We recommend the Schema App Structured Data WordPress Plugin for users who want to add image schema markup to their WordPress site images. This plugin automatically creates and deploys the default Schema.org Markup for your pages, posts, author, and other types of content on your WordPress site, which can help your site stand out in search and get more clicks and conversions.
The plugin supports various types of default Schema Markup, including Article, BlogPosting, SearchResultsPage, ProfilePage, CollectionPage, Blog, BreadcrumbList, and WebSite. It also automatically adds Video Schema Markup for all YouTube Videos embedded on your page. You can customize your Page and Post Schema Markup through the default settings or by directly editing the generated JSON-LD for each page.
If you need more than just default Schema Markup for your WordPress site, the plugin also offers an end-to-end custom Schema Markup solution, which includes access to the Schema App Editor and Highlighter, an assigned Customer Success Manager, and the development of a reusable content knowledge graph. This solution can help you generate custom Schema Markup to describe your website content in detail and develop a reusable content knowledge graph that drives quality traffic to your site.
