The top 10 most popular education technology sites, as ranked by Teach 100, place on average of 10 trackers, that is, snippets of code that monitor what you do on a website and, oftentimes, share that with others. This is skewed admittedly by Alan Singer’s blog on the Huffington Post that places 49. The top 10 include the Department of Education’s Homeroom blog, which sends tracking information to YouTube, Google Analytics, Crazy Egg, and Foresee. “Visualized where your visitors click,” boasts Crazy Egg. (This sort of tracking data is not protected by FERPA, for what it’s worth.)
They’re not in the top 10, but Free Technology for Teachers places 15 trackers, according to Ghostery; Privacy Badger finds 21 on the site. Diane Ravitch’s blog places 4 according to Ghostery; Privacy Badger finds 3.
