The below link will take you to the data we collected in our experiments. The data is described in more detail in Section 5 of our paper. We provide this data as a resource to the scientific community, if you use it, please cite us as [BibTeX].
The names of the folders represent the specific feature (e.g. gender) that was tested in that experiment. Inside the folder you can find the data for each day the test was run and each value of the given feature (e.g. male, female, other, control). The HTML files contain the first page of Google Search results returned for search terms according to the filenames.

The keywords chosen for these test from Google Zeitgeist and WebMD and they are also described in more detail in the paper.
