Is a 20 letter domain too long?

I personally don't want to type 20 letters in my browser haha

 

Yes, it have to be 6 to 8 letters.

 

A 20-character domain is a bit on the longer side, but it’s not necessarily a deal-breaker. The key is whether it’s easy to remember, pronounce, and spell. If the name is catchy and relevant to your brand, people will still find it. Just keep in mind that shorter domains are generally easier to share and type, so if possible, try to keep it concise while still reflecting your business

 

For the lead generating site no.
For brand, yes.

 

If possible, keep your domain name below 20 characters
