How to display review star ratings in google search results

Question

I am on ecommerce platform volusion (volusion.com) and it appears schema data is present in the code for reviews, however it does not display in google search results. Am I missing something. Here is a link to an example product and the schema that is coded on the page for reviews.

itemtype="http://schema.org/AggregateRating">
            <span class="v-reviews__item">
                <span class="v-reviews__avg-text">Average Rating:</span>
                <img class="vCSS_img_star_avg_rating v-reviews__star-img" src="/v/vspfiles/templates/keri/images/star5.gif" alt="" />
                <span class="v-reviews__avg-rating">
                    <span itemprop="ratingValue">5</span> of 5
                </span>
            </span>
            <span class="v-reviews__item">
                <span class="v-reviews__total-text">Total Reviews: <span itemprop="reviewCount">4</span></span>
            </span>

Answer 1

You might want to follow the guidelines and register your interest as mentioned in reviews.

To participate, implement the markup, follow the guidelines for either critic reviews or review snippets, and register your interest in the pilot.

Hope this helps!
