List popular products and similar products
Amazon is the king of social proof. If you look at Amazon's website, you'll see many examples of social proof. "Hot Product", "Best Selling Product", "The same people who bought this product also bought...", "Frequently buy together" – link your products in a variety of different ways (this makes a difference for the SEO we mentioned earlier help) and sell more products right away.

Did you see the orange label "Bestseller"? This is useful for customers who are not searching for a specific item or are unsure of two items. In this case, the Latest Mailing Database customer may choose the best-selling product.

List supplementary items
You can help your customers by giving them an idea of what else they will buy after viewing this item.

Another way to sell more products at once is to offer complementary products and direct customers to items that are often purchased together.
Include customer reviews of your product
If your customers are not only sharing with the world that they love your product, but are actually showing it, it's the perfect way to prove that the product is great and that others trust your store.

Create a sense of urgency by sharing some real-time data
Show your customers that there are real people shopping on your online store at this particular moment. All of these real-time interactions influence people's decisions. By creating a little sense of urgency and the impression that the product is ideal and likely to sell out quickly, it gets customers to act quickly.
