That's completely incorrect. Google makes most of it's money off of adsense and advertising, and it does not at all correlate to it's search engine. I like some google features that are missing from yahoo, but google got popular due to gmail and shallow trendiness, nothing more. I use both, and yahoo gives me the most useful results easily. When there's something more obscure, I go to google, but google also packs a bunch of junk results.
I think google do index sites reasonably with organize criteria. But we can't deny the fact that a lot of prospect buyers or clients come from yahoo.
I would definitely say google. If you just do a quick search on Google and yahoo. You will find that google still is quite ahead from yahoo and has quite relevant search results as compared to google.
Surely Google. Though Yahoo is no 2, but it may be comes after 5,i.e. 1.Google, 2.Google, 3.Google, 4.Google, 5.Google, 6.Yahoo.
It depends on your target searchers. For the Philipppines, Yahoo is still the number one choice, not Google.
Aye, I have always got about 80/90% from Google, but Yahoo has always been minimal. I actually think Ask and MSN do a much better job.
I prefer using Google's Search Engine for my Searches. Ranking higher on Google would naturally seem more important to me that the same task on yahoo. I believe it is easier to rank on Yahoo than it is on Google. (For a new Website)
Definitely Google, they know what they are doing and I don't know if anyone can bet them any time soon.
