Safari FAQ

Can Safari users be tracked by third-party cookies?
No – by default, Safari blocks third-party cookies, such as Salesforce Audience Studio. However, first-party cookies can be used to track Safari users. We recommend using server-side techniques to set first-party cookies and configuring the Audience Studio Control Tag to read these cookies.

Can I target audiences across Safari using DFP?
Yes - DFP can target audiences across Safari but only if the segment IDs are sent to DFP using the key-value method. Please note that the S2S method will not work on Safari. More information on sending key-values to DFP can be found here.

Can you build segments from Safari users?
Yes, for analysis.

Why my segment doesn't show Safari devices under 'Breakdown by device types'?
The Safari device count might be too small, so it gets hidden in the bar chart. But you can zoom in on any portion of the graph to see them by dragging the mouse to the left near the Safari icon.

What solutions does Audience Studio support in order to track users on Safari browsers?
Audience Studio offers two options to track users on Safari browsers:

1. First-party cookies, set and managed by the customer.
2. First-party cookies, set and managed by Audience Studio.

How time-consuming is it to enable the two solutions?
First-party cookies managed by the customer require development work on the customer side, and thus, timing will be dependent on their completion. Once the customer has set up the first-party ID, enabling it on Audience Studio's side is reasonably quick as well.

The work to enable first-party cookies managed by Audience Studio is done by Salesforce and should be relatively quick to enable for a customer.

What’s the difference in how the KUID is created in the two approaches?
First-party cookies managed by the customer sets the KUID to be the identifier that is associated with the first-party cookie. First-party cookies managed by Audience Studio generates a KUID.

Can you use Google PPID as a first-party ID for Safari?
Yes, but the customer must first work with Google to enable PPID for their Google account. The customer needs to provide Salesforce with the Google cloud storage location for uploading the user lists.

Additional information is available on Google’s support pages.

How do first-party cookies handle opt-outs?
If the customer is utilizing a first-party cookie and has multiple domains, a dedicated opt-out will need to be configured and maintained for each site. 

Do both approaches lose users when cookies are cleared?
Yes, first-party cookies can be cleared.

Can you user-match with third-party data providers when utilizing a first-party cookie?
Customers will issue a first-party cookie to Audience Studio, which we then take as our ID. Since it's not a third-party cookie – even though we are acting as an agent of our customers – it means that we are unable to sync those users with a 3rd-party data provider unless the 3rd-party fires a match pixel.

Does Audience Studio support fingerprinting on Safari?
Fingerprinting is deprecated effective May 2019.
