We run a network of product microsites that use PricePlow's API to hook users up with good deals and free samples. The new microsites are actively maintained (blogging, product updates, support questions, security) and definitely not passive, but some of our older ones from 2010-2011, like http://www.coconutwaterlife.com http://www.coconutwaterlife.com sit around collecting Amazon money for doing next to nothing. The non-maintained network of sites earns about $500/month. That sounds great, but honestly, I wasted so much time building so many of them -- scaling business in the wrong direction instead of building a real brand -- that at this point, I believe that had I spent the time working on the main PricePlow setup in those two crucial years, my returns would be far higher than what I'm getting from screwing around with a ton of microsites. Plus, pareto principle. 10% of the old sites make 90% of the passive revenues. The rest of them were total WOMBATs.
