Sites for mobile devices
Search engines are improving search results for mobile devices such as smartphones and tablets. Mobile users are most likely to view a site with adaptive design, dynamic page layout, a mobile version of the site, or a Turbo page.
General guidelines
The recommendations for webmasters below are relevant for all approaches to site adaptation.
- Resources should be accessible for the Yandex indexing robot: Mozilla/5.0 (iPhone; CPU iPhone OS 8_1 like Mac OS X) AppleWebKit/600.1.4 (KHTML, like Gecko) Version/8.0 Mobile/12B411 Safari/600.1.4 (compatible; YandexBot/3.0;+http://yandex.com/bots). The robots.txt file must allow scanning CSS and Javascript that are responsible for displaying the site on mobile devices. Otherwise, the site pages might be displayed incorrectly in the search results.
- Site pages must respond to the server with the 200 OK HTTP code. You can check the server response in Yandex.Webmaster.
Don't use Flash, Silverlight, or Applet technologies on pages that are intended for mobile users. These technologies aren't necessarily supported on mobile devices.
Tip. For example, users can't view an interactive section of the site or videos implemented using Flash. We recommend using HTML5 to integrate content, or eliminating heavy and complex interactive elements.- Make your site's content maximally visible on a mobile device screen.
- The site content should fit on the screen horizontally.
- The text size in pixels should allow the entire text to be read comfortably on a mobile device screen.

How do I check my site's mobile pages?
- Choose the site with the page you need to check from the list.
- Enter the page URL in the field. By default, the home page of the site is specified.

The check takes a few minutes.

You can optimize the content of the site pages for mobile search. For example, you can leave only the content that will be useful for the users of mobile devices. At the same time, the mobile pages' content shouldn't be dramatically different from the content of the main version.
Yandex treats the main version and the mobile version of the site as separate sites and indexes them separately from each other.
To help the robot identify the mobile version correctly, specify the URLs of the mobile pages on the corresponding pages of the main site. For example, you can use the link
element:
<link rel="alternate" media="only screen and (max-width: 640px)" href="http://m.example.com/page.html"/>
You can redirect the user from the main site to the mobile version, depending on the user agent of the device from which the user browses the site.
You can add a mobile version of the site to Yandex.Webmaster to track the page indexing statistics.
If the mobile version of the site is located in the main site's directory, the Yandex indexing robot can't index it correctly and recognize the site as mobile compatible. Use adaptive design or dynamic layout.
For sites with adaptive design, use the <meta name="viewport" content="width=device-width, initial-scale=1">
meta tag to specify the viewport. For more information, see the Using HTML tags section.
This may happen if the content of the mobile and main versions is identical. This doesn't affect the site's recognition as mobile compatible and the display of the mobile version in mobile search.
