Tracking Pixel

A tracking pixel is a 1x1 transparent image or, more commonly today, a JavaScript snippet embedded on a website that tracks user behavior and sends data to a third-party platform. Tracking pixels are the foundation of digital advertising measurement — they record when users visit pages, click buttons, add items to carts, and complete purchases, then report this data back to advertising platforms for attribution, optimization, and audience building. The most common tracking pixels include Meta Pixel (formerly Facebook Pixel), TikTok Pixel, LinkedIn Insight Tag, Snap Pixel, Google Ads conversion tag, and Bing UET tag. From a privacy perspective, tracking pixels collect personal data and share it with third parties without the user's direct awareness. Under GDPR and Saudi PDPL, loading tracking pixels before obtaining explicit user consent is a violation. The pixel fires on page load, meaning data is collected before the user has any opportunity to consent. Arqam360's script quarantine system intercepts and blocks tracking pixels from Meta, TikTok, Snap, LinkedIn, Google, Bing, Segment, Mixpanel, Hotjar, and Clarity until the user grants consent for the relevant category.
