Add Rich Snippets to your website using Structured Data (schema.org)

What are rich snippets?
A rich snippet shows extra information between the URL and the description in Google search results. For example, if you search for 'Strawberry Milkshake', then Google may include rich snippets in the search results like this:
Example
One of the most commonly used schemas is 'Product'.

Select 'Product' in the 'Type' property. Note that the other properties are updated based on this selection.
Now you can enter a brand name (for example, company name), product name, a description of the product and other values.

For example:
Brand: Pablo Software Solutions
Product Name: WYSIWYG Web Builder
Product Image: http://www.wysiwygwebbuilder.com/images/screenshot1.jpg
Description: Visual, drag and drop web design tool
Product Number Type: WWB
Rating: 5
Rating count: 999
Price: 59.99
Price Currency: USD
Item condition: http://schema.org/NewCondition
Customize Structured Data (for advanced users)
WYSIWYG Web Builder includes definitions for frequently used schemas. It does not include all possible properties because we think that would make the tool too complicated for 'standard' users. However, it is possible to modify the schemas yourself. The definitions are loaded from the file 'richsnippets.json' in the Program Files folder in JSON format. This file cannot be modified in this location because the file is protected by Windows. But you can create a customized version of the file by copying it to the Documents\WYSIWYG Web Builder\system folder. In that case WWB will load the customized  file instead of the default version.

Be careful when editing the file, because even the smallest mistake in the code (like a missing comma or quote) may impact the functionality.

Note that this is just a basic tool to help you quickly add structured data to your web pages. It does not validate the data you have entered. The Google Structured Data Testing Tool can be used to validate the structure of data:

Each schema has different values. In most cases, when you select a property the tool will display a hint for the expected value in the description field. For example, if you select 'Price Currency' then the description field will display 'USD, EUR, GBP'.

Notes:
Don’t place ratings on your homepage. Google states: “Review and rating markup should be used to provide review and/or rating information about a specific item, not about a category or a list of items. For example, “hotels in Madrid,” “summer dresses,” or “cake recipes” are not specific items.

Make sure the rating values are realistic. Using 5 star ratings for all your products may not be believable.

Even after adding structured data to your pages, it is up to Google if your data is visible or not.
Also note that it may take a couple days (or weeks) before Google finds the structured data on your website.

Remember that you should not provide incorrect meta data for Google, otherwise it may have negative impact on a website's search rankings. So whatever you do, don’t forget to test your the page with the Structured Data Testing Tool: https://search.google.com/structured-data/testing-tool/u/0/

This is a relative new tool for WWB, so we will continue to improve this functionality in future updates based on user feedback.
In this snippet, a picture of a milkshake is added, you can see the rating of the recipe, the time it takes to prepare the milkshake and other information.

Why are rich snippets useful for SEO?
Rich snippets stand out from the other search results. They look nicer, the user will instantly know more just by looking at them, and they have a higher click-through rate.
