Go back and read the content marketing definition one more time, but this time remove the relevant and valuable. That’s the difference between content marketing and the other informational garbage you get from companies trying to sell you “stuff.” Companies send us information all the time – it’s just that most of the time it’s not very relevant or valuable (can you say spam?). That’s what makes content marketing so intriguing in today’s environment of thousands of marketing messages per person per day.
Unlike other forms of online marketing, content marketing relies on anticipating and meeting an existing customer need for information, as opposed to creating demand for a new need. As James O'Brien of Contently wrote on Mashable, "The idea central to content marketing is that a brand must give something valuable to get something valuable in return. Instead of the commercial, be the show. Instead of the banner ad, be the feature story."[3] Content marketing requires continuous delivery of large amounts of content, preferably within a content marketing strategy.[4]
In order for advertising copy to be successful, it must work well with the visual portion of the campaign. Copywriters need a working knowledge of the product, including its strengths and weaknesses, in order to most effectively write copy for a campaign. This also includes using knowledge of consumer behavior and market segmentation to properly target the advertising copy to a specific audience.
You write a blog post about your infographic generator, and included a link to the tool in the post so people can try it for themselves. Let's say the visitor-to-lead conversion rate is the same on this blog post as it was in your PPC campaign -- 2%. That means if 100 people read that blog post in your first month, you'd get two leads from it. But your work is done now. And over time, that one blog post you wrote years ago will continue to generate leads over, and over, and over, every single month. And not just that blog post -- every blog post you write will do the same.

While it's true Google can do a lot of the distribution work for you, it hinges on making smart decisions with your content strategy. In other words, Google might distribute the content you create, but it might distribute it onto page 32. Your job is to make sure as much content as possible appears as high up on page one as possible. This means your writers should be working closely with your SEO specialist to determine what keywords to go after -- ideally a combination of long tail terms and head terms, at an appropriate level of competitiveness given your domain authority and how aggressively you can go after the terms. Of course, that content should also be optimized for on-page SEO to improve its chances of ranking highly. 
The situation presented in this ad is realistic and something I’ve thought of before. It shows that Citi understands that wealth means different things for different people. It displays a sense of humor without being too self-aware. This ad appeals to your average middle-class citizen without alienating any other party. It benefits from being oddly specific because it makes it that much more relatable, especially as the price of a movie ticket continues to rise.
