Reviews help your users and your SEO by keeping the site updated with unique content. Here’s how you can get more reviews on your site.
Feature a Review Section on Your Site
– Build a section on your website where you can house and display your user reviews, and if appropriate, include categories for your customers to rate your products on. Also, provide your users a chance to share photos of themselves with your products. This will make the reviews more useful to other users and will give your review section the power to become more social and at the same time visual which will provide potential users a better picture of how your products or services can work for them.
Get Customers to Leave Reviews
– Make creating and posting a review on your website extremely easy for your users. Don’t create any hurdles for them to overcome before they can actually leave a review. You can make it easy for your users to leave a review of your products or services by keeping them signed in or by even allowing them to leave a review without signing in.
Ask Your Users About their Experience
– Simply ask your users how they liked their experience. Position your pitch as a way for each of your individual customers to help other users by offering their own opinions on your products or services. Ask your customers to help you provide a better experience by sharing their opinion. This passive ‘ask’ is actually the key to success.
Keep Testing
– Keep in mind that not all users out there will respond to the same type of messaging or design. So it is vital that you get to know what your customers will respond to by running a test on your messaging. Try to create different versions of your pitch and send them to different customers for you to see which version yields the most number of reviews.
