Your customer can be your best sales person. You need to make it easy for them to recommend you. One way to initiate this recommendation is for you to ask them for a review. There are multiple platforms where reviews can be made.
Google My Business
Reviews added to your Google My Busines profile, which also puts you on the Google map, are included in Google’s assessment of your business and its relevancy in searches. Have informative reviews will boost your ranking.
Yelp
If your customers are often on Yelp, it is important to have current reviews. Yelp discourages asking for reviews, so don’t send a bulk request to your customers. Do a trickle of requests.
For solopreneurs and consultants, having recommendations on LinkedIn can help with your credibility on the platform.
Written Reviews
Often customers will provide you with a review in an email. These can’t be added to review platforms by you, but they can be added to your website in a “Testimonials” section.
