Native advertising is a type of advertising, usually online but feasibly elsewhere, that matches the form and function of the platform upon which it appears.
In recent times, the customers you are trying to reach have gone blind to whatever ads you are putting on. Your ads just don't work anymore and google advertising is very expensive and highly competitive.
With Native advertising, things have changed. You really have nothing to worry about but to bring value to your customers and then turn them into long-lasting clients.
