Here are all my top tips to boost conversion rate
Move product up above the fold - remember always mobile first
Stickie filters so you can tick the off with 1 click and not have to click on filters first
Infinite scroll . Many have 10-20 products per page
Showing more images per product so making it possible to swipe to the right to see more photos.
Reviews displayed on products
Finding out what filters people engage with and making it dominant and maybe shown at the top
USPs above the fold or loading as a banner between products.
2 grid system for products instead of 1. Testing both is worth it. Bigger or smaller images basically
Adding similar categories designed like instagram story thumbnails. At the top score the fold so you can easily navigate to other categories.
Stickie menu - great for if shop has many categories so people can click menu when they are far down the page
Sorting by best sellers in a short timeframe like 7-14-30 days - can use an app for this. They allows you to show what’s trending at the top. Usually brands have sorting by features or sorting by bestseller but it’s using lifetime sales data so it’s not relevant for today
Adding bestseller icons for key products and best for specific scenarios. Like best for traveling, best for exercising, best for calf pain (using compression socks as the example) (edited)
