While a strategic shift is underway, a modern marketer's tactics also need to change.

According to Halligan, the first and most important tactic needed for that disruptive, strategic approach is to build an online presence. "If you're not online, you're an invisible business," Halligan said. "You're like a billboard in the desert: No one's driving by."

But merely having a website and engaging with a few inbound marketing tactics isn't enough, Halligan pointed out, citing companies that have low social media presence and blog only semi-regularly.

"That's a mistake a lot of companies make: They stick their toe in the water, but they don't go deep enough," said Halligan.

Halligan suggests that as CMOs, CEOs and business owners transition from older, outbound methodologies to new, inbound tactics, they need to constantly pit the two approaches against each other and measure the results of each.

"Measure, measure, measure, " said Halligan. One of the most important questions people should be asking is, "What is my cost to acquire a customer the old way versus the new way?" Blogging is another tactic that businesses can't ignore when crafting their new inbound marketing strategy. When asked if consumers today have blogging fatigue, Halligan disagreed.

"No, I don't think we do," Halligan said. "A good blog article is like a magnet to customers" because it answers their questions and is optimized for search engines.

But Halligan warned against blogging just for blogging's sake - without an overarching strategy, the tactic is worthless. "I think there needs to be a shift in blogging from quantity to quality," Halligan said. "Mediocre blogging is nearly useless today. You have to be a very good blogger with remarkable content or it's almost a waste of time." One final mistake Halligan noted that companies make with their inbound marketing strategy is not giving it enough time to achieve their desired results. "It takes time," Halligan pointed out.
