Pay attention to the quality of your profile picture. A razor-sharp image with good exposure and contrast looks more professional and appealing. Avoid blurry or pixelated images as they will make your profile appear less attractive.
It's a good idea to change your profile picture from time to time. This shows freshness and keeps your profile interesting for your followers. You can customize your profile picture to reflect special occasions or seasonal changes.
Your profile picture should be easily recognizable, even in low resolution. Don't use overly complex images or those with too much detail. A simple and memorable image that relates to your brand is ideal.
