When someone is browsing your store there are two important important conversion actions you want them to take.
- Add a product to the cart
- Sign up for your email list or other method to keep in touch with you
Everything else on your store should be designed to improve the chances of someone doing one or both of those.
That's why having multiple add to cart buttons is such an easy and powerful optimization you can make to your Shopify store.
By adding a second button, you're adding another 1,000 pixels for your customer to take one of the key conversion activities.
Which makes sense right.
You're probably using 10x-100x that much visual space for product images and social images. While they are useful, they aren't going to give you the main action you want a customer to take.
There is one time where having only one add to cart makes sense. That's when you have a very small product page so the add to cart button is visible at all times.
But I could argue that if you can see your entire page at once, on the mobile or desktop, then you don't have enough information for customers to use to make a buying decision.
So what should you do?
If you only have one add to cart button on your product pages, add a second one.
If you have two, check that one is always nearby and can reached without scrolling too far.
Or you can install Sticky and get a second add to cart button added in two minutes. Not only that, but it will also make sure that the button stays visible no matter how far someone scrolls.
