Understanding website visitor identification has become increasingly important amidst privacy laws and consumer preferences for anonymity online. Distinctions are made between unique visitors, who are counted once within a given timeframe, and anonymous visitors, who deliberately hide their identity using methods like incognito mode or VPNs. Despite these efforts, anonymous users can still be identified through advanced browser fingerprinting, which collects multiple signals for precise identification. Google Analytics uses browser cookies to track unique visitors, but it is limited by potential inaccuracies when users clear cookies, use incognito mode, or switch devices. Identifying unique and anonymous visitors offers benefits such as improved fraud detection, marketing attribution, and enhanced user experience. Fingerprint, a visitor identification tool, uses browser fingerprinting and device identification to achieve high accuracy in identifying visitors, supporting various applications like fraud prevention and user personalization.
