JSON-LD has become the standard format for adding structured data to business websites. It is clean, maintainable, and recommended by Google. Implementing it correctly can unlock rich search results that significantly improve your visibility and click-through rates.
Why JSON-LD Over Other Formats
Structured data can be implemented using three formats: JSON-LD, Microdata, and RDFa. Google explicitly recommends JSON-LD because it separates structured data from HTML content, making it easier to implement and maintain. It can be added without modifying existing HTML markup, and it is the most commonly used format by developers worldwide.
LocalBusiness Implementation
Every local business website should have LocalBusiness JSON-LD on the homepage and contact page. This includes business name, address, phone number, hours, service area, social profiles, and images. This structured data helps Google display accurate business information in search results and knowledge panels.
Service Schema
Service schema describes what your business offers. Each service page should include schema identifying the service type, description, provider, area served, and any relevant attributes. This helps search engines understand your offerings and match them to relevant queries.
FAQ Schema for Rich Results
FAQ schema is one of the most impactful schema types because it can generate expanded search listings showing your questions and answers. Add FAQPage schema to any page containing FAQ content. Each question-answer pair should match the visible content on the page exactly.
Validation and Monitoring
Always validate JSON-LD before deployment using Google Rich Results Test. After deployment, monitor the Coverage and Rich Results reports in Google Search Console for errors. Schema markup that contains errors is worse than no markup because it can confuse search engines about your content.
AppWT found this kind of problem on its own blog. On October 3, 2026, every post on appwt.com served two BreadcrumbList blocks, one from the site header and one from the post template. AppWT now passes each post's trail to the header so the page serves a single block, and it parses every block on every post to confirm none is broken.
Advanced Implementations
Beyond basics, consider implementing HowTo schema for instructional content, Article schema for blog posts, Product schema for e-commerce, Event schema for events, and VideoObject schema for video content. Each type creates opportunities for enhanced search result displays.

Frequently Asked Questions
What is JSON-LD?
JSON-LD stands for JavaScript Object Notation for Linked Data. It is a method of encoding structured data using JSON format that can be added to the HTML of your web pages. Google recommends JSON-LD as the preferred format for structured data because it is easy to implement and maintain.
Where do I put JSON-LD code on my website?
JSON-LD code is placed within script tags in the head or body section of your HTML pages. It does not affect the visual appearance of your page. You can include multiple JSON-LD blocks on a single page to describe different entities or data types.
How do I test if my structured data is working?
Use Google Rich Results Test to check if your structured data is valid and eligible for rich results. Use the Schema Markup Validator for general validation. After deployment, monitor the Rich Results report in Google Search Console for any errors or warnings.
