You can create a link that you use throughout your website to encourage customers to leave a review. There are several sites that can actually give you a Google review link. Just search for a Google review link generator.
Then, once on the Google review generator website, search for your business and copy the link the website gives you. Now that you have your Google review link, you can start getting more Google reviews. You want to paste your customer review link anywhere on your website that makes sense. A good example of this would be to paste your Google review link after your customers purchase one of your products.
Additionally, you want to make your customer review link accessible on the homepage of your website, so that it is as easy as possible for customers to leave a review. You can even leave your business review link in your emails signature so that when you are sending out emails to customers or prospects they can see the review link even without visiting your website.
