I need to do some split testing on my website. Test headlines, colors, words images, price etc. Do you have a good strategy for this? I have about 100 visitors/day. How long should one test last for me to be able to know what the test really gives? 1 week? 2 weeks? 1000 or 2000 visitors? This is the website that I'm going to test: mxtrainingjournal.com
