Raking is not Everything!

hi,

My site is ranking for all top and competetive keywords. in Google.
But not able to increase traffic fastly for my site.

Most of the traffic is comming through MSN. As PPC is running for some keywords. But, not ranking in Natural SEO for those keywords in top 10.

We have made seperate page for those keywords but the page which is comming in MSN ranking is the index page. if I will change some text in index page to get ranking in MSN. It might affect our ranking in Google. I don't want to take any risk.

Pls, tell methods :

1) ranking in MSN.no.
2) various methods that can be implemented to drive more traffic / visitors towards site, other than ranking and PPC.


Thanks in Advance.
