Remember that phrase by Will Rogers? What first impression are you giving with your profile picture on your social media sites? In my opinion it is wise to use a professional photo (the same one) across all of your profiles. For many business owners, we are our brand. Many people know my name better than they know the name of my business, Cannon Social Media Solutions. If someone was going to look me up via social media, if they put in Vicki Cannon or Vicki S. Cannon, they will know that they got the right person if they have met me before, because my photo looks like me. If the person has not met me, but is going to meet me in a public place, they would be able to see my profile picture and know who to be looking for.
