How to Fix Errors Found With a Testing Tool

If you get errors when testing your structured data, fixing them is crucial to ensuring your site shows up in SERPs. Many structured testing tools give suggestions on how to remove the errors in your structured data, and below we’ll go over some critical steps to remember.

1. Fill in missing fields.

Some of the most common errors you may see are missing fields. This usually means that you have an element in your structured data that doesn’t have a corresponding field that explains what the data is. For example, if you're missing a publish date in the structured data for a news article, you may see:

Missing:date published

You can simply fix this error by entering the publish date.

2. Prioritize those with the most errors.

After testing your structured data, your tool may call attention to the data types that contain the most errors. You’ll want to fix these first, as errors in these may be contributing to subsequent errors that will resolve themselves once these are fixed.

3. Fix manual actions.

Manual actions are when a human reviewer determines that pages on your site aren’t compliant with Google’s webmaster guidelines. For example, a page on your site uses the standard review markup but doesn’t include any reviews. You’ll want to address these errors immediately because manual actions can significantly impact your site rankings.

Structured Data Helps Your Site SEO
