Is it worth it to pay Kim Kardashian $10,000 to tweet about your product?
Eric Barker stashed this in Marketing
It's about price-performance: "Even though the Kim Kardashians of the world were indeed more influential than average, they were so much more expensive that they did not provide the best value for the money."
The best strategy is portfolio diversification: lots of average people with above average influence, rather than a celebrity.
Basically, find just as hot women are are willing to do it for less.
