Google De-lists on Key Search Terms

Search DuckDuckGo for “polygraph” and you’ll find, which hosts more documentation on polygraphs than any other site on the Internet, in the top 10 results. The same is true for searches on “polygraph” with Microsoft’s Bing search engine (in the United States), with Russia’s Yandex search engine, and with the open-source searX search engine.

Google Search Analytics shows that from 29 March 2018 to 26 June 2018, there were no clicks via Google searches on “polygraph” to any page on

There were only 7 clicks via Google searches on “lie detector” to any page on

Similarly, there were zero clicks via Google searches on “polygraphs” or “lie detectors.”
