Welcome to the Q&A Forum

Hi Schlomi. I'm Joey, one of the developers of WP Customer Reviews. I apologize for not seeing this earlier, but I'm glad I stumbled on it and very happy to help. Your question is one we get a lot. Carson sums it up best when he says you are at Google's mercy - they decide, and it's not just about the formatting of your snippets. You can see just how "hit and miss" it is by looking at the serps when you search on "powered by wp customer reviews" https://www.google.com/search?sourceid=chrome-psyapi2&ion=1&espv=2&ie=UTF-8&q=%22powered%20by%20wp%20customer%20reviews%22&oq=%22po&aqs=chrome.0.69i59j69i57j0l4.1099j0j4 As you can see, 20-25% of the listings have star ratings in the results. I'd love to see more, but it shows what's out there. The best thing you can do to improve your chances of ratings showing up in search is to upgrade - I see you are using version 2.8, which is several versions behind. We overhauled the plugin in September, which included improvements to the rich snippets. As an internet marketer, the intent of WP Customer Reviews was to get user generated content onto sites and have the ratings show up in SERPS. It does the job, but like always, Google decides what shows up. Thanks for using the plugin. If you have some ideas for improvements, drop me a line.
