Bounce rate from other country for India based site, so my question is to add multilingual tag to sites helps to reduce bounce rate? Also I want more business from outside India so what to do for it.
Yes, it is one of the technique to reduce the bounce rate of a web page, if you won't understand the language of the site then you can change the language and can easily read the content on it.
If you provide the content in user language, then it will be easy for him to understand & spend some time on the website, which will ultimately reduce the bounce rate.
