A good profile picture is a great first step. However, for the world of wrestling we need to qualify what that is.
These things that we're about to mention do not apply to established talent, bookers, promoters, or trainers who may use their profile pictures to promote events or companies. We're specifically talking to those making their way as a wrestler.
The picture should be clear, well lit, and proportional. Your face and shoulders should be taking up at least 50% of the frame. If you can see your feet in the picture then you're doing it wrong. No far-back picture of you standing by the Lincoln Memorial.
This should go without saying, but your profile picture should be of YOU. If you are part of a tag team that's cool. But maybe avoid the duo picture. Have a sweet shot of you landing a clothesline on an opponent? That would make a good photo for your timeline but not your profile picture. Most of all avoid group photos. When people search for you they want to know that they've found you. That's hard to do in a group photo.
Don't be afraid to spend money on a head shot. But even if you can't do that have a friend help you get a good picture. We all know someone that is a hobby photographer. Next time you're around them ask them to take a good photo of you.
Get rid of offensive material. No middle finger, no offensive shirts, and no drink in your hand. Scan back to old profile pictures from the last ten years (because other people will scope them out). Delete any that would give someone the wrong idea about you.
Finally, do some research on how to do a good profile picture (YouTube has great videos). Remember all of the standard tricks. If it isn't blinding you it's better to have the sun in your face rather than behind you or directly overhead. If you're taking a selfie NEVER look down at the camera. Hold the camera at least slightly above eye level.
Your face IS your brand until you are big enough to use something else as your brand. When people have a clear picture they feel like they can connect.
Here is one final red hot tip. If you have taken a few good profile pictures over the years do a post and ask your followers and friends to help you pick the best one!
