Why do you need contextual advertising?
Contextual advertising is an opportunity to appear in the right time and place. This will let you be "in the moment" when a user needs your product or may be interested in your company's services.
Contextual advertising will help build communication between the consumer and your brand. In the long term, the brand becomes recognizable and gains an audience of loyal customers.
Contextual advertising will help you declare your presence on the market, present a new product or service.
