Are recommendations important on e-commerce websites?

For my university final year project I have created an e-commerce website with some recommendations. Now I need to conduct a questionnaire to view how customers view these recommendations. Are they helpful or not? I will attach a link to my website. Please have a look at it and access the feedback section ( it is on the right of "Categories"). It will gonna take you 2 mins to complete it! Thank you !
