The most common mistake marketers make when designing and executing an inbound marketing strategy is attempting to do it all by themselves. Doing anything solo usually adds additional risk. Team efforts almost always prevail over one-man shows – just ask Lebron. Batman had Robin. Ben had Jerry. Lewis had Clark. And Lennon had McCartney. Heck, even when I was 12 years old, I was told to never go swimming in the lake without a “buddy.” So marketing needs to team up with sales to mitigate risk and increase the likelihood of success.
