I like that it is easy to use for beginner users, as well has being able to have multiple accounts in one account at once which makes things easier when you're not logged into all of them separately but instead with just 1 login.
There isn't anything really bad about this software so far other than maybe if there was more advanced options available (like different ad groups) or something similar then i would say its worth trying out! You can easily set up campaigns using higher ads without having any kind of coding knowledge needed. Also since we are an agency our clients don’t always know how to code themselves and therefore give us their data/accounts etc. So by setting everything up ourselves through higherads saves time from going back and forth between client and developer.
