What is structured data in SEO?

Structured data in SEO refers to a standardized format for providing information about a page and classifying the page content.

It’s a code in a specific format, written in such a way that search engines understand. This code tells search engines what your content is about — whether it’s a product, a review, an article, or a person. The most common format is JSON-LD.

Importance

  • Enhances visibility: It can lead to rich snippets in search results, making your page stand out.
  • Improves understanding: Helps search engines understand the content of your website better, potentially boosting your SEO performance.
  • Increases click-through rates: Features like ratings and prices can be shown directly in search results, making it more likely users will click on your site.

How it Works

When you add structured data to a webpage, you’re essentially labeling parts of the content so search engines can categorize it. For instance, if you run a recipe site, structured data can label ingredients, cooking time, and calories.

Implementation

1. Use a tool like Google’s Structured Data Markup Helper.
