Digital Marketing
Digital marketing and inbound marketing are easily confused, and for good reason. Digital marketing uses many of the same tools as inbound marketing—email and online content, to name a few. Both exist to capture the attention of prospects through the buyer’s journey and turn them into customers. But the 2 approaches take different views of the relationship between the tool and the goal.

Digital marketing considers how each individual tool can convert prospects. A brand's digital marketing strategy may use multiple platforms or focus all of its efforts on 1 platform.

Inbound marketing is a holistic concept. It considers the goal first, then looks at the available tools to determine which will effectively reach target customers, and then at which stage of the sales funnel that should happen.

The most important thing to remember about digital marketing and inbound marketing is that as a marketing professional, you don’t have to choose between the 2. In fact, they work best together. Inbound marketing provides structure and purpose for effective digital marketing to digital marketing efforts, making sure that each digital marketing channel works toward a goal.

Types of digital marketing
There are as many specializations within digital marketing as there are ways of interacting using digital media. Here are a few key examples.

Search engine optimization
Search engine optimization, or SEO, is technically a marketing tool rather than a form of marketing in itself. The Balance defines it as “the art and science of making web pages attractive to search engines.”

The "art and science" part of SEO is what’s most important. SEO is a science because it requires you to research and weigh different contributing factors to achieve the highest possible ranking. Today, the most important elements to consider when optimizing a web page include:

Quality of content
Level of user engagement
Mobile-friendliness
Number and quality of inbound links
The strategic use of these factors makes SEO a science, but the unpredictability involved makes it an art.

In SEO, there's no quantifiable rubric or consistent rule for ranking highly. Google changes its algorithm almost constantly, so it's impossible to make exact predictions. What you can do is closely monitor your page's performance and make adjustments accordingly.

Content marketing
SEO is a major factor in content marketing, a strategy based on the distribution of relevant and valuable content to a target audience.

As in any marketing strategy, the goal of content marketing is to attract leads that ultimately convert into customers. But it does so differently than traditional advertising. Instead of enticing prospects with potential value from a product or service, it offers value for free in the form of written material.

Content marketing matters, and there are plenty of stats to prove it:

84% of consumers expect companies to produce entertaining and helpful content experiences
62% of companies that have at least 5,000 employees produce content daily
92% of marketers believe that their company values content as an important asset
As effective as content marketing is, it can be tricky. Content marketing writers need to be able to rank highly in search engine results while also engaging people who will read the material, share it, and interact further with the brand. When the content is relevant, it can establish strong relationships throughout the pipeline.

Social media marketing
Social media marketing means driving traffic and brand awareness by engaging people in discussion online. The most popular platforms for social media marketing are Facebook, Twitter, and Instagram, with LinkedIn and YouTube not far behind.

Because social media marketing involves active audience participation, it has become a popular way of getting attention. It's the most popular content medium for B2C marketers at 96%, and it's gaining ground in the B2B sphere as well. According to the Content Marketing Institute, 61% of B2B content marketers increased their use of social media this year.

Social media marketing offers built-in engagement metrics, which are extremely useful in helping you to understand how well you're reaching your audience. You get to decide which types of interactions mean the most to you, whether that means the number of shares, comments, or total clicks to your website.

Direct purchase may not even be a goal of your social media marketing strategy. Many brands use social media marketing to start dialogues with audiences rather than encourage them to spend money right away. This is especially common in brands that target older audiences or offer products and services not appropriate for impulse buys. It all depends on your company's goals.

Pay-per-click marketing
Pay-per-click, or PPC, is posting an ad on a platform and paying every time someone clicks on it.

How and when people see your ad is a bit more complicated. When a spot is available on a search engine results page, also known as a SERP, the engine fills the spot with what is essentially an instant auction. An algorithm prioritizes each available ad based on a number of factors, including:

Ad quality
Keyword relevance
Landing page quality
Bid amount
Each PPC campaign has 1 or more target actions that viewers are meant to complete after clicking an ad. These actions are known as conversions, and they can be transactional or non-transactional. Making a purchase is a conversion, but so is a newsletter signup or a call made to your home office.

Whatever you choose as your target conversions, you can track them via your chosen platform to see how your campaign is doing.

Affiliate marketing
Affiliate marketing lets someone make money by promoting another person's business. You could be either the promoter or the business who works with the promoter, but the process is the same in either case.

It works using a revenue sharing model. If you're the affiliate, you get a commission every time someone purchases the item that you promote. If you're the merchant, you pay the affiliate for every sale they help you make.

Some affiliate marketers choose to review the products of just 1 company, perhaps on a blog or other third-party site. Others have relationships with multiple merchants.

Whether you want to be an affiliate or find one, the first step is to make a connection with the other party. You can use a platform designed to connect affiliates with retailers, or you can start or join a single-retailer program.

If you're a retailer and you choose to work directly with affiliates, there are many things you can do to make your program appealing to potential promoters. You'll need to provide those affiliates with the tools that they need to succeed. That includes incentives for great results as well as marketing support and pre-made materials.
