In 2019 I will start a new Dutch podcast series about CRO (Conversion Rate Optimization). I want to get a better insight into the Dutch CRO field, get an idea of how everyone is working, what the struggles are and use this platform to exchange knowledge and experience. I'll be interviewing people working in/with CRO at agencies, tool vendors, merchants and other end-users.
If you can understand Dutch I'd love for you to get subscribed to the podcast through your favourite podcast tool (like iTunes, Spotify, Google Podcasts, Soundcloud, Stitcher, Pocket cast) and you can also request to join the private Facebook group we use for discussions outside of the podcast itself.
Recently I've seen some (often absolute) statements going around, generally in the line of "open source commerce platforms are a terrible idea". Now of course different solutions always have different pros and cons.
A hierarchy of evidence (or levels of evidence) is a heuristic used to rank the relative strength of results obtained from scientific research. I've created a version of this chart/pyramid applied to CRO which you can see below. It contains the options we have as optimizers and tools and methods we often use to gather data.
