Marketo Measure Cookies marketo-measure-cookies
Learn about the various Marketo Measure Cookies that are loaded onto your site when you apply the Marketo Measure JavaScript to your landing pages. This information may serve as useful for the web development team during implementation.
IMPORTANT
Due to privacy concerns, third-party cookies are on the way out. Google Chrome’s announced Q3 2024 deprecation of third-party cookies effectively marks the end of this form of tracking. As a result, Adobe is deprecating Marketo Measure functions which rely on third-party cookies; specifically, Cross-Domain Tracking and View-through Attribution, which use the Google/DoubleClick impression cookie. No other functions of Marketo Measure will be impacted. First-party cookie usage is also not impacted. In light of Google’s schedule, the expected deprecation date for the two functions above is 6/1/2024. Related data collected before this date remains available to Adobe customers.
