As a social media marketer I have found photography perhaps the best strategy in content creation. Social media has revolutionised the entire paradigm that is marketing. Success is totally content-driven - create engaging content or be damned to internet oblivion.
In studying metrics in my work in facebook marketing it is apparent that the rate of engagement with photographic content is significantly higher than it is for other forms of content, in fact many times higher. The numbers don't lie.
The salient thing is, people are inherently social creatures, so it follows that they like to click on images of people, especially people that they know or people in their extended social networks. The ability to connect with community has become more than ever a core concern for business. The best Social Media Marketing practitioners are those who understand the social dimension
and who can consistently generate content with 'personality'.
