Translated results

Google Search strives to make information accessible and useful to all users. To help address content gaps when a user searches in their local language, sometimes Google may translate the title link and snippet of a search result for results that aren't in the language of the search query. A translated result is a Google Search feature that enables users to view results from other languages in their language, and can help publishers reach a larger audience.
Currently, translated results are available for English results to the following languages: Indonesian, Hindi, Kannada, Malayalam, Tamil, Telugu. It's available on mobile devices with any browser that supports Google Search.
If the user clicks the translated title link, all further user interaction with the page is through Google Translate, which will automatically translate any links followed. By expanding the result, users can view the original title link and snippet, and access the entire page in the original language.

Google doesn't host any translated pages. Opening a page through a translated result is no different than opening any other URL in Google Translate. This means that Javascript on the page is usually supported, as well as embedded images and other page features.
Monitor performance in Search Console
To monitor clicks and impressions for translated results, you can use the Search Appearance filter in the Performance report.
Opting in or out of translated results
This feature is applicable across all pages and results based on the user's language. You don't need to do anything to opt in.
Translated results are like other translation-related features in Google Search. To opt out of
all translation features in Google Search, use the
notranslate
rule,
which can be implemented as a meta
tag or an HTTP header:
<!-- opt out of translation features on all search engines that support this rule --> <meta name="robots" content="notranslate">
<!-- opt out of translation features on Google --> <meta name="googlebot" content="notranslate">
Alternatively, you can specify the rule as an HTTP response header:
HTTP/1.1 200 OK Date: Tue, 25 May 2010 21:42:43 GMT (...) X-Robots-Tag: notranslate (...)
