You can determine this with the help of a local marketing specialist or someone with in-depth knowledge of the local market. Standardizing the content is usually insufficient and broader and local issues must be taken into account, such as the content topics that are chosen, platforms that are used, audience digital consumer behaviors in that country, etc.
