When it comes to building error-free websites, structured data testing tools are an essential part of the web development process. 

Structured data designates specific elements on a web page, such as snippet boxes, company logos, job postings and videos. Schema markup is the coding language that allows search engines to read and understand this structured data, potentially boosting a website’s SEO performance and search engine rankings.

What Do Structured Data Testing Tools Do?

Structured data testing tools are designed to flag errors in organized data that’s 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 web page, 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.

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 can validate metadata formats supported by Google, Bing, Yahoo and other search engines. Structured data testing tools can also detect your permalink (or URL) setup and show information to search engines based on the structured data. Some can identify taxonomies and custom post types merely by evaluating their code.

 

How to Choose a Structured Data Testing Tool

There are a number of structured data testing tools to help you with your coding efforts, but some may be better suited than others, depending on your specific needs.

Different tools excel at compiling reports based on web metrics, cleaning up specific web pages and elements, reading various coding languages and accommodating both desktop and mobile formats

The makeup of your team may also play a factor in deciding which structured data testing tool to go with. If you have a team of programmers, for example, you may feel comfortable selecting a tool that is more code-heavy. On the other hand, non-technical personnel may prefer a tool that takes care of any coding-related tasks.

JSON-LD Playground

JSON-LD Playground helps determine whether your structured data syntax fulfills Javascript Object Notation (JSON) standards. JSON-LD, which is a fairly new structured data format, helps convert structured data that’s linked to a form that can be easily shared or stored and returned to its original structure when recovered. 

Teams simply plug in a URL or their structured data, and JSON-LD Playground delivers a complete report. This tool also shares examples of code structures for elements like recipes to give teams ideas for designing web pages. Because this tool is code-heavy, programmers or other personnel comfortable with different programming languages may be best at navigating JSON-LD Playground. 

 

Merkle Schema Markup Generator

SEO teams may find this tool especially useful for efficiently checking web pages and sites for errors and determining solutions for enhancing sites’ SEO performance.   

 

Schema.org

The Schema.org testing tool checks the rules defining the way your structured data is put together to ensure it meets all possible schema markup requirements. Teams add a URL or code snippet, and Schema.org analyzes it and adds the appropriate structured data. This tool also pairs well with different formats like RDFa, Microdata and JSON-LD. 

Webmasters may benefit the most from Schema.org. In addition to HTML, they can leverage Schema.org to implement different structured data vocabularies into their web pages, making their sites more readable for search engines. 

 

SEO Site Checkup Structured Data Test

SEO Site Checkup dishes out a comprehensive testing tool that analyzes your structured data to verify it meets HTML microdata extension specifications and suggests a priority for fixing the data errors and provides guide links to help fix them. Teams copy and paste their URL, then the structured data test analyzes the site to determine the state of its structured data. 

This tool uses HTML5 Microdata, so search engines can present search results in a way that allows consumers to find relevant web pages, making it a crucial tool for SEO personnel, programmers and web designers.   

 

Structured Data Linter

The Structured Data Linter tool verifies the structured data on HTML pages, processing microdata, RDFa and JSON-LD formats.

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 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.
