A year ago, I would have told you that it was really important that you have a Facebook page for your business or blog. But times have changed and getting your message across to your target audience through social media has become more difficult than ever.
Even if you come up with impressive marketing campaigns, fans of your business page may never even see them due to Facebook's always changing algorithms. You'll have to include some promoted posts and ads into your budget spend to reach those fans, that you should be able to reach organically. Let's face it, Facebook was eventually going to figure out a revenue generating concept that went further than basic ads popping up in your newsfeed but, the question now is: Is Facebook really worth it?
Even if you put your spend into targeted adverts, sponsored posts etc - the amount of work, time and money that is involved might not be worth the effort. Other platforms are outperforming Facebook now on conversion rates, with Pinterest moving to the top of the line.
My advice here would be to weigh up the amount of time and money you are able to invest in getting your Facebook page up and running. If the pros outweigh the cons, then sign-up and go for it. Otherwise, take a look in another direction. After all, you want to make sure that your target market will see your carefully put together blog posts because there's a chance that Facebook will leave you guessing, and guessing might just be where you will stay.
