# Cookies and Activity Tracking

Account Engagement tracks visitor and prospect activities on your website and landing pages by setting cookies on their browsers. Cookies are set to remember preferences (like form field values) when a visitor returns to your site. We also set a cookie for logged-in users to maintain the session and remember table filters.

Account Engagement sets first-party cookies for tracking purposes and sets third-party cookies for redundancy. Using first-party and third-party cookies together is standard in the marketing automation industry. We don’t store personally identifying information, only a unique identifier. First-party cookies are set on Account Engagement domains and tracker subdomains. If you don’t have a tracker subdomain configured, we use third-party cookies on HTTPS pages.

To ask visitors to consent to tracking [enable tracking opt-in preferences](https://help.salesforce.com/s/articleView?id=mktg.pardot_admin_tracking_opt_in.htm&release=264.0.0&type=5 "You can request that visitors opt in to tracking. When tracking opt-in is enabled, new visitors are asked to consent to tracking cookies. The message doesn’t appear again unless they clear their cookies. If a prospect hasn’t opted in, page views and form views aren’t tracked. Email link clicks and form submissions still appear in their activity history.").

Note Pardot is now known as Marketing Cloud Account Engagement. We wish we could snap our fingers to update the name everywhere, but you can expect to see the previous name in a few places until we replace it, including in the app itself.

 
| Name | Details |
| --- | --- |
| visitor\_id<accountid> | The visitor cookie includes a unique visitor ID and the unique identifier for your business unit. For example, the cookie name visitor\_id12345 stores the visitor ID 1010101010. The account identifier, 12345, makes sure that the visitor is tracked on the correct business unit. The visitor value is the visitor\_id in your business unit. This cookie is set for visitors by the Account Engagement tracking code. |
| pi\_opt\_in<accountid> | If Tracking Opt-in preferences is enabled, the pi\_opt\_in cookie is set with a `true` or `false` value when the visitor opts in or out of tracking. If a visitor opts in, the value is set to `true`, and the visitor is cookied and tracked. If the visitor opts out or ignores the opt-in banner, the opt-in cookie value is set to `false`. The visitor cookie is disabled, and the visitor isn’t tracked. |
| visitor\_id<accountid>-hash | The visitor hash cookie contains the account ID and stores a unique hash. For example, the cookie name visitor\_id12345-hash stores the hash “855c3697d9979e78ac404c4ba2c66533”, and the account ID is 12345. This cookie is a security measure to make sure that a malicious user can’t fake a visitor and access corresponding prospect information. |
| lpv<accountid> | This LPV cookie is set to keep us from tracking multiple page views on a single asset over a 30-minute session. For example, if a visitor reloads a landing page several times over a 30-minute period, this cookie keeps each reload from being tracked as a page view. |
| pardot | A session cookie named `pardot` is set in your browser while you’re logged in as a user or when a visitor accesses a form, landing page, or page with Account Engagement tracking code. The cookie denotes an active session and isn’t used for tracking. |
