Structured Data: What is Schema Markup and How Can It Help Your Website

There is an evolution happening in how search engines understand websites, but most firms in the AEC and professional services space may be unaware it’s happening. It doesn’t involve redesigning your site or overhauling your content strategy, but something more subtle; giving search engines and AI tools a more structured way to understand what your website is actually about.

That’s what schema markup is for. Right now, it’s one of the most underutilized tools available to firms that want to show up in search results, especially as AI-powered search experiences continue to change the game.

What is Schema Markup?

When someone visits your website, they read it the way a human would. They start with your headline, scan your copy and service descriptions, maybe read a case study or article. They can understand context and know that when your about page says “founded in 1998 in Charlotte, NC,” that means you’re an established local firm with decades of experience.

While search engines and AI tools are getting smarter, they still need a little help with this type of context. Schema markup is basically a layer of structured information added to your website’s code that tells search engines and AI tools exactly what they’re looking at. Instead of a search engine having to guess that a section of the page describes a service, schema markup clearly labels: this is a service, this is the name of that service, this is the geographic area it covers, this is how people can contact you about it.

It doesn’t change what your visitors see, but it changes how machines understand your site.

The vocabulary used for schema markup comes from a shared standard called Schema.org, which was developed collaboratively by Google, Microsoft, Yahoo, and Yandex. It gives everyone a common language for describing what different types of content mean on their website.

Why AI Search Makes Schema More Important

For a long time, schema markup was primarily talked about in the context of “rich search results,” which are the enhanced listings you see in Google search that show star ratings, FAQs, event dates, or other details directly on the search results page. Those are still relevant, but the reason schema markup is getting more attention now has more to do with how AI is changing search.

Tools like Google’s AI Overviews, ChatGPT search, Perplexity, and other AI-powered research assistants don’t just retrieve pages. They process information and pull from multiple sources, create answers, and present them in a way that doesn’t typically require a user to click through to a website at all. The companies that get cited or referenced in those answers are the ones whose content is easy for AI to accurately understand.

When your website uses schema markup correctly, you are essentially translating your content for the machines doing the processing and reducing the amount of guesswork. An AI tool trying to answer a question like “who are the top civil engineering firms in Charlotte” is going to find it a lot easier to identify and cite your firm if your website has used structured data that clearly communicates that you are a civil engineering firm located in Charlotte.

Keep in mind this is not a guarantee of visibility, because nothing in search is. But it greatly improves your odds, and in a way that most of your competitors have likely not bothered to take action on yet.

What Schema Markup Looks Like

Different types of businesses benefit from different types of schema markup. Here are a few examples relevant to the types of industries we work with:

Your Firm’s Core Identity – Organization Schema

The most foundational type of schema for any professional services firm is what is called “Organization” schema. This tells search engines your firm’s name, where you are located, how to contact you, what your website is, and what social profiles are associated with you. It sounds basic, but a surprising number of firms either have this missing entirely or have it set up inconsistently.

For firms with a physical office that clients visit, adding LocalBusiness schema on top of that further signals your geographic relevance, which matters a lot for searches with local intent.

Services You Offer – Service Schema

Service schema is markup designed specifically to describe your services. For an architecture firm, this could mean marking up individual service pages, whether it’s urban planning, interior architecture, or historic preservation, in a way that clearly connects each service to your company and explains what the service involves. For an engineering firm, it might mean labeling your structural, civil, or MEP capabilities in structured terms.

This kind of markup helps search engines and AI tools understand the full scope of what you do, rather than trying to piece it together from paragraphs of marketing copy throughout your website.

Projects and Case Studies – Project Schema

For AEC firms especially, project work is typically the most compelling content on the website. Schema can be applied to project pages to better communicate what type of project it was, where it was located, and what your firm’s role was. While there’ is’s not one single schema designed exclusively for construction projects, a combination of existing schema types, like the project schema, can be used to make this content more machine-readable.

People and Team Members – Person Schema

If your company’s reputation is tied to your principals or key staff members, Person schema can help establish those individuals as authoritative figures in their field. This is useful for firms where thought leadership and named expertise are part of your brand, which is increasingly common in architecture and high-end consulting firms.

FAQ Content – FAQ Page Schema

If you have FAQ sections on your website, there is a specific schema type for this. FAQ schema can be one of the more visible ways to get enhanced search results. Beyond rich results, FAQ content marked up with schema is easy for AI tools to pull into synthesized answers, which can get your name and perspective in front of people even if they never visit your site directly.

Common Schema Markup Mistakes

Schema markup is not all that difficult to implement, but it’s easy to do in a way that is incomplete or inconsistent.

The first is having no schema at all. A lot of firms, like those whose websites were built several years ago, have never added structured data. The website looks fine and performs well, but underneath the surface it is basically invisible to machines. Structured data can fix this.

The second is having schema that does not match the visible content on the page because search engines penalize mismatches. If your schema says your firm is located in one city but your contact page lists a different address, that inconsistency can create problems. Structured data needs to accurately reflect what’s on the physical page.

The third is using generic or template-generated schema that is not customized to your firm. Some content management systems add basic schema automatically, which realistically is better than nothing. But generic schema doesn’t capture the nuance of your services, your specializations, or your geographic markets in a way that gives you a competitive edge.

How to Think About Schema Strategically

Schema markup is not a one-time fix, but is an ongoing layer of your website’s infrastructure, and it should evolve as your company evolves. When you add a new service, that should be reflected in your structured data or when you move offices or add a new location, the same logic applies.

The firms that benefit most are the ones that treat schema as part of their broader content and SEO strategy rather than a technical box to check once and then forget about. That means auditing what you have, identifying gaps, and making deliberate choices about what schema to add and why.

You should also pay attention to how AI search behavior continues to develop, because the landscape is moving incredibly fast. Google is constantly updating how it surfaces AI Overviews and tools like Perplexity are growing in usage among the professionals who hire firms like yours. Being ahead of this curve can matter in terms of whether your firm gets found, seen and remembered.

What This Means for Your Company

If you’re a CEO or marketing leader at an AEC or professional services firm, our practical takeaway is this: your competitors are likely not prioritizing structured data. Most firms in your industry are probably still focused on the more visible elements of their website, things like redesigns, photography and content. And those things matter. But the invisible layer of how search engines and AI tools understand your site is a real, mostly unclaimed opportunity.

It’s important to keep in mind you don’t need to understand the technical details of how schema is written. You need is a web partner who does, and a clear understanding that this is an area worth investing in. The payoff is not always immediate or dramatic, but cumulative. Every part of your website that becomes more readable to machines is another step toward showing up in the right places and in front of your ideal customer base.

And that’s a competitive advantage that compounds over the long-term.
