Yahoo and Bing? Do you care?

Personally speaking I optimize my pages for Google and build backlinks for all search engines. I don't necessarily target strategies within these "lesser" search engines, but I know building quality backlinks in strategic ways will solve this very easily. This also includes ASK & Altavista plus other search engine directories that don't pull as much weight as Google in today's current market.

Focus on google and you should rank easily with some of the other ones, I have had sites that didn't get where I wanted to rank in google but they got ranked on some of the other ones, so focus on google and the others will come.

I never care yahoo or bing. It's only google!!!!

I have sites that rank #1 on yahoo but are not even on page 1 on Google for the same keyword search. So I would say focus on Google and the rest will just follow.

I never think about any one particular search engine. I work thinking about Google and it also works for every others.

I would say that I focus on Google, but I definitely pay attention to Bing/Yahoo as well. In general, if you rank well in Google then Bing and Yahoo will follow. When you read the ranking guidelines for Bing/Yahoo, they seem to be where Google was a year or two ago which is why your rankings may not line up.

For example, I don't believe that Bing/Yahoo take into account the nofollow tag. However, if your overall SEO strategy is strong, it will work out for all three eventually.

Prefer Organic and here's why (Based on my experience)

Google
Have run PPC in Adwords with a help of a qualified Adwords manager who i still have For my PPc Campaigns when i use Google But I have more great experience rolling up my sleeves and getting offline SEO and ONline SEo sorted out Recently such as Article marketing, Backlink and press releases which 2 of my sites have sat on Page one for quite some time for all the hard work. As matt curtis had recently said it is about quantity not quality. When i have ran Campaigns on ppc my budject has been varied and well...Exhusted before i even hit page one sometime and that is why i am a firm Beleiver now in Organic methods.

Bing&yahoo

There has been talks of bing and yahoo having a dominat share but to be honest i have never used any of them because Yahoo's own PPC is Quick daunting because of payment terms(Adding your credit cared before you placed your campagn up and running) While Google is just standard set up your adverts and post pay billing which makes more easy to run capaigns and split test.

Hope that helps

Yahoo/bing have almost the same searching structure some of my websites are doing good on these search engines but still struggling on google.

Google is holding 65-70% of search market share, then why would you care for the rest 30% which is being shared by Yahoo, Bing, Ask and AOL. So targeting one search engine (Google) will benefit.

I never optimized, even never thought of optimizing my sites for Yahoo or Bing, like other people I am targeting Google and my sites rankings improving in Yahoo and Bing as well.

I would focus on Google because from what I see on my sites analytics 85% of SEO traffic comes from Google. You have to apply the 80/20 Rule and like other guys are saying if you do proper SEO work in Google it will oftwn spill down to Yahoo and Bing.

For Bing:
Remember to submit your sites with their webmaster tools to get your site noticed

Google all the way. But if you have competitive keywords already ranking on Bing or Yahoo's SERP's top page, then better take advantage of it and try to reach the top 3 spots, given that they can still do generate relevant traffic.
