360º Marketing helps company/brand positioning in a global point of view. It is a strategy that promotes regulating actions from different sectors to obtain a positive outlook. Using SEO or SEM strategies would be an example of 360º Marketing. The use of different channels and media is also 360º Marketing.
On the other hand, I would say that 6º Marketing consists of a closer approach to marketing, focusing on P2P – therefore, being more specific to the user. Which is something that is very present nowadays. If 360º Marketing is at a global level, I feel like 6º Marketing circles a specific user, leaving completely aside Mass Marketing and centring on micro-segmentation.
