The aim of this study was to quantify the impact of WBDD on digital information seeking and donor recruitment.<\/jats:p><\/jats:sec><jats:sec><jats:title>STUDY DESIGN AND METHODS<\/jats:title><jats:p>Google Trends data were used to quantify seeking behavior on \u201cblood donation\u201d and \u201cblood donor.\u201d Differences in relative search volume (RSV) between the 3 weeks surrounding WBDD and the rest of the year were calculated. Second, mean differences in RSV were compared to assess the additional effect of hosting using translated search terms. Third, we compared the period around WBDD with the control period regarding page views of the Sanquin website and Facebook likes and number of newly registered donors in 2016.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>The mean RSV for <jats:bold>\u201c<\/jats:bold>blood donation<jats:bold>\u201d<\/jats:bold> in the period of interest was 78.6, compared to 72.1 in the control period (difference, 6.5; 95% confidence interval [95% CI], 1.2\u201011.8). For \u201cblood donor\u201d this was 78.9 compared to 65.9 (difference, 12.9; 95% CI, 8.1\u201017.8). We found no additional effect of hosting. In the period of interest, the website of Sanquin was visited 6862 times a day and 4293 times in the control period (difference, 2569; 95% CI, 1687\u20103451).
