The following two tables provide a list of cookies that get dropped when you browse to an Eloqua tracked webpage -- whether it be an Eloqua landing page or an external webpage that has Eloqua Tracking scripts on it:

 

1) Strict-mode tracking is enabled:

CookiePurpose
ELQSITEVISITEDThis cookie has one single value "Yes". It is a session cookie and will be dropped and set to Yes when the webpage calls elqTrackPageViewDisplayOptInBannerByCountry or elqTrackPageViewDisplayOptInBannerForAll, so the strict-mode banner is only shown once during a session.
OPTOUTHas a value pair of s+siteid=1 or s+siteid=0. The purpose of this cookie is to store the client response to the opt-in prompt.
ELQCOUNTRYThis cookie has a value of all the countries that are subject to strict-mode tracking in the install
ELQSTATUSThis cookie gets dropped ONLY if the client consents to being tracked
ELOQUAThis cookie has a value pair of guid = randomly generated string of characters and numbers.

 

2) Standard tracking:

CookiePurpose
