No, you do not have to create goals. However, in order to get the real value of SearchAds.com, you need to track how much you spend on a specific keyword and what is the ROAS%.
That is why we recommend you to create goals and track your selected goal/s for your apps.
In addition to tracking your ROAS, creating Goals will also enable you to create Automation based on your goal to take automatic actions when store dynamics change.
Important: If you did not integrate any MMP partner or custom solution, you will not be able to create a Goal. Please check our Partner Integration posts for detailed explanation.
