The Wikimedia Foundation's first two program evaluations of 2015 have been published on Meta. These examine the annual Wiki Loves Monuments (WLM) and other photo competitions that have been held around the globe, with an eye towards finding what worked and what did not. Although WLM is an international contest, it is organized separately in each country, with separate budgets and contests in each before the winners advance to the global finals. It was first held in the Netherlands in 2010, and the success there encouraged organizers in other countries to join.
The evaluations reveal that in the last three years (2012–14), WLM has possibly fallen victim to its own success and seen diminishing returns: the average total number of uploads has decreased from a high of 6,266 images in 2012 to 2,714 in 2014 even as the average money spent per upload has increased from US37c to 90c. While the total number of images increased from 2012 to 2013, it was less than half that in 2014. The number of images in use on Wikimedia programs has dropped both in total number and percentage, and the cost per used image has gone up from $3.03 in 2012 to $6.31—although this is an improvement on 2013's $6.61. Cost per participant was, on average, about $25. About 1% of the total image uploads were later rated as "quality" or "valued" images.
The users participating skewed heavily towards people who had never edited Wikimedia sites: over the three studied years, about 1,400 current and 14,000 new users participated. The conversion rate into continuing editors, as measured by having at least one edit three months after the competition, is 2.4%. Extending this to twelve months after the competition (for programs that ended before February 2014) shows that the programs netted 16 "active" new editors, or 0.3%—those who made more than five or more edits in the studied period.
The overall data analysis by the WMF suggests that "When planning a photo event, it may be useful to try to balance group size with both new and experienced users to increase use and ensure high quality uploads." For funding, the evaluators recommended that the WMF be "cautious about the investment level" amidst the contest's diminishing returns. E
