Website compliance and cookie consent notice implementation is no easy task. From beacons to pixels, AdTech, piggybacking, tag manager and everything in between, organizations can become overwhelmed with where to begin. Lucky for you, OneTrust Cookie Consent and Website Scanning is the most mature and trusted solution for cookie consent in the market.

The tool constantly scans your website for cookies and tracking technologies and auto-categorizes these technologies into consent groups by mapping to CookiepediaTM, a database of over 11 million pre-categorized technologies. Once the cookies are categorized, it is easy to customize your consent model(s) to determine which groups of cookies are loaded by default vs. blocked by default.

We’ll walk you through an easy step-by-step process to set up your consent notice and auto-block cookies in order to reach true compliance.

Step 1: Consent Notice

The CNIL, ICO, EDPB, Irish DPC—each regulator provides different recommendations and guidance for how to show consent, what text needs to be displayed, and how cookies on your website should behave based on the location the visitor is coming from. With so many regulations already, and new ones being implemented and updated, it can be challenging to keep up with the latest cookie obligations. Further, since websites are largely available globally, making sure your website is fully compliant is an intimidating task.

OneTrust PreferenceChoice’s Cookie Consent and Website Scanning Technology simplifies the process with our built-in Country and State Specific Guidance that helps ensure you create a consent notice that is compliant with various cookie consent requirements across the globe.

Not only do we provide guidance, we make it easy to implement using our Consent by Geolocation feature that auto-identifies the location of the website visitor and applies the correct consent notice and behavior based on the visitor’s current location.

For example, simply add PreferenceChoice Cookie Consent and Website Scanning to your website, and the functionality of your consent notice will automatically update to display a CCPA-compliant consent notice to a visitor in Los Angeles, and a consent notice in compliance with ePrivacy and GDPR to a visitor in London.

Here are the steps to add a cookie notice to your website:

  1. Scan for cookies and tracking technologies.
  2. Auto-categorize scan results with Cookiepedia – our database of over 11 million cookies.
  3. Style consent notice. Update the colors, logo, layout and behaviors using our easy-to-use design center.
  4. Customize consent model(s). You can use several models at the same time for visitors in different regions using OneTrust’s Consent by Geolocation feature.
  5. Add the OneTrust Cookie Consent and Website Scanning script to your website.

Step 2: Block Cookies

According to several compliance regulations, consent is not required for Strictly Necessary cookies, or cookies related to the functionality of a website. All other cookies, such as third-party or performance cookies, must be blocked until the visitor accepts the consent notice.

Using the automated categorizations from our scan results, we have several ways to block entire groups of cookies:


This method is the easiest to use by using OneTrust’s Auto-Blocking technology. Simply add the script onto your site and auto-block all key tracking technologies that are not categorized as Strictly Necessary until the user has provided consent. We have defined a list of the most common trackers (Google Analytics, Facebook, LinkedIn, etc.) and auto-block these scripts from loading based on how you have categorized your cookies and your chosen consent model(s).

Tag Manager Integrations

Using Google Tag Manger or Adobe Dynamic Tag Manager, simply create triggers in your tag management solution that only fire tags that set cookies if that category of cookies is accepted.

JavaScript Wrapper

Update the existing scripts on your website with our JavaScript Wrapper that adds a group identifier to ensure those cookies are not fired until the visitor accepts that group of cookies.
