Dozens of education-related websites transmitted information on visitors through the Meta Pixel.
The Markup tested hundreds of education-related websites based on work from computer science researchers from the University of Chicago and New York University this year. The researchers used public databases of K-12 schools to develop a list of education-related websites that were frequently linked to from schools.
We ran an automated Blacklight scan on 114 of these sites. You can read more about how Blacklight conducts its scans here.
The results showed that of these sites, 31 employed the Meta tracking pixel. We included one additional website which we suspected to contain a tracking pixel, collegeboard.org, to bring the total to 32 websites.
We then manually inspected the network traffic while visiting these sites. We looked for any network calls to Facebook servers for the following events:
- A page view event when the page initially loaded, sending the name of the page, the URL, and a user ID.
- A button click event when a user clicked on a button to log in or access an internal link, sending the button text.
When we found evidence of any of these taking place, we documented it with a screenshot showing the network activity in the browser’s Developer Tools’ Network activity panel showing the call, and the information sent. We also included a HAR file for the testing session for each site. A HAR file is an archive format supported by most major browsers that contains a recording of all network requests made and received during a browsing session. (Note: Any instance of a login email or password appearing in plaintext in a HAR file was replaced with the string MARKUP_REDACTED).

meta-pixel-edtech-blacklight.csv 3KB. 33 rows. First row is the header.
-
We created folders for every website we tested. Inside each folder, there are:
- screenshots of relevant data being sent to Facebook via the Meta tracking pixel
- HAR files saved during the process of documenting the data collection
The data format of meta-pixel-edtech-blacklight.csv is as follows:
| Column | Description |
|---|---|
| organization | The organization of the websites we tested. |
| domain | The domain of the websites we tested. |
| bl_domain | The domain of the websites we tested, as it appears in Blacklight. |
| third_party_trackers, cookies | The number of ad trackers and third-party cookies found on each website. See the Blacklight repo for more details. |
| canvas_fingerprints, session_recorders, key_logging, meta_pixel_events | Tests for the existence of canvas fingerprinting, session recording, key logging, and Meta pixel events. See the Blacklight repo for more details. |
| ga | Test for the existence of Google Analytics’ “Remarketing Audiences” tool. See the Blacklight methodology for more details. |
