When adding a site to mlytics, the system will ask your 'Site Domain Name'.
It depends on which URL/domain is mainly used by your site. Let’s say you’re using “www.test.com”, then you should enter “www.test.com” in the “Site Domain Name” field.
|Main domain||"Site Domain Name"|
In this case, all website resources URL path is based on this e.g. www.test.com/img/123.jpg
Why this matter
Once you have added a site, mlytics will assign a unique CNAME for your site. You will have to add a CNAME record with this assigned CNAME via your DNS provider.
When doing so, it is critical to fill the "Host" field with the EXACT same domain as the "Site Domain Name" you've entered when creating a site via mlytics.
