Should You Block This Without Consent?

Yes. Engine USA is a programmatic ad marketplace that relies on third-party cookies and cross-site user tracking for ad targeting. It has no functional purpose for site visitors and requires consent under GDPR and ePrivacy regulations.

Is Engine USA GDPR compliant?

Engine USA typically loads marketing trackers, which are not strictly necessary for your site to work. Under the GDPR and the ePrivacy Directive, non-essential cookies and trackers must stay blocked until a visitor gives clear opt-in consent. So Engine USA can be fully GDPR compliant, but only if your site holds its scripts until consent is granted and lets visitors decline just as easily. Compliance depends on how your site loads Engine USA, not on Engine USA itself.
