That depends on how big the differences you're looking for are. When you've got an early product, there are probably things you can do that 2x as many people will like as dislike. Even a small set of customers will be good for discovering this. When you've got a mature product, you should be optimizing around the edges and need a large sample size to find those 1% wins. Likewise if you don't have scale, there are a lot of well-known best practices that probably improve your site by 5-10%. You probably don't have sufficient volume to discover test those ideas, so following general best practices is a good idea. But if you have scale, you can and should A/B test the heck out of everything. And then do it again in a couple of years in case the answer changes. |
