How To Dynamically Block Ad Types Using data-blocked-types

As a publisher, you may want to control which types of ads are shown to your visitors based on specific conditions like user authentication, user preference settings, or other factors. In this article, we demonstrate two code snippets of how you can dynamically manage which ad types are displayed or blocked within your ExoClick ad zone.

To make this possible, we are taking advantage of ExoClick's data-blocked-type feature, and we’re giving it dynamic control over multiple ad spots without requiring complex backend integrations.

EXAMPLE 1 - Dynamically display ads based on user input​

This method is ideal for adjusting ad restrictions based on user consent. When a visitor agrees to your terms, their preference is stored in their browser's localStorage. This action permanently modifies the ad settings for that user on all subsequent visits, allowing you to serve a broader range of ad types once consent is given.

    <!-- MUST BE PLACED AFTER THE AD ZONES' SCRIPTS -->
    <script>
      const cookie = localStorage.getItem("acceptTerms");
      const parsedCookie = JSON.parse(cookie)
      if (parsedCookie === true) {
        updateAdRestrictions(true);
        document.getElementById("accept-terms-button").remove();
      } 
    </script>
  </body>

EXAMPLE 2 - Dynamically display ads based on URL parameter​

This approach is effective for altering ad settings based on a URL parameter. For instance, after a user authenticates, they can be redirected to a URL containing a parameter such as ?user_verified=1. This parameter signals to the page that the user is verified, prompting the system to display less restrictive ad types for that session.
