Don't get excited by what's new, get excited by what works
Something I've been reflecting on recently is it's better to get excited about marketing strategies that have been proven to work, rather than strategies that are brand new.
For example, if I'm analysing the success of Fab.com, I shouldn't get too excited and want to adopt parts of their live news feed the week it launches, I should look at what it is they've done that's proven to work by making their business so successful to date.
In their case it's email marketing that, until recently, was their largest traffic driver.
It's tempting to get excited by brand new marketing strategies, and in some cases that can work, but until you've got the basics right, like SEO, SEM, email marketing and social media, you'll likely get a better ROI on your marketing spend focusing on the tried and true approaches to marketing.
