Your website should not be the only place where customers can review your products.

Make yourself available on platforms that you know people are using on a daily basis. Facebook reviews can give your business added exposure, because of its popularity.

This accomplishes two things. The other Facebook users will see the review. It may encourage prospective customers to click on your profile. Getting potential consumers to your page is half the battle. It required very little work on your part and almost no cost to accomplish this. Driving more people to your Facebook page can generate more traffic on your website as well. With that said, you still need to have a presence on those other platforms. Not all of those are relevant to every business.

However, a local restaurant would need a presence on this platform. Ask your customers to review your products. Amazon does this as well. Their platform is slightly different. Ask them directly in your retail location as well. This is a great strategy for small business owners and restaurants.

Customers who have had a negative experience are likely to go out of their way to speak their mind. So how do you get customers who had good experiences to share their opinions. You need to make it as easy as possible. Include a link on your website that brings customers directly to a review platform. Your customer would have to go to the TripAdvisor website in a separate browsing window.

Search for your business. Find a link to leave a review. Then write the review. Putting this link directly on your website saves the customer four steps. We want to encourage the customers who had a great experience to write reviews as well. Positive reviews generate lots of social proof. Again, this is simple and easy for your customers. The higher your open rate, the greater chance your customers will click a link within the message.

Now let me clarify this statement. You are not bribing customers to leave good reviews. Not a good review. In fact, if you look closely, the example even brings up the possibility of a negative review. With that in mind, offering an incentive will increase the customer experience. If your customers are happy, they will be more inclined to leave a positive review.
