There has been a lot of rubbish on the blogosphere over the last couple of weeks about how in the near future we will see which will be the more dominant in online marketing: either traditional
Search Engine Optimisation [mainly getting links from good websites] or Social Media [not just FB & Twitter, but so much more] will be the winner. I am opinionated, granted, but could both sides please shut up! This is the same thing as the old 'SEO is dead' argument, just with different wording.
The simple fact is that nearly all of these social media sites give you at least one link on
your profile, google indexes it and it feeds into its algorithm [SEO, no?]. On the other hand there is more interaction on Social Media which might help for your link/content/whatever to be shared/liked/retweeted/whatever. Most SEOs are so beyond google's Toolbar PageRank that they understand that you can get traffic to a site though many means [and I am not including
mechanical turk in those methods, though that can work if you want to impress a client, however without any meaningful results], and that you should use all that are available.
I don't think I am saying anything incredibly ground breaking, from various searches it has already been shown that google reads through bit.ly links on twitter, and I can see no reason why this should not be the case with all the reputable shorteners, everybody in the game knows that nofollowed links can still pass anchor text value, so nofollowed links on important sites such as wikipedia, knol.google.com [though that is soon to be deceased], yahoo [and even twitter] are still relevant. What is more, links on major sites bring more clickthrough.
Besides as I said before, any good SEO could get a link out of most social media sites, it is your job after all....
Did you get what I am saying, it is all on the internet............. [now marketing for mobiles, that is a different thing all together]
