Facebook Ads: A Social Change Experiment

We’re experimenting with Facebook Ads and sharing what we’ve learned.

By Gideon Rosenblatt, Executive Director

Note: In November 2009, we changed our name from ONE/Northwest to Groundwire. This article was originally published in September 2009, when we were still ONE/Northwest. We did some experimenting with Facebook ads as a way to gain fans for our ONE/Northwest’s Fan Page. This is what we learned.


Like most organizations starting a Fan Page on Facebook, we focused our initial efforts on friends and family members. The results were great. Within a few weeks of asking staff to send invitations out to friends we had more than 400 fans – and lots of nice feedback in the form of postings and other feedback on our page. It was very little work and the results were tangible.

After three weeks, the results of our staff invitations trailed off and our sign-up curve started to flatten. There are many creative online organizing tactics we could have used to extend the curve, but we decided to first try some experiments with Facebook ads.

Over a ten-day experiment, we spent $292.55 and added 120 new fans. That’s an average of $2.44 per new fan who signed up to our page. We used a budgeting feature that enabled us to cap our experiment to $30 per day.

We chose to use the “pay per click” mode of advertising rather than the “impressions” mode. That means that we paid every time someone clicked on our ad rather than paying for people to simply see our ad. Both are good strategies. It just depends whether you’re trying to build awareness or build a base. In our case, our cost per click averaged 52 cents over our total 563 clicks to our page. Remember, though, that just because someone clicks through to your page, doesn’t make them a fan. Only 120 of the 563 visits to our page resulted in a new fan – that’s roughly one in five.

We ran a variety of ads in our experiment in order to test what writing and what images worked best, and – most importantly – what kinds of people were most likely to join us. We ran ads in different places too. Not surprisingly, we did really well in our hometown of Seattle and in Portland, Oregon where we have an office. We didn’t do that well in San Francisco; quite possibly because our name “ONE/Northwest” might not seem relevant to potential fans there.

One thing we learned in our experiment is that targeting is an important tool for lowering the average cost per fan. Our ad in San Francisco resulted in us paying $9.30 for each of the two fans who joined us there. Ouch. Contrast that with an ad we ran in Seattle that targeted hikers with some good ad copy and was backed up by an interesting story on our page about a great project we did for Washington Trails Association. Those ads resulted in new fans joining our page for an average cost of $1.95 per fan. Similarly well-targeted ads talking about sustainable farming and food led to fans joining our page at an average $2.06 per new fan.

In sharing this information, we’re conscious of the fact that we run the risk of turning off some of our new fans by appearing to be too mercenary in what we’re doing. Nothing could be further from the truth. We ran these ads to learn how this new medium works so that we can share this knowledge with the great social change organizations we serve. We also ran the ads to introduce our work to a whole new set of people who don’t already know us – and that seems to have worked.

One important outcome from our ads is a diversification of our fan base on Facebook. After relying on our own personal networks for outreach, 65% of our fan base was male. Now, after just ten days of advertising, this gender gap has closed dramatically. We started seeing some younger fans join us, too, broadening the age-range of our supporters which is exciting.

Facebook advertising analytic reports don’t make other demographic data available but we’re noticing a lot more diversity when we look across the many new faces now joining us – and that may be one of the most rewarding and exciting outcomes of this little experiment. Facebook ads appear to be helping us break out beyond our own social circles and extend our appeal to whole new groups of people we haven’t reached before.
