I have a seoer for a year, but really Yahoo is not in my favor. It is not easy to be pleased, and it has much low market share than Google. It only indexed my home page and still can't firgue out the problem. Right now, i mainly targeted on Google and Bing, i think it is enough. If Yahoo want to survive in the search engine industry, it has to make changes and do better.
I am not absolutely agree about this thread. Yahoo may a slow search engine than Google but as far as I know Yahoo has achieved the second position. I think this question is a irrelevant question. It seems to me that about 40% people visit Yahoo everyday.
No seo Method known works for Yahoo and Bing....I am testing one, earlier, it worked for me As i used many of Anchor text with same anchor test, and it kind of worked for me, but right now i am going for New website with unique no competition keyword and optimize for yahoo to see how it works out, i will keep informed.
Yahoo are still siginificant taking 7% of all searches. Obviously with Google being so successful (86%) that's the place to concentrate your resources. However if you segment is likely to use other engines they probably should also get some effort.
You just have to focus on Google and optimize your site in Google .... i assure you if you have a good ranking in Google then Yahoo will also let you come up on its ranking....
I think its better to use the Google as search engine then Yahoo in SEO. Because Google provide some strong search algorithms and some tools that are basically needed in SEO strategies
