Business, as the cliché goes, is not just about what you know, it’s about who you know.

And in this ultra-connected world, where social media exponents like Twitter and LinkedIn make interaction easier than ever, forging relationships with the right people is integral.

But how connected are you to the people that matter? Those clients who oversee the marketing budgets of the biggest and brightest brands in the UK?

To help people find out, we’ve come up with the Engine Power Index, a clever little tool that measures how connected each person is within the industry.

So even if you weren’t featured in Marketing’s Power 100, which launched today, make sure you visit our Power Index site here to get your very own rating.

It may just make for a bit of fun. It may be a nice catalyst to help you wind-up/get one over on your colleagues. Or it may be the first step on the road to seeing a whole host of new names break through to feature when Marketing’s Power 100 appears once again in 2013.
