What do I need to keep in mind?The quick and dirty answer: everything. But the longer answer is:
it depends on how much time and effort you're willing to put in. Here's a list, divided by effort and time:
Quick wins - Copy differences between shops
- Different pictures
- Differences in number of products
- Pricing tweaks
Medium effort - Different shops for different ads
- Ads that target more detailed demographics
- Different layout schemes
- Different channels (e.g. Facebook and e-mail campaigns)
Large effort - Sub-branding or off-branding
- Experimenting with different e-commerce platforms
- Testing different language versions
In each case, your action flow will be something like this:
- Hypothesis: I will sell more if I use black-and-white pictures
- Test: set up a second, identical Sayl Retail shop, but with b/w-pictures
- Check: send a link to half your customer base with shop 1, the other half gets shop 2
- Results: is there a difference in revenue from both versions?
