Yes it is but i wouldn't mainly focus on Yahoo since the traffic you could get out of it compared to Google, Facebook, etc won't be higher.
yes, i get traffic from yahoo after google recent updates. so it is important to get traffic that is not only controled by google.
yes Yahoo is good on its way but users are more relieble on Google so a host you have to give more priority to Google.
I get probably less than 1/20 th of Google traffic from other Search engines. Google is the leader big time.
Every search engine is 'good' some better than others,the more search engines that your sites are in the wider audiance you have so having your site in Baidu and Yandex are good as well.
As the market share of total search market is low for yahoo compared with Google, the SEO in Yahoo is not much attractive one. But, you can work to capture the market as the amount of competitor in Yahoo SEO is also low.
Google is the #1 for SEO. If you are doing good SEO for Google than you should naturally rank high on Yahoo or rather Bing's engine.
Well you can't just ignore Yahoo as far as the SEO is concerned. Though it is lagging much behind than Google but it does matter when it comes to organic traffic especially from some certain locations like US and UK.
From my point of view Google is the best search engine. Google is easy to use and yahoo is not more user oriented. I prefer Google for searching anything and I get the best results from it. GOOGLE is the King.
Yahoo is the best and Good search engine but it does not give many answers than in Google in which Google will provide more answers than the Yahoo but yahoo will have best answers.
Yes of-course the yahoo is the best search engine for SEO, it doesn't mean i am against Google. Besides Google, Yahoo is the Second best search engine.
I don't feel Yahoo is good search engine for any type of marketing ,your search result is not good as compare with Google,I feel Google have no competition in presence of Google you not need to try any other .
Yes in my view Yahoo is the best SEO for getting accurate search results but not so popular than the Google.
