Merely being on a social media site is not enough. It takes time, effort and a lot of trial and error to discover just what the best sites are for your business. Don’t even start to use them if you are not going to at least give it your best.
But what we say is do try them all! You might not instantly become a social media and digital marketing expert, but at the very worst you have tried them for a few posts and then decided it is not working for you. But those posts will still remain and you will at least get a backlink out of them! A win win even if nothing comes of it.
