A bad example from Cupshe:
They don't have any CTA buttons even when I hover over product listings. They don't motivate shoppers to take further down the funnel.
A bad example from America Eagle:
They don't have any CTA buttons in the Mobile version of the category pages. Yeah, you can open a product page by clicking on the product image and title, but there is no clear call to action to motivate users to go through the funnel faster.
A mediocre example from Mavi:
They show a Quick View button when I hover over product listings and from the modal window I can add the product to the cart, but the problem is that they don't show any product details or product images there
A good example from PuraVida in Mobile view:
They show the Add To Cart button in each product listing for Mobile users (while for Desktop users, they show it after hovering over a product listing). In their case, it's a reasonable approach, because they are selling cheap bracelets and jewelry and shoppers can purchase it even from product categories.
A good example from PuraVida in Desktop view:
After you hover over a product car, you see all available product variants, arrows to see all the images and a very prominent Add to cart button which encourages users shoppers to go down the funnel.
A good example from Tinyritauls
They have a very prominent Add to cart button on each product card on category pages. They are selling very simple visual-driven products where ATC buttons are very relevant since users don't necessarily need to read detailed info about the product.
An interesting example from Gymshark
They have 2-product per line layout on collection pages, so they can't use standard CTA buttons. But since it's crucial to have some CTA elements, they added 2 icons for adding products to the cart (top left corner) and to the wishlist (top right corner).
Even though it's not so powerful as standard prominent CTA-buttons (like on Puravida or Tintyrituals), it's better than nothing.
