Like music notes, the number of ways those three elements can play out is nearly endless. There are so many types of marketing born from the three basic components – definitely more than can fit in one listicle.
But if we had to pick the 11 greatest hits of our time, this is what they would be:
Let's take a deeper dive into what each is all about.
A few terms to be familiar with first:
OK, for real this time:
1. Advertising
Advertising is what most people think about when they think about marketing: a TV commercial, a YouTube ad, a print ad in a magazine, an ad during a podcast, ads you might see on the subway, billboards on the highway, digital banner ads on the side of a news article and any other campaign where you paid someone to publish, print, display or air your ad.
Think of advertising as an imposition on your attention.
Ads kind of follow you around and actively try to get you to notice them. That's why advertising is often called interruption marketing. To avoid these interruptions, you might find yourself taking evasive measures – like muting the TV or changing channels during the commercial break, hitting the fast-forward 30 seconds button on a podcast and using an adblocker while browsing the web.
So why advertise?
Because it can be great for brand awareness, and it can be useful to target an audience that has already shown interest in your brand (that's why, for instance, you might see banner ads for discount boots on websites after you've been shopping for them).
The downside of advertising is that you're sure to be paying money every time you get your content in front of an audience. In this sense, it's less cost-effective over the course of a campaign than a well-executed organic content marketing effort.
2. Content marketing

The internet – and specifically a search engine.
That's why content marketing and search engine optimization (SEO) are often conflated.
Technically, they're a little different.
Content marketing is the development of original high-quality content that a target audience will find useful, and that isn't overly promotional. This includes blog posts, podcasts, how-to-videos, original research, infographics, eBooks, white papers, free online tools and other non-interruptive marketing efforts.
SEO is about making this content more discoverable on search engines: It improves the odds that your target audience will discover your webpages when they search for questions and information that your brand has answered through digital content.
Content marketing and SEO both fall under the umbrella of digital marketing, which is why you may hear them imprecisely referred to as online marketing/internet marketing.

3. Search engine marketing

The basic idea is that businesses pay Google a certain dollar amount each time someone clicks on a paid search result. Those paid search results are clearly labeled as ads (see the example above), which means that they tend to be clicked on less than organic results (results that do not say "Ad" next to them).
The thing to remember about SEM is that you need content on the other end of every banner ad and paid search result.
At a high level, SEM is just one type of digital advertising. Other ways to advertise on the web include:
4. Social media marketingSocial media marketing is exactly what it sounds like: the use of social media platforms to distribute unpaid content, like in the example above, or paid content, like this paid ad on Facebook:


They typically use action language, like:



The goal is to get a user to take an action, like providing an email in exchange for reading an eBook or a white paper.
That action should lead to deeper engagement with your brand. By capturing an email, for instance, you put that lead on a track for email marketing efforts.
In this sense, CTA marketing is a critical component of inbound marketing strategies where the goal is to lead users deeper into the sales funnel, and prime the pump for a conversation.
6. Direct marketing

Technically, direct marketing falls under the umbrella of outbound marketing. Tracy, for instance, might be a regular reader of the Brafton newsletter, but she didn't log onto her email that morning expecting to receive a personalized analysis of her site's domain authority followed by a request for a call. It may be a little more, say, direct than she's used to.
Nevertheless, direct marketing has its place in inbound marketing. It's possible, for instance, that Tracy downloaded, say, an eBook we wrote about building domain authority. In that case, she's an inbound lead that has been primed, making her an ideal prospect for a more direct approach.
Other examples of direct marketing are in the mail – like those "you're pre-approved" credit card offers, and cold calling a list of leads.
In a vacuum, direct marketing comes across as aggressive and spammy. But when well-timed as part of a bigger marketing plan, it can be the push that gets a prospect to become a customer.
7. Account-based marketing

It's incredibly unconventional, but it supposedly got the attention of T-Mobile's CEO.
The gamble with account-based marketing is that it might not work. And if the campaign is too narrow in scope – say, like a comic book about T-Mobile – it runs the risk of being a wasted investment if the target ultimately gets away.
That's why, when creating ABM campaigns, it's always better to base them around personas as opposed to one specific customer if at all possible. You can reuse that content if it isn't overly specific.
8. Guerrilla marketing

It can be a clever, attention-grabbing ploy like the KitKat bench or this Frontline ad:

Guerrilla marketing is not to be confused with experiential marketing. They're similar in that they tend to be highly creative and attention-grabbing. However, the latter is a little more experience-oriented. An example would be Refinery 29's 29 rooms:
Guerrilla (and experiential) marketing doesn't have to be super expensive. However, it does require resourcefulness, and cautiousness not to end up on the wrong side of the law (especially if you plan to paint on things that don't technically belong to you).
Guerrilla marketing inspires people to take to social media and gets people talking about the crazy-cool thing your brand did.
9. Marketing automation

A marketing automation platform can improve segmentation (creating lists of recipients) by programming certain messages to send out to certain leads at a very particular time and day.
Marketing automation was made for email marketing and digital advertising.
The idea is that certain content is sent to or displayed for certain users based on their content consumption habits. Said habits are recorded within a tool like Pardot or Marketo. Ideally, you'll know exactly what post the email contact was reading when they first gave you their information, and what, if any, marketing collateral they've downloaded since then.
Email drip campaigns are good examples of marketing automation. The contents of each message are based entirely on the recipient's interaction with the previous message. This ensures that the next message a recipient sees is the message that is most likely to get them engaging with your brand.
If you have any aspirations of launching an email marketing campaign and improving the precision of your interactions with leads as you go deeper into the sales funnel, you're going to need marketing automation resources.
10. Public relations

Public relations isn't reserved just for the KFCs of the world, though.
Small businesses also need PR. For instance, how they communicate with their customers and their business partners following a data breach is important to their recovery as an organization.
And PR doesn't necessarily have to follow a disaster. Highlighting your charitable exploits in a blog post is an opportunity to earn some positive publicity. So is attending local events in the community and publishing a press release when your brand is recognized by an industry magazine.
Anything you can do (within your means) to earn positive media attention will ultimately help your brand.
11. Event marketing

Maybe it's an event you're hosting, like an industry conference, a lunch-and-learn or even a live webinar. When done right, a really well-executed event is its own form of marketing. But you need to actually have an audience at that event in the first place.
Start by creating a landing page for that event, and promoting it on your blog, through social media channels and via email.
Also consider live-Tweeting or posting on other social channels. Once it's over, create a blog post (or multiple posts) summarizing some of the highlights.
The same applies if you're participating in someone else's event or partaking in a well-known industry conference, and want to make sure people know you'll be there.
You don't necessarily have to be giving a keynote address, either. Even if you're just going to learn and network, share your experiences with other people on your blog and through social media (like we did when we went to MozCon and Content Marketing World). It also helps to have something to hand out during the event. These could be limited-time promos and coupons, company swag, a brochure or – at the very least – a business card.
Did we snub your favorite type of marketing? It's possible. Entire books have been written about marketing strategies.
But this was hopefully a good primer as you wade deeper into the world of marketing.
