Mass media articles about effective charity and the availability of GiveWell recommendations.
Seeding and supporting local groups, like GWWC has been focusing on.
Niche fundraising, like REG did for poker players.
Why the heavy downvoting? There have been relevant recent discussions of this, and they include http://effective-altruism.com/ea/qj/meta_up_and_down_voting_should_be_added_next_to/ and http://effective-altruism.com/ea/q7/my_coming_of_age_as_an_ea_12_problems_with/5o8?context=1#comments

It does seem clearly to be worth this expense. I'm concerned that .impact/the community team behind the survey are too reluctant to spend money and undervalue the time relative to it. I suppose that's the cost of not being a funded o...
more research of that type is definitely needed, we're currently focusing our efforts in that direction on encouraging other people to do it.
Roughly how many resources (person days) have you put into this, and how many do you plan to?
Does ACE place to run any more original studies life the leafletting-effectiveness study collaboration? Would that be what researchers potentially do?
Have you thought about running future matching fundraisers through an organisation that focuses on fundraising, which in the EA global poverty world I guess'd be Charity Science? I imagine they'd be able to put extra time into promoting it, and'd have a comparative advantage in doing this, whereas you'd have a comparative advantage in earning to give.
