Frequently Asked Questions

What is structured data and how does it help SEO?

Structured data is markup added to your HTML that helps search engines understand the content and context of your pages. It uses standardized vocabularies like Schema.org to describe entities such as products, articles, events, and organizations. Properly implemented structured data can earn rich snippets in search results, increasing visibility and click-through rates.

What is the difference between JSON-LD, Microdata, and RDFa?

JSON-LD is a JavaScript-based format that is added as a script block in your HTML head or body and is Google's recommended approach. Microdata embeds schema attributes directly into existing HTML elements. RDFa uses HTML attributes from the Resource Description Framework. JSON-LD is generally the easiest to implement and maintain since it is separate from your page markup.

Which types of structured data should I add to my website?

Start with Organization or LocalBusiness schema on your homepage, Article or BlogPosting for content pages, and Product schema for e-commerce listings. BreadcrumbList markup helps search engines understand your site hierarchy. FAQ and HowTo schemas can also earn enhanced search result appearances for instructional content.
