As a marketing strategist, or anyone who is working towards marketing goals, your marketing mix should strategically ladder up to your objectives. Finely crafted marketing strategies should guide every touchpoint you have with your prospects and existing customers. For example, if a tactic effort you are considering doesn't fall under one of the strategies you’ve chosen, you shouldn’t do it.
Strategies are the how to help you achieve your objectives.
Okay, so how do you get there? A strategy should never be a guess, an assumption or just an idea you've brainstormed. Success as a marketer requires many things, but without data and proper marketing planning, you're really just planning to fail.
