How Site Search Terms Leak to Ad Trackers Through the Page Address

A site’s own search box is where visitors type what they actually want. On a pharmacy it’s a medicine. On a lender it’s “bankruptcy”. On a clinic it’s a symptom. Nobody types those into a page title, but they type them into search.

Most sites put the search in the page address: /search?q=pregnancy+test. And nearly every tracker sends the page address with every event. Put the two together and the search goes to every ad network on the page.
