Almost not more than 45%, but its depend on your website, relevant niche answers and how popular are you in yahoo answers.
My clints sites which are mainly online stores average 15% from Yahoo! My semi-personal site (which I haven't optimised for, or even submitted by me to a search engine) has not had a single visit from Yahoo! Out of my ~1000 UV a day, just 200 of them come from search engines - either Google, Google Images or Yandex.
Depends on the site, the niche, the ranking... etc. I have sites pulling close to 20% from Yahoo. Just because you only pull 2% means absolutely nothing. Everybody who has been trying to market anything online realizes that Google Gets more views than Yahoo. Surprisingly FACEBOOK pulls more eyeballs than Google. So what do you do with this information?
I get 20% from Yahoo but I haven't done anything for Yahoo but tried a lots for Google. And this is my first time that I get so much visitor from Yahoo. so, I too think it's useless to discuss on such topic.
Actually i've not measured it for my website Do you have any idea to measure what % i'm getting traffics from where??
Very less, probably 1-2% only. Google brings in the gaint share of my traffic, probably around 90-95%
I get about 10% from Yahoo! I think that the longer your site has been around the more your traffic will increase from Yahoo because they just take a while to first index sites, and second have sites raise in their search engines. You will notice that most of the sites that are high up in the search engines in Yahoo have been around for a while. This is what I have found at least.
