Assess Their Knowledge of the Local Market (Kolkata)

As a startup, your initial market may be the local market of Kolkata, so ensure that the organisation you are focusing on has a good grasp of knowledge and understanding of the local market. It is good if the online marketing company in Kolkata to have international and pan-India based market knowledge. But if they lack the knowledge of the local market, then it can be a challenge for you too.

Having the knowledge of the local market means they understand the behaviour of the local audience. If you have both a local and an international audience, you would want a local marketing agency so that it can utilize the local audience behaviour as well as of the international market to make your business visible to both.  

Local SEO strategies can be set, and the cultural preferences can be better understood by the company if they are well aware of the local market. So, based on your own target audience category, ensure your hired digital marketing services in Kolkata have the local market knowledge.
