It is a good idea to have all your domain URLs at one company, for example, GoDaddy.
In this way you can keep a list of all your URLs in one place – on your GoDaddy Account or whatever Registrar you are using.
In this way you can regularly review all your websites keep track of underperforming sites.
It is also a good idea to make sure you don’t have automatic renewal turned on for your inactive or underperforming sites. In this way you will get a notice of when it is time to renew these sites and you can decide whether or not you want to renew.
On GoDaddy you will sign into your account and then go to Domains. You will have to click on each URL individually in your list to turn off automatic extension (at GoDaddy at least).
