Frequently Asked Questions
Why should I use the same username across all platforms?
Using a consistent username across all platforms makes it easier for people to find and recognize your brand. It builds trust, improves discoverability, and creates a cohesive online identity. When someone follows you on one platform, they can quickly find you on others.
What makes a good social media username?
A good username is short (3-15 characters), easy to spell and pronounce, consistent across platforms, and free of special characters. It should be memorable, reflect your brand or personality, and ideally match your real name or business name.
What should I do if my desired username is taken?
If your username is taken, try adding a prefix like "the" or "real", a suffix like "official" or "hq", or use underscores to separate words. You can also try abbreviations of your name. The key is to keep it recognizable and easy to remember.
