Having a custom URL is so much more SEO friendly and easier to search. YouTube has put in some minimal requirements in order to create a custom URL but we highly recommend you take the time to set it up for your channel.
- Account in good standing: Which you should be if you're in our network.
- At least 500 subs: Don't have enough? Start promoting your channel to friends and family and social media!
- Channel is at least 30 days old.
- Uploaded channel icon and art: If you're too lazy to do this, don't even bother about the URL.
