?
Is it a tool or something about 'keyword density' ?

 

All other search engine are slow indexing. I am facing the same problem

 

i try many ways to improve the PV of yahoo, it is useful.

I didi:
submit my website to the yahoo;
use the yahoo answer to submit my link;

you can try!

 

Google go for page rank and Yahoo looks for inlinks to your site. So both are different and yahoo is slow too.

 

use google keyword optimizer to get faster results!

 

yahoo take care inlinks? i never know this, i will try to manage the inlinks to see whether it is useful.
thanks
