Content marketing is a form of marketing focused on creating, publishing and distributing content for a targeted audience online.  It is often used by businesses in order to:
- Attract attention and generate leads
- Expand their customer base
- Generate or Increase online sales
- Increase brand awareness or credibility
- Engage an online community of users
Content marketing means attracting and transforming prospects into by creating and sharing valuable free content. The purpose of content marketing is to help companies create sustainable brand loyalty and provide valuable information to consumers, as well as create willingness to purchase products from the company in the future. This relatively new form of marketing usually does not involve direct sales. Instead, it builds trust and rapport with the audience.
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."  For content marketing, continuous delivery of large amounts of content is required, preferably within a content marketing strategy. 
When businesses pursue content marketing, the main focus should be the needs of the prospect or customer. Once a business has identified the customer's need, information can be presented in a variety of formats, including news, video, white papers , e-books , infographics , email newsletters, case studies, podcasts , how-to guides, question and answer articles, photos, blogs , etc.   Most of these formats belong to the digital channel.
Digital content marketing is a management process that uses digital products through different electronic channels to identify, forecast and satisfy the content requirements of a particular audience. It must be consistently updated and added to in order to influence the behaviour of customers.
Traditional marketers have long used content to disseminate information about a brand and build a brand's reputation . Business owners started to apply content marketing techniques in the late 19th century due to the technological advances in transportation and communication. They also wanted to build connections with their customers.  For example:
- In 1732, Benjamin Franklin issued the Poor Richard’s Almanack. Franklin wanted to promote his printing business. 
- In 1888, Johnson & Johnson introduced a publication called “Modern Methods of Antiseptic Wound Treatment” that was targeted to doctors that used bandages. They also released two publications that contained tips for the medical community. 
- In 1895, John Deere launched the magazine The Furrow , providing information to farmers on how to become more profitable. The magazine, considered the first custom publication , is still in circulation, reaching 1.5 million readers in 40 countries in 12 different languages. 
- In 1900, Michelin developed the Michelin Guide , offering drivers information on auto maintenance, accommodations, and other travel tips. 35,000 copies were distributed for free in this first edition. 
- In 1904, Jell-O salesmen went door-to-door, distributing their cookbook for free. Touting the dessert as a versatile food, the company saw its sales rise to over $1 million by 1906. 
- In 1933, Procter & Gamble started to broadcast a radio serial drama sponsored by their Oxydol soap powder. The owners wanted to build brand loyalty by aiming to adult women. They could intermix their marketing messages into the serial drama. The term soap opera was born in this year, and they marked a precedent for native ads. Engagement with the audience was a key element with the creation of this content. 
Between the 1940s and 1950s, TV was in their golden age, and advertising took over the media. Companies focused on sales rather than connecting with the public. There were few ventures into content marketing, and no very prominent campaigns.
During the baby boom era, Kellogg’s began selling sugary cereal to children. With this change in business model came sociable animal mascots, lively animated commercials and the back of the cereal box as a form of targeted content marketing. Infographics were born in this era. This represented a new approach to make a brand memorable with the audience. 
In the 1990s, everything changed for marketers. The arrival of computers and the Internet made websites and blogs flourish, and corporations found content marketing opportunities through email.
E-commerce adaptations and digital distribution became the foundation of marketing strategy.
Internet also helped content marketing become a mainstream form of marketing. Traditional media such as newspapers, magazines, radio and TV started to lose their power in the marketplace. Companies started to promote and sell their products digitally. 
The phrase "content marketing" was used as early as 1996,  when John F. Oppedahl led a roundtable for journalists at the American Society for Newspaper Editors.
- In 1998, Jerrell Jimerson held the title of "director of online and content marketing" at Netscape. 
- In 1999, author Jeff Cannon wrote,“In content marketing, content is created to provide consumers with the information they seek.” 
By the late 2000s, when social networks such as Facebook, Twitter, YouTube were born, online content marketing was accessible, shareable and on-demand anytime worldwide. 
By 2014, Forbes Magazine's website had written about the seven most popular ways companies use content marketing.  In it, the columnist points out that by 2013, use of content marketing had jumped across corporations from 60% a year or so before, to 93%  as part of their overall marketing strategy. Despite the fact that 70% of organizations are creating more content, only 21% of marketers think they are successful at tracking return on investment . 
Today, content marketing has become a powerful model for marketers. Storytelling is part of it, and they must convey the companies’ messages or goal to their desired audience without pushing them to just buy the product or service.
The rise of content marketing has turned traditional businesses into media publishing companies.
- Red Bull , which sells a high-energy beverage, has published YouTube videos, hosted experiences, and sponsored events around extreme sports and activities like mountain biking, BMX, motocross, snowboarding, skateboarding, cliff-diving, freestyle motocross, and Formula 1 racing. Red Bull Media House is a unit of Red Bull that "produces full-length feature films for cinema and downstream channels (DVD, VOD, TV)."  The Red Bulletin is an international monthly magazine Red Bull publishes with a focus on men's sports, culture, and lifestyle.
- The personal finance site Mint.com used content marketing, specifically their personal finance blog MintLife, to build an audience for a product they planned to sell. According to entrepreneur Sachin Rekhi, Mint.com concentrated on building the audience for MintLife "independent of the eventual Mint.com product."  Content on the blog included how to guides on paying for college, saving for a house, and getting out of debt. Other popular content included in-depth interview and a series of financial disasters called "Trainwreck Tuesdays." Popularity of the site surged as did demand for the product. "Mint grew quickly enough to sell to Intuit for $170 million after three years in business. By 2013, the tool reached 10 million users, many of whom trusted Mint to handle their sensitive banking information because of the blog’s smart, helpful content." 
