Optimizing a website is not an easy thing. You can read dozens of guides written by top experts in the industry, use their tips to create experiments with Optimizely, and see conversion rates slipping. Do you know this feeling? I do. Also, all the guides are useful only when you have thousands of visitors a day, otherwise, you might be unable to spot the difference. What to do to make the most of your Optimizely experiments even if you have moderate traffic? Add user feedback gathered with Survicate website surveys to quantitative analysis of your experiments.
