There are a few things to consider when choosing your online avatar. While this seems like a simple task that doesn’t require much thought, it is actually something that should give you pause.
The first thing to consider is that people trust logos and brand images/trade dress. Its why companies will pay millions of dollars to defend their trade dress against copy cats. So if you have a trusted brand, and or a well known logo, you may want to use your logo. However, that being said you will be viewed as a corporate entity. If that’s okay with you, go ahead and use the company logo. If you want to be see more personally, use something different.
You can use a photo of yourself. However, people don’t know you personally and may feel you are not really representing the company you work for. While they may want to believe there is a “real person” answering their questions and addressing their concerns, they want to know that its someone they trust.
You can also use something completely different. For example you can use an avatar that represents a hobby, something your company likes or even an artistic rendering. Again, people online may not know what this relates to you or your company and may ignore what you have to say.
Regardless of what you choose, monitor your followers, and see what they have to say about it. If you change your avatar, monitor the rate at which you are acquiring followers. If it changes, people may no longer be sure its “you.”
