Data collection and storage for LinkedIn Matched Audiences

When you use Matched Audiences, we implement security safeguards designed to protect your data.

Website retargeting

For website retargeting:

Your data is stored in the LinkedIn data center.
The LinkedIn Insight Tag drops a cookie on your visitors' web browsers when they visit your website. Cookie information is matched against LinkedIn’s member account data to build your audience. Direct identifiers are removed from this data within seven days, and the data is deleted at 180 days.
An anonymous segment of matched LinkedIn member accounts becomes available for targeting within your Campaign Manager advertising account once the audience segment reaches at least 300 member accounts.
Matched LinkedIn member accounts are deleted on a rolling basis. The time until deletion depends on the time range of engagement you chose when you created your segment (between 30 and 180 days). Your audience segment won't include any LinkedIn member accounts whose last visit to your website was more than the number of days specified in your segment.

Important to know

Consistent with our terms, the Insight Tag should not be installed on web pages that collect or contain Sensitive Data. This can include pages offering specific health-related or financial services or products to consumers.

For example, depending on the content of the pages, the Insight Tag may be included on a generic homepage for a pharmacy or a bank, or business-to-business pages directed only to organizations and financial or healthcare professionals, but should not be included on consumer pages for certain types of medications or pages where users manage their financial accounts and transactions or medical appointments, since it could lead to the inadvertent collection and sharing of sensitive information regarding the health or finances of individuals who visited that page.

This does not constitute legal advice. Please consult with your webmaster and legal counsel to determine which pages may or may not collect sensitive data.
