Schema Package – Structured Data & Rich Snippets Tool for SEO vs Smush – Image Optimization, Compression, Lazy Load, WebP & CDN

It achieves this by integrating with plugins or themes that generate content, ensuring compatibility and automation.

It does not guarantee that your content will appear in search engine results as you desire. It entirely depends on the Search Engines. Here are some schema and structured data markup validator tools that can help you validate and troubleshoot your markup: 1. Google Rich Results Test The “Google Rich Results Test” does not validate all types of schema.org markup. It is primarily designed to test the types of schema markup that can generate rich results in Google search, such as Product, Recipe, Event, FAQ and others related to search features. While it can validate whether your structured data is correctly implemented for rich results, it doesn’t support every schema.org type. For example, it may not check more general types like Service, Organization, or CreativeWork, unless they are directly relevant to a rich result display. 2. Schema Markup Validator The “Schema Markup Validator” by Google validates all schema.org types, not just those that are eligible for rich results. This tool checks whether your structured data is correctly implemented according to the schema.org specifications, regardless of whether the type is eligible for rich results. Important Note About LLMO (AI Search) AI search tools like ChatGPT, Gemini, and Perplexity currently do not provide official documentation on how they read or rank structured data. Unlike Google Search, the LLM ecosystem is still new and evolving. However, most AI platforms appear to rely on standard SEO signals, good content, clean site structure, and valid Schema.org markup. Schema Package focuses on generating high-quality, standards-based JSON-LD that helps AI systems better understand your content. Still, there is no guarantee that adding schema will directly improve visibility in AI search results. Our goal is simply to make your site technically prepared based on current best practices as the LLM landscape continues to grow.
