1. Make a list of top 20 websites that get hits from the locations you want to target to!
2. Always be aware of the fact that the local language of communication is very important.
For example:You can not sell something in China if you hardly know Chinese (Mandarin). And also, English is not going to be that effective there. Bottom-line is that you will have to use Google Translate more often than not - to carry out the digital marketing / promotion activities.
3. Update your website with multi-language feature! People speaking different language can come to your website and read the content in their language. It is always advisable to have the website in atleast THREE languages: English, Spanish, and Arabic. Majority of the world population gets covered in these 3 languages.
