When you spend $1 on marketing, how much profit do you get back? Because that's the ONLY thing that counts. Sorry if you don't like that answer but it's true.. Facebook 'likes', web hits and Google ranking might make your report look good. But you can't take them to the bank. If you don't agree with this, then I'm not your girl. I have many different skills, but they're all geared around one thing: increasing the return on your marketing investment. That's the only rational way to measure the effectiveness of a marketing consultant.
