This will help you to reach targeted audience regionally or globally. Once you do all of these steps you would find better keywords rankings, increased impressions to your website.
All you need is to make some changes to your website code and your Google's search console account. I am going to define the steps below.
HTML's Language Declaration:
Declare the language used on your page in HTML Tag. To do this, go to your page's source code and check the html tag at the top. <html> and find this line lang="en" within tag. If not then you have to define in your code the lang attribute where set the language and region preference. for ex:
"en" en is the English and US is the Region
