What Do Structured Data Testing Tools Do, Exactly?

Structured data testing tools are software tools designed to flag errors in organized data that’s been arranged in repositories, like databases, and provide insight on how to resolve issues, as well as tweak the data to get the best performance out of it.

The benefit of structured data, versus semi-structured or unstructured data, is that it’s easier to manipulate and query since it’s organized or structured for a specific system or purpose. Often that purpose is to communicate information about a webpage, such as a logo, contact information, rich snippets that contain additional information about website content on search page results, or other information that may come up in search results.

What Do Structured Data Testing Tools Do?

These software tools are designed to identify bugs in structured data so you can fix them, as well as optimize the data, before you deploy a website.

Structured data testing tools are especially useful when it comes to creating data, such as metadata, to create website page information discoverable by search engines. 

These tools, for example, can validate metadata formats supported by Google, Bing, Yahoo and other search engines, according to a Software Testing Help blog post. Structured data testing tools can also detect your permalink, or URL, setup and show information to search engines based on the structured data, while other structured data testing tools can identify taxonomies and custom post types merely by evaluating their code.

There are a number of structured data testing tools to help you with your coding efforts and reduce your frustration levels.

JSON-LD Playground

Merkle Schema Markup Generator

Microsoft Bing Markup Validator

This structured data testing tool, which is part of Bing Webmaster Tools URL inspection tool, is especially useful when perfecting your site for Microsoft’s Bing. With this tool, you’ll not only find markup errors in your structured data but also receive suggestions on how to improve the data’s organization.

Why Structured Data Testing Tools Are Important

Structured data testing tools are a key component of an SEO strategy

One error in your structured data, such as missing or wrong code in your markup, can prevent search engines from finding your information and displaying it in its results.

That, in turn, could potentially cost your company lost customers. Structured data can contain such information about your company’s product pricing and features, or perhaps, its customer ratings, but errors in your structured data may prevent that information from surfacing when a potential customer does a search.
