As in prior years, search traffic (organic and AdWords) provided the majority of traffic to GiveWell's website.

True: GiveWell's 2012 traffic data show that search (organic plus AdWords combined) was more than 50% of website traffic, and prior years' data show search was also the majority. Mostly true: search was the majority in 2012, but the 'prior years' part holds for most but not all earlier years reported. Mixed: search was the majority in 2012 but not in prior years, or the reverse. Mostly false: search was a plurality but not a majority in 2012. False: search was well under half of 2012 traffic.

   “Web traffic”

None of the evidence gives a 2012 breakdown of traffic sources. E3, the 2013 metrics report, cuts off before its source breakdown, so the central part of the claim cannot be checked. On prior years, E1 shows search plus AdWords at about 55% of 2011 traffic, a majority. E2 shows about 47% in 2010, under half, so the 'as in prior years' part holds only partly. All sources come from GiveWell itself, and without 2012 figures the criteria cannot be applied.
