Structured data
Structured data refers to information that is arranged in a fixed schema. Among other things, this scheme enables search engines to clearly interpret the data. Typical examples of this are databases in which every piece of information has a fixed place and a clear meaning.
Differentiation from unstructured data
| Features | Structured data | Unstructured data |
| Format | Fixed scheme | No fixed scheme |
| Processing | Simple and efficient | Complex and time-consuming |
| Example | Databases, Excel tables | Emails, videos, text documents |
Due to their structured nature, structured data offers immense advantages in data analysis and information processing. They are the basis for the efficient use of data in various technology areas.
Types of structured data
Structured data can be available in different formats, each with specific use cases and benefits. Here are the most important species:
Meta tags
Meta tags are snippets of text that describe information about the content of a website for search engines. They play a key role in search engine optimization (SEO).
XML
The Extensible Markup Language (XML) is a flexible text format for structuring digital data. XML is often used for data exchange between different systems and platforms.
RSS feeds
RSS feeds allow users to receive regular updates of website content in a standardized format. They are particularly useful for following news and blog posts.
Microformats
Microformats are small HTML patterns that embed information about people, places, events and more in websites. They make it easier for search engines to understand and index website content.
Rich Snippets
Rich snippets are enhanced search results that display additional information such as star ratings, prices and authors. They are based on structured data and improve the visibility and click-through rate of websites in the search results.
