Hi, Habr! Google search is evolving, and related tools are evolving with it. In the near future, the user agent of Googlebot, which is responsible for the “mobile” direction of search, will be updated. Currently, useragent looks like this:
Current useragentMozilla / 5.0 (iPhone; CPU iPhone OS 8_3 like Mac OS X) AppleWebKit / 600.1.4 (KHTML, like Gecko) Version / 8.0 Mobile / 12F70 Safari / 600.1.4 (compatible; Googlebot / 2.1; +
http: // www .google.com / bot.html )
From April 18, 2016, the new Google Smartphone user agent will be used:
Mozilla / 5.0 (Linux; Android 6.0.1; Nexus 5X Build / MMB29P) AppleWebKit / 537.36 (KHTML, like Gecko) Chrome / 41.0.2272.96 Mobile Safari / 537.36 (compatible; Googlebot / 2.1; + http://www.google .com / bot.html )
The reason for such changes - the new features of the search robot. Every time, our robot receives a meaningful update and the ability to handle pages that use the most current technology. In this case, the new format of the string says that technically Googlebot is now closer to the Chrome browser, and not Safari.
Web Developer Tools
Understanding how our website sees your search robot is easier than you think. Especially for this tool is designed to "see how Googlebot." In addition, if you want your site to be easily viewed in different browsers, but do not know where to start, we recommend using the tool to
check support functions and adhere to the principles of progressive improvement. Well, this is if we discard the obvious advice of the form "use the approved standards", "avoid experimental features" and "do not procreate the essence beyond the necessary."

According to our forecasts, changing the user agent string will not affect the processing of the vast majority of sites, however, problems may arise if the site checks this string.
First, according to our beliefs, the content for the search engine should not differ from the content that the user sees. Therefore, checking and changing content depending on useragent in order to mislead the search engine is regarded by Googlebot as one of the forms of
disguise . The site should take Googlebot as a normal browser.
If you think that there may be errors on your site, check it with
this tool * (with updated user agent string) in Search Console or change the string in your browser’s developer tools (for example, using
mobile device emulation mode in Chrome browser) . If you have any questions, ask them in the
help forum for webmasters ,
or here in the comments
* - Sign-in is required with a Google Webmaster account and sites attached to it.
Secondly, almost a year ago we talked about a major search engine update that affected many aspects of mobile versions of sites. If you missed that announcement, you can read about it
in our Habrablog . We hope that over the year all webmasters have become preoccupied with supporting the mobile version, if it is relevant on their sites. Well, if you did not have time or could not do everything that you wanted - many tips, recommendations and useful links in that material are still relevant.
