When visitors browse your website, they see the design, images, and text. Google sees only HTML. Without hints, it can’t reliably tell whether a number is a phone, a price, or just random data.
Structured data solves this problem. For businesses in the Czech Republic and the EU, it’s essential for two reasons:
- Stand out from competitors: Your search result takes more space and looks more compelling (ratings, product photos, FAQs).
- Get into AI Overview: Google’s latest AI systems use structured data as a trusted source when generating direct answers.
Think of your website as a library. Without a catalog (markup), the librarian (Google) struggles to find the right book. With a catalog, everything is found instantly and efficiently.
The most important markup types for businesses:LocalBusiness: Must-have for companies with a physical address (offices, cafés, salons). Displays opening hours, address, and phone. Perfect for local
one-page websites.
Product: Critical for e-commerce. Shows price, availability (“In Stock”), and rating directly in search. Without it, promoting an
online store in 2026 is nearly impossible.
Organization: Logo, social media links, customer support contacts. Helps form your Knowledge Graph panel.
Article / BlogPosting: Highlights publication date, author, and title. Helps blog posts get into Google Discover.
BreadcrumbList: “Breadcrumbs” that display your site structure right in the snippet, improving navigation before the click.
Implementation formatsThe modern standard is
JSON-LD. It’s a script invisible to users, easy for search engines to read, and doesn’t affect page loading speed.
Even experienced developers sometimes make errors that can trigger Google’s manual actions.
Markup of hidden content: Never mark up information not visible to users (e.g., fake reviews hidden in code).
Wrong data type: Marking a service as a “Product” or a blog post as a “Recipe.”
Ignoring validation errors: One missing bracket can invalidate all markup.
Plugin conflicts: A common WordPress issue when multiple SEO plugins output the same structured data.
We don’t use generic, checkbox-style solutions. For every project, we craft the logic manually or configure JSON-LD generation tailored to specific business requirements.
For corporate clients: We build complex hierarchies of Organization and Service, connecting offices across EU countries into a unified data structure.
For startups: Even affordable
template websites include essential markup — the minimum required for correct indexing from day one.
Validation: Every implementation is tested via Google Rich Results Test to ensure proper rendering.
In the era of AI, great content is not enough. Search engines must understand your business as clearly as your audience does. Proper structured data is an investment in the technical reliability of your marketing.
