How do I verify my website is configured correctly?

Use the Google Structured Data Testing Tool to verify that your markup is well-formed and can be processed by Google.

How can I preview what my site will look like in Google?

It usually takes a few weeks before Google will show the star ratings in their search results. If you’d like to confirm everything is working correctly, you can Fetch your Website as Google. This is a tool that allows you to test how Google views your website which should show you the star ratings in action.

Before you can use the tool, you must have your website verified and setup in Google Webmaster Tools. Here’s a good tutorial on how to use the tool.

How long does it take for rich snippets to be visible?

Once you’ve installed the plugin, Google will discover it the next time they crawl your site (although it may take some time for rich snippets to appear in search results, if they do choose to display rich snippets for your site).

The star ratings don’t show up in Google

It takes time for Google to re-crawl your site and for rich snippets to appear in their search results. If it’s already been a few weeks and you tested your site’s markup and ran the Fetch as Google tool per above and they still don’t show up, read their FAQ.

Are there any filters or hooks?

Yes. There are several filters built into the plugin. These allows developers to modify the StarStruck content before it’s returned to the browser.

starstruck_content – executes before StarStruck is displayed on the post/page.
starstruck_comment – executes before StarStruck is displayed on each comment.
starstruck_mini – executes before StarStruck is displayed as read-only values.
starstruck_sidebar – executes before StarStruck is displayed in the sidebar.
startruck_template – executes before a StarStruck template (top ratings or content) is displayed.

The best way to figure out how filters work is by looking at the source code. You’ll be able to see the exact parameters and how the function works.

For example:

function your_filter( $content, $data ) {

    if ( $data = maybe_unserialize( $data ) ) {
        // do something with the data if you wish

    // more importantly, do something with the content
    // look at starstruck-content.php for an example

    // always make sure to return the content!
    return $content;
add_filter( 'starstruck_content', 'your_filter', 10, 2 );

For more information on how filters work, see the WordPress Codex.

Have a suggestion for a new filter or action? Let us know in the comments below or our support forum.

Installation Guide

It’s easy to install the plugin. Just follow the steps below. What’s most important is to verify that your theme has microdata setup correctly. Once you’ve done that, see the FAQ tab for more guidelines.

  • Download the plugin from your customer dashboard
  • Login to your WordPress site and visit “Plugins” => “Add New” in the sidebar
  • Click on “Upload” and then “Choose File”. Browse to the
  • Click on the “Install Now” button
  • On the plugins page, scroll down and find “StarStruck. Click on the “Activate” link.
  • You’ll then be redirected to the options page
  • Visit your site and view a blog post. At the bottom, you should see the star ratings

Setting up the Microdata

If you site has already been configured with microdata, StarStruck will automatically work once you accumulate ratings.

Google provides a free testing tool to see if everything is configured properly. If so, you’ll see the star ratings in the results.

If not, chances are you need to add microdata tags to your WordPress theme. The exact tags depend on the content StarStruck is displayed on. For this example, we’ll use the BlogPosting item type.

If you’re familiar with editing theme code this will be easy to do. You’ll need to modify your theme’s single.php (or possibly content.php or loop.php) file. There might even be a plugin that does this for you without having to edit the theme files.

The key pieces we need to add are:

  • itemscope itemtype=””
  • itemprop=”name”
<div itemscope itemtype="">

    <h2 itemprop="name"><?php the_title(); ?></h2>

    <?php the_content(); ?>


For different microdata item types such as products, restaurants, etc, see the Schema AggregateRating page.

Display the Ratings and Total Votes in the Sidebar

We have this setup on our Marketplace (see the right sidebar) and you can do it too. Just add the following code to your theme’s sidebar.php file.

if ( function_exists( 'starstruck_sidebar_ratings' ) ) {
  echo starstruck_sidebar_ratings();

Note: You might need to add some custom styles to match your theme.

    Hello everyone, our development team is working on an update to StarStruck. It should be ready in November.

  • weiching

    It can be used in ClassiPress Ads?

  • bsti

    I’m using classipress and I want only registered users to be able to rate authors. Can this be done with this plugin?

    • Bruno Carreço

      You have the option to disable anonymous voting globally. Meaning that only registered users will be able to rate posts, authors, etc..

