Need app recommendations for collection merchandising based on visitors - new vs returning.

[barrymelrose]

Hey everyone,

Looking for some recommendations or ideas for tailoring the product orders on collection pages to new & returning visitors.

For example, a new visitor browsing the Women's Tops collection might convert better with best selling products listed at the top, and conversely a return visitor might want to see new arrivals products up top. 

I see more focus on tailoring content on homepages or landing pages from the apps I am finding, but would like to focus just on the product ordering on collection pages first. 

Thanks for any and all feedback.
