I provide conversion optimisation services on a price per day on a rolling monthly basis. I did it this way, because my background is in software development consultancy and everything was estimated and billed out on a daily basis. I also provide one off services which is normally priced based on how long it would take to complete. I prefer to work with customers on a rolling monthly basis because I can have an impact on many aspects of their digital marketing and business processes. It means I'm also not tied to only creating split tests but have the freedom to advise and have a positive impact on multiple areas of a business.
