About OneTrust

OneTrust is a privacy-management company whose consent-management platform (CMP) is one of the most widely deployed cookie banners on the web.

Its script from cdn.cookielaw.org runs before anything else, reads or writes a consent-state cookie such as OptanonConsent, and blocks or releases other trackers on the page based on the choice recorded there. It's the banner itself, not something a banner would need to disclose.

Often loaded alongside

Sites that load OneTrust most often also load Google Analytics (68%), Google (46%), Google Ads (44%), Adobe (26%), and Amazon Advertising (14%).

Understanding this page

What the tracker categories mean
What "advertising," "analytics," "social," "consent" and the rest actually mean for a company or a cookie, and how CookieTosser decides which one applies.
First-party vs third-party cookies (and why "first-party" still tracks you)
What the distinction actually means technically, why browsers only block one of the two, and how CNAME cloaking, server-side tagging and cookies like _ga let sites keep tracking under their own domain.
How to block or limit trackers
Browser privacy settings, content blockers, Global Privacy Control and clearing cookies compared honestly — what each one actually stops, what it doesn't, and what it costs you in return.
