When potential buyers come to your site, most of them have the same questions and concerns:- How much does the delivery cost?
- Can the item be returned?
- How many days to return the goods?
- How fast do you deliver?
- Where are the goods made?
- and many other similar questions
And if there are any obvious advantages of buying from you, you must clearly communicate this to your users. It can be free shipping on all orders (that's a great advantage today) or even free shipping after a certain threshold (it's also better than nothing, moreover it's an incentive for customers to spend more to reach the threshold).
If you have a great refund and return policy (let's say 90 days and very simple return rules), then you certainly have to communicate. If your products are manufactured in the USA and you are selling for US customers, you have to scream about it, because it's super important nowadays.
I hope that you understand the logic of what must be conveyed to the user. For many of your visitors the Homepage may be the first page they land on and the faster you communicate that information for them, the faster they will understand these advantages and will be more motivated to shop from you.
Below you can find a few examples from different stores. Based on my experience such sections are especially important for the stores with expensive and quite complex products, where such things as shipping, returns, refund, country of manufacture are more important.
