'Add to Cart' CTAs extend your window from 24h to 89 days
A direct 'Add to Cart' link (not 'Buy Now') triggers Amazon's 90-day cart attribution. Few affiliates use the explicit cart-add URL. The playbook:
— Build the link: add /gp/aws/cart/add.html?ASIN.1=XXXX&Quantity.1=1 with your tag
— Use it for high-consideration items where buyers delay (appliances, fitness gear)
— Pair with copy: 'cart it now, it'll be there when payday hits'
— Standard product links still credit the 24h cookie — use both
— Watch the 'Add-to-Cart' report column to confirm it's firing
Carted-item order conversion ran ~18% in our sample (n=1,900) vs ~4% on direct clicks.
So what: for any niche with a delayed purchase decision, the cart-add link is your highest-leverage 5-minute change.
