There's no "right" answer to this question -- a digital marketing strategy thrives on more than three things -- but certain answers show the candidate is up to date on how businesses attract and delight their customers today.
"A Facebook page," for instance, isn't a wrong answer, but it doesn't give you context around how a business would use this page in their marketing strategy. Here are a few sample answers to this interview question that are on the right track:
☛ A blog with calls to action (CTAs), landing pages for website visitors to download more content, and a defined social media strategy.
☛ An SEO strategy, website chat, and an analytics tool to track campaign performance.
☛ Buyer personas, a Marketing and Sales Service Level Agreement, and a customer success strategy.