  • brianjester


    I am looking at the widget to the right side of this page:

    (the comments page) and there is a rating widget there, is that part of the feature in the star starstruck plugin? If not, what plugin is that?

    Thank you

    @176042, I presume you mean, if ‘Starstruck’ can review services?

    • 176042

      Yes, that is what I meant to ask. I want current and former customers to be able to review the the services in Taskker by using Star Struck. Is that possible?

  • Bruno Carreço

    Taskerr itself provides the ability for service buyers to review services after they are completed.

    With StarStruck you gain the ability to allow users to rate the service at anytime. Works a little like a ‘Like’ button but in this case users are giving their rating to the services.

    I am looking for a way to have a rating for everyone on my classipress add listing site. Like ebay does. People are able to go on and rate their experience with a seller that listed and ad and they bought the item. Will this plugin do this and how would it work if you could do it.

    • Bruno Carreço

      @gatorman2014, you can use StarStruck to provide reviews for listings but these will be available at any time and to everyone.

      With StarStruck you gain the ability to allow users to rate listings at anytime similar to a ‘Like’ button but in this case users are giving their rating to the listings.

    Will this plugin out of the box get me the desired ‘stars’ next to my Google organic results? Are there special configurations I need to do in order to get the ‘star’ ratings in the Google SERPS for web design related searches in my local area?

    Anonymous likes this.
  • David S

    Also, does a user have to login in order to leave a vote? Is there a quick easy way to add votes to a page/post yourself?

    • Bruno Carreço

      Yes. Anonymous users can vote. You also have the option to disable anonymous voting.

      To add votes to a post, page or any other post type, you just check the related option under ‘Show star ratings on: posts, pages, etc…’

  • grafro


    I noticed by that the .png files are not in my CDN. Why can’t the star png files be stored into my CDN to improve site speed?
    Or how is it possible to do this? I asked already in forums but nobody answers there.

  • Bruno Carreço

    @grafro, to use a CDN for your images you would need to change the ‘StarStruckPath’ variable inside the ‘starstruck-init.php’ file. This is not recommended if you’re not comfortable with editing PHP files and understanding Javascript.

    Nevertheless, we’ve registered your suggestion about using a CDN for images. It’s something we will consider in a future update.

      Thank you for your excellent help!

      I managed to change the path to my CDN path and it works fine!

      Keep on the good work!

    This is my website :

  • Bruno Carreço

    @srinu, star ratings for users are only displayed on
    author pages. Visiting your site I can see it is indeed working on author pages:

  • sreenubfa

    Hello Bruno Carreço,
    Could you please help me. Star rating how to add right side user info bottom. I was trying many more times PHP Shortcode but not working.

    i have add link for required screenshot :

  • Bruno Carreço

    @sreenubfa, please post your request in the StarStruck forum. From there the support team will be able to assist you better and maybe provide you with a code snippet.

  • Gino

    is it possible to allow our visitors or users after buy an ad to rate the author. in classipress theme child

    • Bruno Carreço

      @Gino, I presume you are referring to a review system like Vantage and HireBee provide where buyers can review authors after each purchase, based on their experience with the author.

      StarStruck works a little differently, it allows visitors to rate authors at ANY time, but not on an ad basis. Meaning that when a visitor is rating an author it is doing it based on the author global quality. Visitors won’t be able to give different rates to the author based on each purchased ad.

      With StarStruck you gain the ability to allow users to rate ads at anytime similar to a ‘Like’ button.

  • joloshop

    It´s just not working if i click the rating an refresh the page there is still no rating see example

  • Robert

    Is there anywhere to see a demo of the plugin?

    • Bruno Carreço

      Robert, there’s not demo page for StarStruck but you can actually see it in use through our site on blog posts.

      As an example take a look at the stars ratings (after the main content) on the latest blog post.

      Anonymous likes this.
      • Robert

        Ok, I checked that out. Is there a way to display the average rating and number of votes (as the example post you sent me to does) and also display each person’s individual rating for that post next to their comment? Plus have a place for them to make their vote next to the comment input box?

        • Bruno Carreço

          That’s not currently possible. For that you would need some custom changes

          StarStruck allows users to vote on post types, authors or comments. So, if you add a voting option next to a comment it means that users are voting for that comment and not for the post that comment refers to.

  • joloshop
