Make your background image a billboard to say what you and to brag a little. Get rid of the dog photos and family photos. This is not Facebook. I wrote a step-by-step guide with many examples on how to create a background image that works. You can just follow the steps and do it yourself or hire it out for a cost of $50 – $100. This is the simplest, fastest and most effective change you can make in your LinkedIn profile. As noted above this is an example of “value add”.
