Tips for Choosing a Great Username
- Keep it under 15 characters — shorter handles are easier to remember and fit all platforms
- Avoid special characters — stick to letters, numbers, and underscores for maximum compatibility
- Make it memorable and brand-relevant — your username should reflect who you are or what you do
- Check for trademark conflicts — avoid names that could cause legal issues down the line
- Consider SEO — including a niche keyword (e.g., "janefitness") can boost discoverability
Why a Consistent Username Matters
Your social media username is the foundation of your online identity. When you use the same handle across Instagram, TikTok, X, LinkedIn, YouTube, and other platforms, you create a unified brand that people recognize and trust.
A consistent username makes it significantly easier for your audience to find you. Whether someone discovers you on TikTok and wants to follow you on Instagram, or sees your content shared on X and looks you up on LinkedIn, the same handle eliminates friction.
Brand consistency also improves your SEO. Search engines associate your username with your content across platforms, strengthening your overall digital footprint. Use our cross-posting tools to maintain a cohesive presence everywhere.
How to Choose the Perfect Social Media Handle
Start with your brand name
Your username should be as close to your brand or personal name as possible. Simplicity wins.
Check availability first
Use this tool to verify your handle is free on all platforms before committing. Secure it quickly once confirmed.
Think long-term
Choose a name that can grow with you. Avoid trends that might feel dated in a year. Plan your content strategy around it.
Say it out loud
If you cannot easily say your username in conversation or on a podcast, it is too complicated. Keep it pronounceable.
What to Do If Your Username Is Taken
It is frustrating when your ideal handle is unavailable, but there are proven strategies to find a great alternative. Here are the most effective approaches used by successful brands and creators:
Try "the," "get," "try," or "its" before your name. Example: thejanesmith or getmybrand
Use "hq," "official," "co," or your location. Example: mybrandhq or janesmithnyc
Add underscores or periods between words (where allowed). Example: jane.smith or my_brand
Shorten longer words or use initials. Example: jsmith or mybrandco
Include what you do. Example: janefitness or branddesigns
If the account is inactive, some platforms allow you to claim it. Check each platform's trademark policies.
Once you secure your username, set up your profiles with our Instagram Bio Generator and TikTok Bio Generator, then start scheduling with PostEverywhere.
