How to Exclude Structured Data on certain Posts

Of course you can exclude Structured Data on certain posts (pages and custom post types), too. It’s super easy (see down below). However I would not recommend to use this functionality very often as it messes up your ruleset-metabox and therefore it quickly gets very complicated.

How to use stamped.io ratings in Structured Data with SNIP

A customer asked how he can use stamped.io review ratings for an AggregateRating for his WooCommerce products. Here is how it works:


As far as I know you need to use stamped.io’s WordPress Plugin. It fetches all the ratings from their API and buffers it into the WordPress post meta database table. SNIP can access this data.

First of all you need to follow the example on how to work with custom fields. The configuration of the AggregateRating schema is a little different.

You can use the following values:

  • ratingValue: Post meta field “stamped_io_product_reviews_new->rating”
  • bestRating: Direct Text Input “5”
  • reviewCount: Post meta field “stamped_io_product_reviews_new->count”
  • worstRating: Direct Text Input “1”

That’s it! Have fun! 😉

How to deactivate JSON+LD schema output of “The Events Calendar” plugin

Google and other search engines are working heavily on schema.org integration. In the past, a lot of theme and plugin authors have integrated schema.org in their plugins but could not keep up with the speed of changes. So what I see happens a lot is that plugin and theme authors do not update their code accordingly. This is the case with the The Events Calendar plugin, too. It is missing some fields search engines want to see.

Does the plugin add content to each website page?

The answer to this questions (obviously) is yes as we have to output readable structured data so that search engines can read it.

However the data that is outputted is not visible to the end user. It’s only readable by search engines.

If you would view the sourcecode of one of your pages, you would find lines starting with something that looks like this:

<script data-snippet_id="snip-59a6a8000b284" type="application/ld+json">...</scrtip>

The data that can be found between these lines is the actual structured data that is formatted in JSON+LD format.

How to tell search engines which of the snippets is the main snippet on a page

As you may know it’s possible to have multiple snippets on one page. However this may cause side effects. Especially if you’re using multiple snippets that can create a Rich Snippet on search results. Let’s say you have a blogpost that generates the following snippets:
