Judging the worth of an advertising channel based on $30 is like judging the worth of antibiotics based on a single use. I don't mean to be harsh, but your results don't really say anything about the merits of advertising on Reddit. Ads can impact purchases long in advance, but more importantly you can't expect single touch ads to work! Most users ignore an ad until they've seen it multiple times. I suggest you read more about effective frequency/advertising frequency. From personal experience, I can tell you that even good products with good ads usually start off as losers, then increase their return as they reach their full audience multiple times. Once you've achieved saturation in that channel, your ROI levels off and then begins to decline. Honestly - and I say this for the benefit of anyone who thinks this test is meaningful - that $30 would be better spent on a textbook about the basics of online advertising.
