Schema has important implementations for both SEO and AI marketing. It unlocks features for products, reviews, images, and local searches, and can change how pages appear in search results. Information about a website included in schema markup becomes clear, unambiguous statements that can show up in search engines, knowledge panels, or AI systems (who currently struggle to understand the content).
Product schema markup allows pages to be included in Google Shopping by clearly providing details such as price and stock availability.
Structured data markup (schema) that includes images offers rich descriptions, enhancing image search results and improving page relevancy within web searches.
Including location, hours of operation, and other business details in structured data markup (schema) improves local search visibility and helps populate knowledge panels or other business-specific displays in search results.
"@id" Property
The "@id" property in schema defines a unique identifier for a specific entity. This allows search engines and AI-guided systems to unambiguously reference and connect data across different contexts or pages.
Improve Structured Data by Connecting Schema Entities with "@id"
Explains how the "@id" property resolves fragmented or unclear schema by explicitly linking brand-name entities to websites. It highlights why clear, unambiguous connections are crucial for machine understanding and sets the foundation for advanced structured data applications.
Structured Data Schema for AI-Aware SEO: Topical Pages and Hubs
Builds on connecting brand names to websites, showing how "@id" clarifies entity relationships in topical hubs or collection pages, manages keyword overlap, and illustrates real-world examples where semantic linking and entity hierarchy generate clear knowledge signals and stronger AI-aware visibility.
Schema in JSON-LD versus Microdata
Investigations into schema usage show that most structured data produced by websites is in the form of JSON-LD. Both JSON-LD and microdata have their pros and cons.
The following text box is an example of schema using microdata:
The following text box is an example of JSON-LD in a script block:
It can be noted that the JSON-LD script block provides all the schema in one location, whereas microdata has the information spread across the page. This difference can save time when making edits and ensures that HTML changes do not break the schema. Many sites use CMS systems, and if they are not designed to support microdata, changing themes can impact search and AI visibility.
Another point to consider is that when microdata is properly implemented, the content on the page matches the schema by default. However, when the content does not agree with the schema in a JSON-LD block, search and AI visibility can be negatively impacted.
The major difference between the two formats is that microdata uses an "itemscope" attribute for each block of data, whereas JSON-LD marks data blocks with opening and closing curly brackets. A "@context": "https://schema.org" declaration is also used in a JSON-LD block because these blocks can define other data contexts beyond Schema.org.
For example, certain schema properties can contain a nested block:
Using microdata, the "publisher" is a property with its own block and itemtype. Inside this block are two properties: a "url" and a "name". Each HTML tag is used as the container for the value.
Using "itemscope" with its value set to an empty string ("") ensures the property name is correct within each of these data blocks.
A "meta" tag can be used in cases an item property does not appear on the page, however an meta tag has no closing tag soe it can not be used with an itemtype and itemscope.
Modern SEO Goes Beyond Traditional Search Listings
Schema plays a crucial role in modern SEO by making content clearer to search engines and AI systems. It transforms information that might otherwise be ambiguous into structured data that is unambiguous and machine-readable. This not only improves how content is understood but also increases eligibility for enhanced search features like rich results, product snippets, and AI summaries.
Modern Image SEO Using Schema Structured Data
Image SEO today is about more than ranking for individual keywords. Images are integral to a page’s overall meaning and visibility. With AI-driven search, images help systems interpret and select relevant content more effectively. Schema markup, such as ImageObject, adds context that traditional signals like page titles alone cannot provide. While generic schema markup offers limited value, well-structured, context-rich schema improves understanding and visibility within search and AI guided search ... factors that significantly influence search performance in the modern SEO landscape.
Brand Entity Creation
The brand, organization, website, and author are all entities with relationships to other entities, such as products and services. Schema markup can be used to unambiguously state facts about the brand, which may appear in Google's Knowledge Panel, other areas of Google Search, and help associate brands or websites with specific topics.
Website and Organization Schema
Actual Site Name, Not Domain Name
About Page Description for Knowledge Panel
Byline published date and author
WebPage Schema
The WebPage schema defines details about the page, including its type, content structure, and supplemental resources it links to. Visual breadcrumbs not only assist with user navigation, but also help search engines understand the hierarchical relationships between pages on a website. In essence, WebPage schema contributes to the overall entity relationship framework of the site.
Schema: Content Structure and Supplemental Content
Realistic Expectations for Schema Markup
While structured data enhances the interpretability of a page, it is not a silver bullet for SEO. Search engines evaluate content within the broader context of the site, including its topical authority and historical association with the entity. A page snapshot may not fully convey the intended meaning or relevance in context. Schema can help communicate contextual intent, potentially influencing rankings positively, negatively, or not at all.
Negative effects are often the easiest to observe. It’s important to understand that systems interpreting JSON-LD schema data may adopt a “trust but verify” approach. While schema can guide how content is processed or highlighted, it is not authoritative on its own. Discrepancies between on-page content and structured data can lead to a loss of trust and reduced visibility in search results.
Structured Data Enables Search Features
Some schema types can enable enhanced search features, (such as review snippets, product listings, FAQs, or event cards), but inclusion is not guaranteed. Search engines determine eligibility based on the quality, accuracy, and relevance of both the structured data and the visible page content.
Solution Smith Testing Protocols
Solution Smith tests SEO and guided AI search the same way it tests software -- methodically and with evidence. If a feature is claimed, it gets tested. Observations begin as anecdotal data points, which are then verified through repeated experiments.
Solution Smith does not rely on Google to confirm or deny findings -- in fact, it’s expected that Google and other search engines won’t publicly disclose the inner workings of their algorithms.
