Increasing online sales can be a challenging task for all kinds of businesses and companies. Whether you sell books or any digital products online, you want your customers to fill their virtual carts with as many products as possible. However, you cannot force online shoppers to buy products, but you definitely can lead them in that direction.

In an attempt to boost sales, many small companies or store owners turn to seminars, books, or web pages that help them more sales by sharing marketing strategies and tricks.

Unfortunately, many of them throw around many complicated strategies that are difficult to understand and hard to memorize. On the other hand, there are many easy-to-understand selling techniques you can practice. So which ones are most beneficial for your business and easy to practice? 

Cross-selling and up-selling are two immensely popular selling techniques that have helped many eCommerce businesses to increase online sales fast. These are good ways to retain existing customers and acquire new ones.

What is Cross-Selling?

Cross-selling is a selling strategy in which an additional product is recommended to the customer while he or she is buying the primary product. The additional product is the complimentary one or an add-on of the primary product. The main purpose of cross-selling is to improve the overall buying experience of a customer.

Cross-selling is more focused on increasing sales volume. However, it is necessary to pair up the right products; otherwise, it will not work.

Examples of Cross-Selling

  • You are shopping in an electronic store for a new smartphone. The salesperson recommends a screen protector or a phone case to go along with your phone.
  • You are trying a new pair of shoes, and the salesperson presents a pair of socks that matches perfectly with your shoes.
  • You are ordering your favorite burger from your favorite fast-food chain, and the salesperson asks if you would like to add fries, drink, or shake to your order.

Pros and Cons of Cross-Selling


  • It helps to boost the sales online of low-margin products.
  • It helps to increase customer satisfaction and loyalty.
  • It facilitates customers through lower bundled prices, more variety in terms of products, and one-stop shopping.
  • It helps a lot in business growth and success.


  • It can be distracting for the customers.
  • If it is poorly timed and not properly planned, it can result in losing potential customers.

What is Up Selling?

Upselling is another selling strategy focused on convincing customers to purchase a more expensive product than the one they initially wanted to purchase. The more expensive product can be an updated or a premium version of that same product or product similar in features and functionalities but a higher-priced alternative. Therefore, it is more focused on increasing the sales value.

Examples of Up-Selling

  • You are ordering a pizza at your favorite restaurant, and the salesperson asks if you would like to buy one in a larger size.
  • You have picked out sunglasses, and the sales representative offers you to add UV protection for an additional cost.
  • You are car shopping and looking for a basic model, but the salesperson points out the leather seating, DVD player, Bluetooth, and security features in luxury cars.

Pros and Cons of Up-Selling


  • It helps in building customer satisfaction and loyalty.
  • It increases customer lifetime value.
  • It helps in improving the sales value.
  • It helps to add value to the customer


  • It may appear a little too pushy to the customers.
  • If mishandled, it can appear quite a salesy in the eyes of a customer.

Top powerful tips on how to massively boost online sales with cross-selling and up-selling

Upselling and cross-selling provide more online sales and can help you a lot in your business growth and success. Some of the tips on how to boost sales with these two techniques are:

Determine which products give the best results

It is never a good option to bombard your customers with tons of product suggestions and recommendations. So it is always better to stick to limited products that give the best results.  In order to boost your sales, use limited products that give excellent results. In the end, you don’t want to disappoint your customers.

Always demonstrate the value before initiating the pitch

Once you have determined that a particular cross-sell or up-sell offer is suitable for your customer, your work probably is not done. You need to ensure that a customer is fully aware of the value of an additional product in his or her life.

Reward customers for their loyalty

Once you have convinced a customer to spend more money by buying a premium version of a product or additional product and remain loyal, you must take the initiative and reward them for showing loyalty. You can offer them a discount code or a free coupon (loyalty programs).
