Slim Seo Schema Premium gpl is the best way to describes structured data for search engines. Based on the data provided, search engines can show the content in the search results page in a more appealing way.
Slim SEO outputs schema data via JSON-LD in a single <script>
tag in the footer. The plugin also provides connections between schemas. Connections are important because it gives search engines a lot of information for not only the main content of the web page, but also related information, which help them understand it deeply.
For example, if you’re on a single post, the plugin can tell search engines about the main entity of the page is an article, which has an author and belongs to a webpage of an organization. The webpage has a breadcrumb list, and belongs to a website, which has a search box. This way, search engines not only understand about the content of article, but also author, organization and the website structure.
