Does structured data really improve visibility in AI overviews?

The way you and I find information online is currently experiencing its biggest revolution in a decade. It’s a well-known trend that a large portion of all Google searches end without a click on an external search result. The new, AI-generated answers right at the top of the search results – known as Google AI Overviews – significantly amplify this development and present you, as a website operator, with a crucial question: How do you stay visible?

The recently published article by Searchengineland was an exciting read for me because it confirms a suspicion I’ve had for a long time and that I consistently implement here at seo-kreativ.de. I have always been firmly convinced that structured data must gain importance in a data-driven future of search. Today, we are seeing how search is reinventing itself with AI Overviews and the new “Google AI Mode” – and my own positive experiences seem to support this thesis.

In this article, I will show you why structured data is more important now than ever before and how you can use it as a decisive advantage for your visibility in the new era of Google Search.

AI Overviews are summaries created by artificial intelligence (AI) that attempt to answer a search query directly on the results page. Instead of just clicking on a link, you receive a prepared answer that combines information from multiple sources.

This new feature fundamentally changes search engine optimization. If you want to dive deeper into the technical background, I recommend my detailed article on the functionality of Google AI Overviews. The strategic question for you is: How can you influence the AI? The answer lies in the language that machines understand best.

Structured data is a standardized code format that you add to your website to give search engines explicit clues about the meaning of your content. It is essential to adhere to Google’s general guidelines for structured data.

Think of it this way: Without structured data, Google sees an image of a product and tries to guess what it is from the context. With structured data, you give Google a detailed label that says: “This is a product. Its name is ‘XYZ’. It costs €19.99. It has a rating of 4.8 stars from 50 users.”

This code, often implemented in JSON-LD format, translates your human-written content into a machine-readable language. The vocabulary for this comes directly from schema.org, a joint initiative of the major search engines.

Although Google has not officially confirmed it, all signs point to structured data playing a crucial role for AI Overviews. The connection is not direct, but absolutely logical.

From Ambiguity to Clarity: Why AI Loves Facts

AI systems hate ambiguity. They are designed to create trustworthy and fact-based summaries. Structured data eliminates this ambiguity. It provides the AI with clear, unequivocal entities (like a person or a product) and their attributes (like a name or a price). By clearly structuring your content, you make it a perfect, trustworthy source for the AI.

Structured Data as a Strong E-E-A-T Signal

The concept of E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) is the foundation for Google’s quality assessment. Structured data is a technical means to substantiate your E-E-A-T. For example, by clearly defining who the author of an article is using Person or Organization schema, you provide Google with verifiable facts about your expertise. You can find more on this in my ultimate E-E-A-T guide.

What the Industry Says: A Look at Searchengineland’s Analysis

The analysis by Searchengineland confirms this strong correlation. The experts there agree: Even though there is no guarantee of appearing in AIOs through Schema Markup, it significantly increases the probability. It makes your website a “better, more reliable, and easier-to-understand source” for the AI.

The theory is clear, but where do you start in practice? I recommend focusing on the schema types that offer the greatest contextual value to the AI:

• FAQPage: Mark up frequently asked questions and their answers. This is a goldmine, as AI Overviews often answer direct questions.
• HowTo: Ideal for tutorials. The AI can directly integrate your step-by-step instructions into its results.
• Article / NewsArticle: A must for every blog post. Define the author and publication date to strengthen your authority.
• Organization: Clearly define who is behind the website, including logo and contact details. This builds trust.
• Person: If you present yourself as an expert, use this schema for your author or “About Me” pages.
• Product: Absolutely essential for e-commerce. Prices, availability, and reviews are critical data points for the AI.
• BreadcrumbList: Helps the AI understand the structure of your website. Note that, according to Google’s own statement, only the domain is often shown on mobile devices. However, the full markup remains essential for the AI’s understanding of the site hierarchy.

A Look into Practice & My Strategy at seo-kreativ.de

Theory is good, but practice is crucial. As mentioned at the beginning, at seo-kreativ.de, I have always consistently focused on a clean implementation of Schema Markup for all my content. I do this out of the firm conviction that it is the most logical and effective way to communicate clearly with search engines.

A perfect example of this is my English blog post about the discontinued num=100 parameter. It is prominently featured in the AI Overviews for the search query “google num 100 disable”. When I analyzed the sources used for it, my strategy was confirmed.

The analysis of the sources shows a clear pattern. Here is an excerpt of the pages I examined:

You see the common thread: A combination of Article, Organization, and Person is almost always present.

But - and this is an important point - in other analyses, I have also discovered pages in AI Overviews with no structured data at all. However, these usually have other strong authority factors, such as high domain authority or an excellent backlink profile.

Therefore, my conclusion from practice is: Don’t rely blindly on structured data alone. It is an extremely powerful lever to create context and trust and to massively increase your chances. But always consider it as part of a holistic SEO strategy that also includes building authority and creating outstanding content.

The SEO world is in a state of flux. While others are still debating whether AI Overviews are an opportunity or a threat, you can already take action. With the new “AI Mode” from Google, the development is moving even further towards a conversational internet. Structured data is no longer an esoteric SEO tactic – it is the fundamental necessity for communicating with modern, AI-driven search engines.

It is your ticket not only to be present in the new Google Search but to be perceived as a trustworthy and authoritative source. By investing in clean Schema Markup, you are investing directly in the future visibility and authority of your website.
