On the 13th of January 2009 300 members of the Research Plus monitor group completed a private internet-based questionnaire. 53.3% of the sample were male, 15.7% in their twenties, 37.0% in their thirties, 32.3% in their forties, 11.7% in their fifties, and 3.3% in their sixties.
It’s interesting to see that only a third of the Wikipedia users saw the request for donations as it was a very large banner, indicating a degree of ad blindness even higher than for contextual advertising.
Q1: Do you know the online free encyclopedia Wikipedia? (Sample size=300)
Yes (to SQ1) 77.7% No 22.3%
Q1SQ1: Have you ever used Wikipedia? (Sample size=233)
Yes (to SQ2) 95.7% No 4.3%
Putting the two together we get:
Q1+Q1SQ1: Have you ever used the online free encyclopedia Wikipedia? (Sample size=300)
Yes 74.3% No 3.3% Don’t know the site 22.3%
Q1SQ2: Did you notice during the second half of last year a banner message on Wikipedia asking for donations? (Sample size=223)
Yes 33.6% No 66.4%
Of those 75 that noticed the solicitation, one person actually donated.
