Here’s a strategy for 2013.
Slowly go through your social networks, blogs and other mediums where you’ve produced content and start clicking delete on the bad stuff.
The pieces that are badly thought out, don’t offer any real value or show your best work. Anything below your standard should be cut. Any content that you don’t want your clients to see.
A great place to start is Googling yourself or your brand and finding the ugly content. Maybe it’s something you produced give years ago when you weren’t as good at righting as you are now. Or maybe it’s a point of view that you’ve changed since.
