Digital Marketing Ecosystem - mapped

I have been thinking a lot recently about getting the different teams with some responsibility for digital activity to work together more closely. It's clear that the different activities - SEO, content, PR, social, display, PPC, market research and customer service, all impact on each other and can have positive feedbacks if planned correctly.  For example, a well-planned piece of content can boost organic search traffic your website, serve as a destination and 'reason to click' for display ads, convert visitors into leads, increase the relevance (reducing cost) for your paid search, drive shares and likes on social networks - resulting in 'free' traffic, and garner inbound links which result in further improved organic search rankings.

I was looking for some kind of diagram or map that would bring it all together and I came across this from Dave Fleet - brilliant and visionary thinking - though I found it a little complicated on the eye and hard to explain to internal stakeholders. So I had my own stab at my own version, and mapped onto it the types of activities each of the flows consists of, hopefully adding some value to Dave's original in the process.
