How Yandex indexes sites
A site on search results page


Schema.org is a standard for semantic markups of online data that was published by Google, Bing, and Yahoo's search services in the summer of 2011.

The principle of semantic markups is to make the internet more understandable and structured, while also making it easier for search engines and special programs to extract and process key information and display it in search results.

You can markup documents using special attributes that are entered directly into HTML code. You do not need to create any separate export files.

Why micro-markups are useful

You can use semantic markups to improve how your website's snippets looks in search results.

Compare the search result snippets for a page from a website participating in Yandex.Dictionary's partner program, one version semantically marked and the other not.

The standard provides a set of classes describing a variety of entities and their properties. There are already several hundred of them. The standard is constantly being improved, new properties are being added, and existing ones are being fine-tuned.

You can check out a description of the standard in the documentation section of Schema.org's official website.

Basic markup principles

There are two steps to every Schema.org markup:

  1. First you place division or section tags around a given type of data and enter your markup attributes:

    <div itemscope itemtype="http://schema.org/Organization" >
  2. Then you enter the appropriate values for each markup attribute:

    <span itemprop="streetAddress">16 Lva Tolstovo</span>
