Schema App Structured Data


What Markup does Schema App WordPress Plugin Create?

The Schema App WordPress plugin automatically creates markup for all your pages, posts, author and category content leveraging information that already exists in your WordPress website. Just activate the plugin, add your logo and the name of your business, and your content is optimized to be fully understood by search engines resulting in higher traffic, higher click-through rates and more. The plugin also provides all three Google Site Structure features including Breadcrumbs, Sitelinks Searchbox and Your Site Name in Results.

What type of markup is automatically created with this plugin?

  • Page :
  • Post :
  • Search :
  • Author :

  • Tag :
  • Blog :

Customization of Page and Post schema markup can be done through default settings (e.g. posts can default to NewsArticle) as well as by directly editing the generated JSON-LD for each page.

Google’s Powerful Video Features are added automatically for all videos hosted by YouTube and Vimeo.

I have installed this plugin on the recommendation of Neil Patel, wathing a youtube video of his Channel. He recommended to use this pluging for best result. I know the coding, but I wanted to save my time. So I donloaded this plugin. But it is a premium plugin, hence I want to delete this. But I couldn’t Delete this plugin. It Shows error. The worse plugin I ever downloaded on my wordpress website.

YOu have to sign up for a „free“ 14-day trial then if you don’t cancel you will be charged every month.

This plugin helped me to have a proper result in the Google structured data testing tool. Before, I have duplicates of structure data before I had errors. Then, I installed this plugin and everything is gone. Theme authors never accurately implement Structure data. SEO plugin authors never accurately implement structure data.

Needing an account for this simply is not acceptable. We do not need another club hoarding our data.
