There is no THE BEST social site. Every of those sites have his own target. And choosing one of those depends of the people you want to reach.
Facebook would be the biggest right now, but that doesn't mean that it is necessarily the best for what you are trying to market. A lot of techies probably use Google+ for example.
I use all 3 facebook, twitter, google+. When it comes to seo friendly,twitter is more considered by google and so by me.Twitter has a higher page rank than Facebook and Google +. Google plus is looking promising and seo friendly as well now and has achieved a huge amount of users in a quick period of time. But Facebook has a different reputation.The all time entertainment.
I use Google+, Facebook, and Twitter all are best and good way for SEO but I mostly suggest to Facebook because it is most easy and valuable to generate high trafic.
Very tricky question mate, lolz..All three of them are very essential for Social media marketing, you can't say twitter is best or Facebook. you need to plan a campaign with the help of these all three, for better result.cheers!
I don't think that "which one is the best?" is the question to be asked. I'd rather ask "which one is more useful?". For me, facebook is still the first one on the list because i can chat with my friends that are abroad but i can also use it as a good way to advertise my blog. Secondly i use twitter when i don't need that much of a description. And last but not least google+. Even thou i got an invitation in the first days when they launched it, i still don't use it. I just keep adding and adding people but it didn't catch my interest.
Love Facebook 'cause all my friends are there. I don't know what we would do without it. Sometimes I forgot about my sidekiks, 'cause they are around the world, but remembering of them in a Facebook gives me confidence and I want every time to meet them.
Twitter is like an easy diary where you can vent out everything every minute. In Facebook, it's more of uhm, showing off everything about YOU and your life.. in short, reputation builder. Dunno if that even make sense.
