Why You Should Add Structured Data To WordPress Websites

Adding schema markup enhancements to websites is still somewhat new. Structured data, if done right, can boost your SEO performance dramatically. If you have not yet optimized your website with structured data, you can find a useful guide to getting started here.

1. How To Find Structured Data Errors In Your WordPress Website

Before you can fix your structured data errors you need to first find them. There are several free online tools to help you find any structured data and schema markup errors or warnings in your website.

Google Search Console

The first step is to check for structured data errors in Goggle Search Console. When Google indexes your pages it will show any errors or warnings it detects in Google Search Console.

Note: If you have not yet set up your website with Google Search Console, you can do so with Google’s “Getting started, for beginners” guide in a few easy steps.

Look under “Enhancements.” In the example below, there were several errors related to breadcrumbs structured data on our website. If you click on the errors, you can find out what the errors are and which pages or posts are affected.

Google Search Console For Finding Structured Data Errors

Google Search Console is a great place to check for ongoing structured data errors across your website. It is a good idea to periodically look here for the overall performance of your website too. Or set up automated email notifications to notify you if any issues are detected.

Once you know which pages are affected and have structured data errors that need to be fixed, you can find out where the errors are with the two online tools described below.

Google Rich Results Test

Another place that will test for structured data errors and help you fix them is Google’s Rich Result Test. Actually, before you publish your page or post, it is best to check for structured data errors here first.

Enter URL To Test Structured Data

Enter the URL of the page which you need to check or fix structured data errors on and click on the orange “Test URL” button.

Google will analyze the structured data on that page and provide you with a list of what types of schema it detected and if there are any errors.

If you click on the arrow next to any errors, you will be able to see what they are.

Enter Code To Test Structured Data

If you have access to the structured data code on your page you can also directly test the entire code in the Rich Results Test. Choose the “Code” option. Then copy and paste in you code in the box and hit the orange “test Code” button.

The results will look something like this:

From the screen shot above you can see that testing your code directly if more informative. The results from this tool will show you exactly which fields have errors and where exactly in your code they are.

Google Structured Data Testing Tool

You can also check for structured data errors using Google’s Structured Data Testing Tool. Overall, what you get from this tool is very similar to the Rich Results Test from the previous section. You don’t really need to use both.

As with the Rich Results Test it is self-explanatory to you. Paste in the URL of your page and hit the green “Run Test” button.

Google’s Structured Data Testing Tool: Fetch URL

Or use the “Code Snippet” option and paste your JSON-LD code in or you can paste in the URL of your website page or post.

Google’s Structured Data Testing Tool Code Snippet

Google’s structured data testing tool will review the structured data it finds on the URL you provide or it will analyze the structured data code you pasted in. In the examples used here it found two errors and three warnings.

Find And Fix Unparsable Structured Data Issues In Google Search Console

Unparsable structured data errors are those related to the syntax of your schema code. Because of these errors Google and other search engines cannot understand (parse) you structured data. Here is a link from Google that lists the common syntax errors found in structured data.

You can find these structured data issues, if they exist, in Google Search Console. But the “Unparsable structured data” report is not always available in your normal view. To access the report for your site on Google Search Console, click this link.

You will now see it on the bottom left (circled below). If there are no errors, nothing will show up in the report. But if you see any,

If you have unparsable structured data errors, you can find out more about each error, which pages are affected, and suggestions for how to fix.

Google’s Rich Results Test For Fixing Structured Data Errors

Google’s Rich Result Test will also let you find the structured data errors on your pages by highlighting them for you as shown below. You can then make the changes and fix/test the errors in the same screen.

Both these tools from Google are good to fix structured data errors that are minor, such as missing syntax. But if you have significant items missing from your markup or more serious errors that are preventing your rich results from showing up, then you will need to address them with some of the approaches below.

Not all schema markup types are currently supported in Google Console. In the example above, breadcrumbs, the sitelinks searchbox, and logos were detected. The article schema that was also included did not get picked up. Google does not currently support article schema in its console.

However, it is still active and will appear as rich results. The main test if whether your schema markup is detected in the Structured Data Testing Tool. If it is picked up there, you are all set and don’t need to worry about what shows up in the search console.
