Trackers and pixels feeding data broker data stores

Beyond buying and selling data, the data broker infrastructure also accrues data via feeds from third-party trackers, tags and pixels. A new report from privacy and security company, Lokker, looked at web privacy across more than 3,400 sites and shows broad use of these identifiers with 47% of websites using Meta Pixel, including 55% of S&P 500, 58% of retail, 42% of financial, and 33% of healthcare.
