What are the different pros and cons for Google, Yahoo and Bing? I only use Google but many of my friends use Bing. I'm just wondering if I'm potentially missing out on useful information that the Search Engine services can give by limiting myself to just using Google. Any insight?
I use a combination of search engines and generally the search results are very similar. I don't think you're missing much by just using Google. Are you able to find what you're looking for? That's what matters.
Actually Each search engine have different ranking criteria, which is unknown to the outer world like us. Searchers usually use search engines to extract information. All to see , how much users are depending on which search engine, For time being Google is dominating, As a result, Every body is rushing to rank up high in Google SERPs. There is no such Pros and Cons of search Engines..But I must say each search engine have only pros, they don't have cons.
for now, google is obviously the biggest search engine, so I would say 90-95% of your efforts should go to google. BUT if some day, some search engine becomes more populard worldwide, than you may want to change that ratio for example I, myself only care for google for now
