What is structured data?
Structured data is code in a specific format, written in a way that search engines understand. Search engines read the code and use it to display search results in a specific and richer way. You can easily place this code on your website. Imagine you have a website with many recipes. If structured data is added to a page with recipes, the results in the search engine may change. For the displayed content, it will be more "rich". This is why we call these results rich results or rich snippets. This is a rich result: 
in the search results, in addition to the title, URL, and description of the search result, you can also see how long it takes to make the absolute best lasagna. Also, you will see how many calories the lasagna contains. You need to add structured data to the page to get such a rich code snippet. There are all kinds of structured data. Structured data is always in code format. For example, there are structured data for books, reviews, movies, and products in online stores. In all cases, structured data will add more details to your code snippets in search results. Browse Google’s search library to see which rich results are supported by structured data. We must make a side note here. Unfortunately, even if you add structured data, Google doesn’t always create rich snippets of your pages. no promises. So all you can do is add it to your page and hope Google can pick it up! ## How do you deal with structured data?
Using structured data, you can "talk" to search engines. You can tell search engines which ingredients are in your recipe, you can tell them how long it takes to prepare, and you can tell them how many calories the dish contains. Google will be able to grasp all this information immediately and decide to display it in search results. Therefore, structured data is a tool that can be used to tell Google (in a way to understand what you are saying) detailed information about a page on your website. Google will then be able to use this information to create informative search results. The audience loves these rich clips! ## What is Schema.org?
The large search engine developed a project called Schema.org . On Schema.org, you can find all structured data tags supported by search engines. This makes Schema.org a lot of code. You can use Schema.org to find the markup you need for a particular page. For example, if you sell T-shirts on your website, you can display the colored T-shirts you sell and the size you provided in the code snippet. You should investigate Schema.org/Product and find out the possibilities. On Schema.org, you can copy the code examples. After copying, you must adjust the code to your specific preferences. 
Schema.org is a classification of code formats understood by large search engines. You will find examples of how the code looks. There are other forms of structured data. Examples are Open Graph (used by Facebook) and Twitter cards (used by Twitter). ## What is JSON-LD?
JSON-LD is one of the marks of Schema.org. This is just one way to write code. On Schema.org, you can also find other markups such as Microdata or RDFa. At Yoast, we recommend that you always use JSON-LD because it is not as easy to break your website as other markups. You can-relatively easily-use Google Tag Manager to add JSON-LD to your website. Other tags cannot achieve this. ## Why is structured data important for SEO?
Structured data is important for SEO because it makes it easier for Google and Baidu to understand the content of your web pages and websites. Google and Baidu need to find out what the page will show in search results. Using structured data is like talking to Google and Baidu, telling Google and Baidu what your website is. This will help your ranking. Most importantly, structured data will change the look of your code snippets (search results). It will show more information to your customers. More specific information. This will increase the likelihood that customers will click on the results. More clicks will eventually lead to higher rankings! We are seeing more and more structured data driven rich results pop up, so it is important to pay close attention to this. ## How to use structured data?
Using structured data sounds difficult, but everyone can do it-with proper training. You must get the correct code, you must adjust the code, and you need to use Google Tag Manager to place it on your website. ## No code master? Use plug-ins!
Many structured data tags can also be added to your website using plugins. For example, our local SEO optimization plugin uses structured data to display 1 location or multiple locations of the store. You don't need to write code to get rich code snippets, you just need to use our plug-in, fill in some details, and we will do it for you. There are more plug-ins to help you use structured data without worrying about any code! With Yoast SEO , there is a better and simpler way to add structured data using WordPress' new block editor: structured data content block.
