how to know the percentage of traffic that comes from yahoo to one’s website

how do I know how much percentage of traffic that is coming from Yahoo and which method increase my website traffic?

Google analytic is a perfect tool to be used. How it works is that it gives you the account of how many traffic that has come to your website per day. The website which the visitor came entered your website whether the visitor entered directly or through search engines. With the Google analytic you can then determine the percentage of traffic that comes to your website from Yahoo
