Blacklight works by visiting each website with a headless browser running custom software built by The Markup. To learn more, read our methodology.
Websites containing advertising tracking technology load JavaScript code or small invisible images that are used to either build your advertising profile or to identify you for ad targeting on this site. These techniques are often used in addition to cookies to profile you.,Blacklight detected trackers on this page sending data to companies involved in online advertising. Blacklight detected scripts belonging to Centro, Inc., DeepIntent Inc, and forty-nine other companies.
These are commonly used by advertising tracking companies to profile you based on your internet usage.,Blacklight detected 118 third-party cookies on this site. Blacklight detected cookies set for Purch Group, Inc., Captify Technologies Ltd. and and forty-eight others
The Facebook pixel is a snippet of code that sends data back to Facebook about people who visit this site and allows the site operator to later target them with ads on Facebook. A Facebook spokesperson told The Markup that the company set up this system so that a user doesn’t have to be “simultaneously logged into Facebook and viewing a third-party website for our business tools to function.” Common actions that can be tracked via pixel include viewing a page or specific content, adding payment information, or making a purchase. The Facebook pixel appeared in thirty percent of popular websites when we scanned them in September 2020.
The TikTok pixel is a snippet of code that sends data back to TikTok about people who visit this site and allows the site operator to later target them with ads on TikTok. A user doesn’t have to be “simultaneously logged into TikTok and viewing a third-party website for our business tools to function.” Common actions that can be tracked via pixel include viewing a page or specific content, adding payment information, or making a purchase.,This website seems to be using TikTok pixel "advanced matching" feature, which allows the site to share data about visitors with TikTok even if users block TikTok cookies.
This site uses Google Analytics and seems to use its ”remarketing audiences” feature that enables user tracking for targeted advertising across the internet. This feature allows a website to build custom audiences based on how a user interacts with this particular site and then follow those users across the internet and target them with advertising on other sites using Google Ads and Display & Video 360. A Google spokesperson told The Markup that site operators are supposed to inform visitors when data collected with this feature is used to connect this browsing data with someone’s real-world identity. You know when those shoes you were looking at follow you around the internet? This is one of the trackers leading to that. This feature appeared in fifty percent of popular websites when we scanned them in September 2020.
