How to fix bugs found with testing tools

If you encounter errors when testing structured data, fixing them is critical to ensuring your site appears in the SERPs. Many structured testing tools offer advice on how to eliminate errors in structured data, and below we’ll cover some key steps to remember.

1. Fill in the missing fields.

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

Missing: release date

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

2. Prioritize those with the most errors.

After testing structured data, your tool may alert you to the types of data that contain the most errors. You need to fix these first, as bugs in them can lead to subsequent bugs that will resolve themselves once those bugs are fixed.

3. Repair manual operation.

Manual action is when a human reviewer determines that pages on your site do not comply with Google’s webmaster guidelines. For example, a page on your site uses standard comment markup, but does not contain any comments. You need to fix these errors immediately, as manual actions can significantly affect your website rankings.

Structured data helps your website SEO

You should consider testing and validating your site’s structured data as a key part of your SEO process, as it has a significant impact on your site’s appearance in search results. Make sure your structured data is compliant with the structured data testing tools on this list.
