Your social spaces should have as much of the same look and feel as your website. This is a lot easier to do with Twitter, but there are ways to make your Facebook page fall into line with your website.
Just like the rest of your marketing efforts, your social spaces should reflect the same level of consistency in appearance. Here’s an example:
If they don’t look the same – the first question should be “why”? In most cases, there hasn’t been enough attention placed on integrating the look and feel of these platforms. Social media has moved from an after-thought or value add space to a front/center position. So by now, if a teams’ social spaces do not share a consistent look it reads as sloppy or second class. The only reason that a teams’ social spaces do not share any consistency is because that is a part of a larger strategy at work.
