10+ Structured Data Testing Tools

In the structured data markup implementation, it’s important to stick to one rule: one step at a time. To avoid any missteps in Google’s understanding of your markup, check it before placing it on the page to see what possible issue may occur and what needs improvement. In this blog post, I recapped the tools that you can use yourself or with the help of the devs team.

Why Testing Structured Data?

Even though Google does not confirm that structured data implementation is a ranking factor, its presence brings such goodies as:

  • Search engine robots can better navigate through the content on the page and gather information about it because with the addition of structured data markup, the site’s HTML code becomes neat, understandable, and ‘structured.’
  • Markup can become a display feature for a snippet.
  • It helps reduce the bounce rate. At least, indirectly. But if all necessary information is displayed in a snippet, such as a price, picture, date, star rating, breadcrumbs, etc., a searcher will know what exactly they’re looking for on a landing page.

Double-check structured data markup for errors before deploying on the page using structured data testing tools. If there are any issues with structured markup Google won’t read it, because it’s a mess. Testing tools show you what kind of errors are detected and how you can fix them.

These errors can easily go unnoticed for a human eye, so testing the structured data with different tools is an annoying stopover that can save tons of time in the future.

Top 10 Structured Data Testing Tools

So to test the code for any error, you need to choose the right tool that fits your purpose. To tell you the truth, there is a huge variety of these tools on the market, so it can be puzzling at first to make up your mind. We rolled up our sleeves and gathered these ten tools to point out their major shines and drawbacks.

1. Google Structured Data Testing Tool

Google Structured Data Testing Tool

The show opens with a Structured Data Testing Tool developed by Google. It’s easy to use. You simply have to put a URL with a schema markup or a code snippet. The tool will test your structured data and pitch if any issues are detected or give recommendations on how to advance markup. The tool helps to validate JSON-LD, Microdata, and RDFa structured data formats.

Another boon – the tool will check and show you the fields of structured data such as the name of the organization, it’s URL, type, and more.

Hallmarks:

  • It validates JSON-LD, Microdata, and RDFa structured data formats
  • It’s completely effortless to use
  • It’s free

2. Chrome Extension: Structured Data Testing Tool

Chrome Extension: Structured Data Testing Tool

This extension is another no-sweat way to validate structured data. The ‘insides’ of this tool are clear as day – it pulls data from Google’s Testing Tool to check JSON-LD, Microdata, and RDFa structured data formats. Likewise, it highlights red and orange issues that need improvement.

The tool can assess the websites when they’re staging to validate schema markup.

Hallmarks:

  • It’s easy
  • It’s free
  • No need to copy paste URLs or code

3. SEO SiteCheckup

SEO SiteCheckup

This tool is suitable for HTML structured data validation. Also, it has guides on how to fix issues in microdata and how to use HTML5 microdata on your contact web page.

Despite being handy in markup testing, it also suggests the website analysis features. It’ll check your website for SEO issues such as page load speed, URL redirects, nested tables, broken links, mobile responsiveness, and much more.

Hallmarks:

  • It has a 14-day free trial
  • It has three plans, the middle one costs 39.95/month
  • It generates custom reports (white-label feature)

4. Netpeak Spider

So to add salt to a conversation about third-party tools that have a structured data testing feature, it’s worth mentioning Netpeak Spider crawler. This tool has dozens of features and built-in tools (such as Page Rank calculator, Sitemap Generator, Source code and HTTP header analyzer, and much more) that are irreplaceable for a comprehensive website audit.

Among other things, you can detect structured data on pages, its formats (JSON-LD, Microdata, RDFa), and types. If you need the validation of structured data, you can open Google Structured Data Testing Tool directly via the program.

Hallmarks:

  • It has a 7-day free trial
  • The price starts at 19/month
  • It has a white label feature and integration with Google Drive (you can export ready-made reports straight to cloud storage)

4. JSON-LD Playground

JSON-LD Playground

JSON-LD is the newest structured data format, but it already gained its acclaim. The tool helps to check whether the syntax meets requirements.

You enter the markup code or URL of the remote document and receive a detailed report for a thorough closeup.

Hallmarks:

  • It’s free
  • It’s best for validating JSON-LD structured data formats

5. RDF Translator

RDF Translator

This tool gives an opportunity to test a vast range of structured data formats: from RDF/XML to RDFa or Microdata. It’s particularly useful for validating XML, N3, and N-Triples structured data format as many free tools don’t support them.

Besides, it allows developers to incorporate the tool on the website because it comes with the REST API.

Hallmarks:

  • It’s free
  • Allows for conversions triggered either by URI or by direct text input
  • Can be incorporated on the website

6. Structured Data Linter

Structured Data Linter

The tool validates RDFa, JSON-LD, and microdata according to the latest specifications. However, this tool doesn’t support microformats at the moment. It helps verify the structured data present in HTML pages and will provide a rich snippet visualization.

An unusual thing about this tool is that despite traditional pasting URL or code, you can upload a file with code, which means even a rough draft of structured data can be tested in this tool.

Hallmarks:

  • It’s free
  • You can visualize a rich snippet

7. Microdata Tool

It’s good to be familiar with microdata syntax, but even better to know that this format is a rare creature and occasionally used now. Microdata Tool can validate HTML5 microdata structured data.

The tool is a jQuery drop-in script that you can include on your website, which can be used without any internet connection or web server.

Hallmarks:

  • It’s free

8. Schema Plugin for WordPress

Schema is a quick fix to most structured data needs. It supports different schema.org types, customization of source data of schema.org properties, and also, it has data output for JSON-LD format, the most recommended by Google. Note that expansive Schema markup via plugins may fail to be recognized by Google.

Hallmarks:

  • It’s freemium – some features are free, but premium ones start at 99$ per year
  • Some webmasters tentatively recommend using this plugin since it entails many issues afterwards

9. Bing Markup Validator

This tool goes beyond the Google realm – it’s a part of Bing Webmaster tools. It lets you validate the different types of structured data, including RDFa, JSON-LD, OpenGraph, and microformats. However, it won’t let you verify the HTML structured data.

To start, you have to sign up and add your site to validate the structured data code.

Hallmarks:

  • It’s free
  • Requires additional fuss with login

10. Yandex Structured Data Validator

Yandex Structured Data Validator

It supports microformats, Schema.org, Open Graph, HTML microdata, and RDFa. It also checks whether the markup meets the Yandex’s requirements. Likewise other tools it suggests to paste URL or HTML code into the bar and receive the results on markup with the ‘Error,’ or ‘Warning’ notes in case any issues are detected during testing.

Hallmarks:

  • It’s free
  • You can get API that automates validation of semantic markup

11. Google Email Markup Tester

Google Email Markup Tester

You can empower your emails with schema.org markup. And to verify whether the structured data extracted from email documents meet the standard specification or not, go and paste the markup code in the text box. The tool will display the extracted structured data along with the properties for every entity. If the input is not valid, the tool will point out errors.

Hallmarks:

  • It’s free
  • It’s hellishly easy

In a Nutshell

Organic search is getting increasingly competitive. Structured data deployment is yet another way to win the game. Before deployment, check it for possible issues in a testing tool since a single mistake can lead to an obvious outcome: neither Google nor other search engines will recognize your structured data markup.

Google Structured Data Testing Tool perfectly suits the validation of basic markup formats. For a more in-depth analysis of a broader range of formats, go for RDG Translator, JSON-LD Playground, or Structured Data Linter.

If you’re looking for a multi-purpose SEO tool, which includes structured data testing (or detection) feature, I recommend using Netpeak Spider or SEO SiteCheckup.
