An understanding of XML feed files will be important for those using the Merchandiser module. This shouldn't be a hindrance to most organizations with the technical aptitude to implement Monetate to begin with, but if outsourcing that task, ensuring that an automated update of the product feed file is included in the scope of the implementation is important. We found that the Monetate staff was extremely helpful in assisting with the validation of the data in the product feed file and in ensuring that feeds for different properties were being properly updated.
While Optimizely has a number of useful features, Monetate had a much broader portfolio and greater ease of use. We also found that the Monetate team was very responsive and easy to work with on projects.
