Ghostery focuses on giving consumers transparency, education, and control over the data they provide to the sites they visit. The underlying technology for how the scripts are blocked is similar for Ghostery and its competitors. The core difference is that services like Adblock Plus and its competitors are blunt instruments. They are mainly "all-on/all-off" switches. They give the consumer very little transparency into what is actually happening.
Ghostery approaches it differently: we don’t block anything by default. The consumer chooses what tracking technology to block. Our business model is transparent – consumers can opt-in to share anonymous data with us. We package this data into a software platform that businesses use to drive revenue from making their website experience cleaner, faster, and safer.
