Yes, you can white-label a Google My Business Audit for both the PDF & External URL reports. White-label reporting is only available to customers on Multi-Business and SEO Pro packages.
In the Admin Console, you can create a ‘White-Label Profile‘ and upload your own logo, select font colors and add additional text in order to customize your Google My Business Audit reports. You can create multiple White-label Profiles if you need to and can specify which reports should have which Branding on them (great if you provide white-label SEO services).
To find out more about white-labeling and to help to get started check out this area of our Help Center.
