I like to use a combination of all 3. Google plus is on the rise and is the place for "intelligent comment". Facebook is the most popular at the moment. And Twitter – well, you can just send a tweet off whenever you post to the other 2 in 2 seconds, so why not?
Many social network are avaliable. Rating No 1. Facebook 2. Twitter 3. Linkedin 4. Pinetrest 4. Google Plus 5. Tumblr 6. Instragram 7. Vk I belive twiter is the best for seo. Twitter is the most popular micro blogging platform as of today . Twitter is a large network and has the potential to supplement your SEO activities .
This is kind of a broad question the way you asked it. Currently, if you are looking for volume and traffic I would think that Facebook is your best bet. Currently, I have accounts on all three major names (Facebook, Google+, and Twitter). I definitely utilize Facebook more than the other two, but it isn't because I'm a fan of it; it's just where all my family and friends are. Personally I like the UI and Functionality of Google+ and have been trying to use it more, but I do not have many colleagues or friends and family that utilize it as much as they do Facebook. Hopefully things will shift as an older crowd continues to take over Facebook and drive the younger users to Google+ or something else in the future.
all together are making good job. Good social rank and good way to find new visitors to website. All are good for adverts and marketing. All together working are making good SEO
With respect to age and gender, Facebook is probably closest to the general population. Other social network tend to be younger, more male or more female -- without getting too specific...
it depends on your using intension. if you want to use for chatting, checking out or something like that then facebook is the best choice. but if you want to grow your business, sells and marketing then you should definitely use google+ right now.
why you don't target all three social networks. Every social network have its own importance. You can find on which social network your audience is hanging try to focus that social network.
There's a prevailing opinion going around that Google+ is better for SEO and that Twitter is better for audience engagement, and I agree with both. My opinion is that it's time to start ignoring Facebook. I might be alone in thinking this, but Facebook is no longer the advertising tool it used to be. Whatever improvements they pretend to make for advertisers and their users, the only thing that's really happening is that more and more people are getting annoyed by the website.
Akash47 is right, with all the new advertising rules of facebook, it is getting harder and harder to attract traffic on your page. And google + is aware of this that is the reason why they are doing something to pull people out of facebook and move to google +.
I like to use all three, but they all have their own ups and downs. It seems that originally getting followers on Google+ required more effort that on two others. However, with recent changes, Facebook is becoming less and less useful unless your are willing to pay them for advertising.
Someone out there uses either of those social networking sites so I think it depends more on people's preference. Since I use facebook more than twitter and google+, well then for me facebook is the best.
