So this text is part of what contains the schema data that Google data crawlers will be looking for, so you don’t want to explicitly hide it. However, there are a few workarounds. For instance if you wrap the snippet shortcode in a container with a targetable class, then apply some css to reduce the font-size of everything, except the stars, to nothing, you can get the effect of removing the text without actually doing so.
For instance:
<div class="aggregate-rating">
[RICH_REVIEWS_SNIPPET category="page" id="60]
</div>
<style>
.aggregate-rating {
font-size: 0px;
text-align: center;
}
.aggregate-rating .stars {
font-size: 22px;
}
</style>
That should do what you are looking for. Note: the font-size of 22px for the stars is arbitrary, you can style the stars however you like, as well as the container and whatnot (ie: the text-align: center;). the key is simply applying font-size: 0; to the container then targeting the .stars element within to override the font reduction.
Let me know if you need any further help.
