Instantly reveal the trackers on any website using this free website privacy inspector.
Blacklight lets you scan any website to see how your data is being collected by entering the address of a website. It scans the site and reveals what tracking technologies are being used.
Personal data collection is a big business. Most websites use some sort of tracking technology, whether it’s cookies or something more extensive, such as ad trackers, key logging, session recording, canvas fingerprinting, or tracking by Facebook and Google.
These are the types of tracking that Blacklight identifies and displays after you use their privacy inspection tool. What do these trackers actually do? What data do they track and collect? Read on to see how you’re being tracked. If you’re not familiar with key logging and session recording, you may want to have a look.
Third-party cookies are a small piece of data that tracking companies store in your web browser when you visit a website. This bit of text—usually a unique number or string of characters—identifies you when you visit other websites that contain tracking code from the same company. Firefox, Microsoft Edge, Brave, and Safari all block third-party tracking cookies by default, and Chrome has announced that it will phase them out.
Key logging is when a first or third party monitors the text that you type into a webpage before you hit the submit button. This technique has been used for a variety of purposes, including identifying anonymous web users by matching them to postal addresses and real names.
Session recording is technology that allows a third party to monitor and record all of a user’s behavior on a webpage - including mouse movements, clicks, scrolling down the page, and anything you type into a form even if you don’t click submit.
Canvas fingerprinting is a type of fingerprinting that identifies users by drawing shapes and text on a user’s webpage and noting the minor differences in the way they are rendered.
The Facebook pixel is a piece of code Facebook created that allows other websites to target their visitors later with ads on Facebook. Common actions that can be tracked by pixel include viewing a page or specific content, adding payment information, or making a purchase.
Google Analytics “Remarketing Audiences”
While most of the functionality of this service is to provide developers and website owners with information on how their audience is engaging with their website, the tool also allows the website to make custom audience lists based on user behavior and then target ads to those visitors across the internet using Google Ads and Display & Video 360.
