OneTrust is primarily known as a consent management platform, letting you easily handle the endless cookie compliance hurdles that come from different regulations around the world. If you’ve got a website serving users across Europe, the US, or elsewhere, you can spin up region-specific rules so you’re only firing the analytics and marketing tags you’re actually allowed to. It’s basically like a traffic controller for all your tags: you set up categories such as “Advertising” or “Analytics,” and OneTrust turns those categories on or off based on what the user decides. Most marketing teams like it because the install feels relatively lightweight, with a snippet that lives on your site and integrates well with Google Tag Manager. Another perk is you can customize your cookie banner and overall user experience to match your brand (and your legal team’s requests), so you’re not stuck with a clunky pop-up that freaks visitors out. You’ll also find some advanced features like detailed audit reporting and tracking user preferences across sessions, but in my experience, those are more for the company lawyers than the marketers. Still, even if you only tap into the basics—like letting users opt in or out of different cookie categories—you can keep your site running with minimal fuss, and maintain a compliant marketing setup that doesn’t hamper your data collection any more than it has to.
