In Italy most of internet users use google for search the web, they also type in google the url of the website... lol
Interesting. I've noticed my Yahoo traffic converting better as well. I will receive a ton of traffic from Google but the conversion rate is much much lower.
According to me Google will get more traffic than the Yahoo because the Google Has lot of users and also the best search engine where gets more traffic than the Yahoo.
The Traffic of all Search Engines are Genuine. The Visitor will stand or stay on your website according your web pages content, design, If your website have informative content, information, Accurate knowledge, then visitor will stay on your website. If you have low quality Content or no informative, Then visitor close your website immediately...