The rise of content marketing has also accelerated the growth of online platforms, such as YouTube, Yelp, LinkedIn, Tumblr, Pinterest, and more.
- YouTube, a subsidiary of Google, is an online video platform driving (and benefiting from) the surge to content marketing.  As of 2016, YouTube had over 1 billion users, representing 1/3 of all internet users and reaching more 18-34 yr olds than any cable provider in the U.S. 
- Yelp, an online business directory, has seen 30% year over growth in the number of reviews, ending the second quarter of 2016 with 108 million reviews for over 3 million businesses. 
Businesses actively curate their content on these platforms with hopes to expand their reach to new audiences.
Metrics to determine the success of a content marketing are often tied to the original goals of the campaign.
For example, for each of these goals, a content marketer may measure different engagement and conversion metrics:
Brand awareness and visibility
Businesses focused on expanding their reach to more customers will want to pay attention to the increase in volume of visitors, as well as the quality of those interactions. Traditional measures of volume include number of visitors to a page and number of emails collected, while time spent on page and click-through to other pages/ photos are good indicators for engagement.
- Number of visitors to a page
- Time spent on the page
- Click-through across pages/ photos
- Number of emails collected
Brand health metrics
Businesses want to measure the impact that their messages have on consumers. Brand health refers to the positive or negative feedback that a company gets. It also measures how important a brand is for consumers. With this companies want to find out if brand reputation influences their customers to make a purchase.
Measures in this part comprise
- Share of voice (SOV) is the number of times a brand has been talked versus its competitors (conversations). Outside the digital world, SOV stands for the space and frequency a brand advertisement is placed on traditional media.
- Sentiment is when the brand has positive, negative or neutral feedback.
- Brand Influence refers to the number of times a post, comment or tweet is shared on different platforms. 
Diversified user base
For businesses hoping to reach not only more - but also new - types of customers online, they should pay attention to the demographics of new visitors, as evidenced by cookies that can be installed, different sources of traffic, different online behaviors, and/or different buying habits of online visitors.
- Demographics of visitors
- Sources of traffic (i.e., SEO, social media, referral, direct)
- Differences in buying patterns and user-behavior of visitors
Businesses focused on increasing sales through content marketing should look at traditional e-commerce metrics including click-through-rate from a product-page to check-out and completion rates at the check-out. Altogether, these form a conversion funnel. Moreover, to better understand customers' buying habits, they should look at other engagement metrics like time spent per page, number of product-page visits per user, and re-engagement.
- Conversion through the sales process (the process from sign-up to check-out), including click-through-rates at each stage of the conversion funnel
- Time spent on the page
- Re-engagement (i.e., % of returning visitors)
- Click-through across product pages

- Trend spotting refers to the latest consumers' comments about a brand, product or service that must be targeted. Some tools can be provided by Google Trends, Trendsmap (Twitter) and other sites that report what is in everybody's mouths worldwide.
Digital content marketing
Digital content marketing, which is a management process, uses digital products through different electronic channels to identify, forecast and satisfy the necessary of customers.  It must be consistently maintained to preserve or change the behavior of customers.
- On March 6, 2012, Dollar Shave Club launched their online video campaign. In the first 48 hours of their video debuting on YouTube they had over 12,000 people signing up for the service. The video cost just $4500 to make and as of November 2015 has had more than 21 million views. The video was considered as one of the best viral marketing campaigns  of 2012 and won "Best Out-of-Nowhere Video Campaign" at the 2012 AdAge Viral Video Awards.
- The Big Word Project , launched in 2008, aimed to redefine the Oxford English Dictionary by allowing people to submit their website as the definition of their chosen word. The project, created to fund two Masters students' educations, attracted the attention of bloggers worldwide, and was featured on Daring Fireball and Wired Magazine . 
- In mid 2016, an Indian tea company (TE-A-ME) has delivered 6,000 tea bags  to Donald Trump and launched a video content on YouTube  and Facebook.  The video campaign became an award winning content marketing and received various awards including most creative PR stunt  in Southeast Asia after receiving 52000+ video shares, 3.1M video view in first 72 hour and hundreds of publication mentions (including Mashable , Quartz ,  Indian Express ,  Buzzfeed  ) across 80+ countries.
Way of digital content marketing
Combination of the supply chain and the users' experience
The supply chain of digital content marketing mainly consists of commercial stakeholders and end-user stakeholders which represent content providers and distributors and customers separately.  In this process, distributors manage the interface between the publisher and the consumer, then distributors could identify the content that consumers need through external channels and implement marketing strategies. For instance, Library and document supply agencies as intermediaries can deliver the digital content of e-books, and e-journal articles to the users according to their search results through the electronic channels. Another example is when consumers pay for the acquisition of some MP3 downloads, search engines can be used to identify different music providers and smart agents can be used by consumers to search for multiple music provider sites. In a word, the digital content marketing process needs to be conducted at the business level and service experience level because when consumers are accessing digital content, their own experience depends on the complex network of relationships in the content marketing channels such as websites and videos. The consumers interact directly with distributors in the big supply chain through various digital products which have an important role in meeting the requirements of the consumers. The design and user experience of these channels directly decides the success of digital content marketing. 
Interaction with the consumer through electronic service
Electronic services refer to interactive network services.  In the electronic service, the interaction between the customer and the organizations mainly through the network technology, such as using E-mail, telephone, online chat windows for communication. Electronic services are different from traditional services and they are not affected by distance restrictions and opening hours. Digital content marketing through electronic service is usually served together with other channels to achieve marketing purposes including face-to-face, postal, and other remote services. Information companies provide different messages and documents to customers who use multiple search engines on different sites and set up access rights for business groups. These are some channels of digital content marketing.
