Not able to Create custom URLfor my Business page
Re: Not able to Create custom URLfor my Business page
Note: not all local listings get an offer for a custom URL
See more in here
They tell us there:
To get a custom URL, your account needs to be in good standing and meet a few other requirements.
For Google My Business listings: Must be a verified local business
Guessing - but not sure - in your case the domain name as GMB name triggers not getting an offer as described in here: https://support.google.com/business/answer/6068603?hl=en
Note your business in named as "sellback" using as GMB name "sellback.in" violates their guidelines - you can't expect Google consider this "a good standing"
