We call them rich snippets, and the secret behind them are Schema Markups. Schemas may sound like new technology, but they’ve been around for over a decade. Besides providing a better understanding of a webpage’s content, they drastically improve organic CTR from any SERP.

This article explains rich snippets, schema markups, structured data, and why you should incorporate them.

Content

What is schema markup?

Schema markup is a type of code (semantic vocabulary) that you add to your web pages to help search engines return more useful results to users via rich snippets. Here’s an example of schema markup in an article and what it looks like on Google’s SERP.

What is the significance of schema markup?

Rich snippets, often more clickable than regular search results, appear because of schema markup. This means more searchers will visit your website, hence boosting your CTR rate. Google will also rank your website higher if it notices that your organic CTR rate from its SERP is higher than other websites ranking for the same keyword. So in a way, schema markup indirectly helps your SEO case.

Significance of schema markup for publishers

If you are a publisher – the significance of schema markup is crucial for your website. Especially if you have a personal blog, training courses, music depository, or online book store, rich snippets will allow your website to stand out and increase CTR even if you are not in the first lines of SERP.

For example, rich snippets will allow your article to look like that:

and not like that:

However, Schema markup’s primary purpose is to help search engines better understand your web page’s content.

Types of schema markups

The schema.org vocabulary contains data structuring formats for all types of people, places, and things on the internet. On schema’s website, you can find a complete list of items that schema markups can define.

Schema markups often indicate the following:

  • Articles
  • Blog posts
  • Creative Works
  • Reviews
  • Organizations
  • People
  • Products
  • Local Businesses
  • Recipes
  • Events

After you’ve added these markups to your site, the Google bot will be able to figure out what each webpage is about. Rich Snippets enable the search engine to display this information.

Here’s an example of a page that uses the schema markup for Events: we can see the dates and locations of various events have been marked up appropriately.

Here’s an example of a schema-generated review rich snippet:

Creative Works: an example of Schema AggregateRating.

Creative Works — a library of markups for creative content such as movies, books, video games, and music — is a popular branch of the schema vocabulary.

Here’s an example of what the “Movie” markup shows on Google’s SERP. It’s worth noting that it includes movie-specific information such as the rating, genre, and release date.

You can use RDFa, Microdata, and JSON-LD to implement these markups.

What are RDFa, Microdata, and JSON-LD?

These are all code languages that can be added to HTML in order to embed metadata (such as schema) in a web document.

  • RDFa is an acronym for Resource Descriptive Framework in Attributes. It’s a type of code that can be used in HTML, XHTML, and XML documents.
  • Microdata is a compact superstructure over the usual HTML markup, is a logically related set of “name-value” pairs, and is based on the content of a web page.
  • JSON-LD stands for JavaScript Object Notation for Linked Data; it is an uncomplicated way of transferring data linked to each other.

Insert the code on your website

There are several ways to mark up the webpage’s content:

  • Manually (to do this, you need to understand the code at least at a basic level).
  • Using Google Tag Manager.
  • Using CMS plugins.

Manually

The JSON-LD script can be placed anywhere on the page. This is done in the source code editor in a few seconds. Microdata is more complex – you will have to search for the same fragment of content marked up and change it to the generated code or assign each attribute for existing tags separately.

Google Tag Manager

This is a Google system that allows you to manage JavaScript and HTML tags on a website without the participation of developers.

To create structured data using Google Tag Manager, follow these steps:

  1. Install and configure Google Tag Manager on your site.
  2. Add a new custom HTML tag to the container.
  3. Insert the desired block of structured data into the tag.
  4. Install the container. To add a tag to a site, place the container in the Google Tag Manager interface.
  5. Perform testing.
Using a CMS and plugins

Popular CMS plugins allow you to generate and deploy schema markup directly in the website control panel (immediately when creating or editing pages or plugin settings).

There are many options available. If your site uses WordPress, there are specialized plugins and separate modules as part of SEO plugins. There are often problems with modules since they do not correctly deploy the markup.
