Platform Overviews
Microsoft Clarity
Microsoft Clarity is a free behavioral analytics platform developed by Microsoft, widely used by marketers, UX researchers, and web developers to visualize user interactions through heatmaps, session recordings, and engagement metrics. Detection of Microsoft Clarity relies primarily on two script patterns, most notably the presence of the `clarity.ms` CDN domain and the characteristic inline initialization snippet that calls `window.clarity` or loads from `https://www.clarity.ms/tag/`, both of which are injected into the page `<head>` as part of standard implementation. These script-based signals are highly consistent across deployments because Microsoft controls the delivery infrastructure, meaning the CDN domain and function signature rarely vary between sites — giving detectors a reliable, low-false-positive fingerprint. AIWebsiteDetector's engine leverages these two script patterns to identify Clarity deployments across a wide range of site categories, from e-commerce and SaaS landing pages to editorial and lead-generation sites. Because Clarity is offered entirely free of charge by Microsoft with no self-hosted option, every deployment routes through Microsoft's own CDN, making it one of the more straightforward analytics tools to detect with high confidence — there is no on-premise variant or custom domain proxying that would obscure the canonical signals.
Facebook Pixel
Facebook Pixel is a JavaScript-based analytics and advertising tracking tool developed by Meta, used primarily by e-commerce brands, digital marketers, and businesses running paid campaigns on Facebook and Instagram to measure conversions, build retargeting audiences, and optimize ad delivery. The AIWebsiteDetector engine identifies Facebook Pixel implementations through a combination of 1 distinct script pattern and 2 HTML patterns, targeting the characteristic `fbevents.js` script load from Meta's CDN infrastructure along with inline initialization code and associated HTML markup signatures embedded in page source. These signals are reliable across a wide range of site types, from small business storefronts to large-scale retail platforms, reflecting how broadly the pixel is deployed regardless of the underlying CMS or technology stack. Facebook Pixel is provided free of charge as part of Meta's Business Tools suite, accessible to any advertiser with a Meta Business account, which contributes to its near-ubiquitous presence across the commercial web and makes it one of the more consistently detectable third-party scripts in widespread use.
