We have receive glowing reviews of our products via email. It's great to receive them, but we already know our products are top notch. How do we get our customers to post their reviews in relevant discussion forums?
First, congrats on being awesome and getting great feedback!
When I receive great reviews by email - I profusely thank them for the feedback, let them know how much it means to me, and then I often ask the client if they'd be willing to post that publicly and offer a few site links as suggestions. Generally they are more than happy to do that. This may sound simplistic - and it is - but it has also proven quite effective.
I'd be happy to provide some examples - just send me a message.
Make it effortless for your customers to do so. Survey them via email and once they have given you a positive review (use NPS to make it simple through radio buttons) push them to a landing page where they can share their message on the discussion forums you wish to profile their review.
Great question, I was in a similar place in 2014. Since then we've increased focus all efforts to one medium, G2 Crowd. In 2015 we added over 85+ reviews and was voted Top SaaS Customer Experience this Spring! We had amazing company: Google, Slack & Hubspot, were also ranked.
It's an ask at the right time, if the feedback is so great most clients are happy to help. I'd love to share more, email or call!
