"Add to Cart" link vs product-page link: cart links extend your window

"Add to Cart" link vs product-page link: cart links extend your window
A SiteStripe "Add to Cart" link drops the item in the cart and gives you a 90-day window if it stays there — vs the standard 24-hour window on a normal product link.
n=1,500 clicks, same product:
— Standard link: 24h window, 3.1% order rate
— Add-to-Cart link: 90-day window, 3.8% order rate (+0.7pt from delayed buyers)
Tradeoff: cart links feel pushier and can lower click-through ~15% because shoppers expect a research page, not a cart.
So what: use Add-to-Cart links for high-consideration items people buy days later (mattresses, appliances). Use standard links for impulse buys closing inside 24h anyway.
