In this post, I will talk about some of the best free schema markup testing tools that you can use online. These are basically web apps that take a URL from you and show if there is schema markup applied in your website or webpages. If there is JSON-LD code on your webpages then it will show them to you. In addition, they can even validate the existing schema markup.

And in that case, you must verify that your schema markup is working and the websites I have listed here will help you do that. Here I will talk about 5 such websites that you can use to quickly validate an online webpage.
