One of the patterns I notice most when talking with business owners is that the word marketing means something different depending on who's using it. For some it's Instagram ads, for others it's the logo and the color palette, and for quite a few it's an expense they'll sort out "when there's time". And since what is marketing remains one of the most searched questions on Google in Peru and across the region, it's worth answering it properly: what it actually is, how it differs from advertising, and what it looks like in practice when it's done well.
What is marketing?
Marketing is the process of understanding what a group of people needs and organizing your product, your price, your channels and your communication so that those people choose you. The American Marketing Association defines it as the activity and processes for "creating, communicating, delivering, and exchanging offerings that have value". It sounds like a textbook, but the underlying idea is much simpler: knowing your customer so well that selling to them stops being a fight.
Peter Drucker, who wrote about management half a century before Instagram existed, summed it up by saying that the aim of marketing is to know the customer so well that the product practically sells itself.
My favorite example to make it concrete: the vendor at the local market who sets aside the good avocados for you because she knows you come every Saturday is doing marketing, even though she'd never call it that. She knows her customer, knows what they value, adjusts her offer and makes sure you come back. The campaigns, funnels and metrics that come later are scaled-up versions of that same logic.
Are marketing and advertising the same thing?
It's the most common confusion, so let's clear it up right away. Advertising is one tool inside marketing: you pay to appear in front of an audience. Marketing starts much earlier and ends much later. Deciding what to sell, at what price, through which channels and with what message are all marketing decisions, and advertising only enters at the very end of that chain.
The classic framework for organizing those decisions is the marketing mix with its 4 Ps: product, price, place and promotion. Advertising lives inside just one of those four. That's why, when a business says "we did marketing and it didn't work" and what they actually did was pour money into ads for a month, the first thing I review is the other three Ps, because that's where the failure usually hides.
What is marketing for?
In business terms, marketing serves three functions that feed each other. It helps you decide what to offer, because market research detects needs before you invest in solving them. It helps people find you, because the best product in the neighborhood is of little use if the people who need it don't know it exists. And it helps people prefer you, because in almost any category the customer has alternatives and needs reasons to stay with you.
There's a fourth, less discussed function that I find the most valuable: marketing is market intelligence. Done well, it tells you what people are searching for, what hurts them, how they compare options and how much they're willing to pay. That information is useful to the sales team, to product development, and even to the board when it evaluates opening a second line of business.
What are the most common types of marketing?
Types of marketing are, at their core, labels for combinations of channel and approach. These are the ones you'll run into most:
- Digital marketing: the umbrella for everything happening in online channels. If you want to go deeper, I have a full guide on digital marketing strategies.
- Content marketing: creating useful material (articles, videos, guides) that attracts your audience instead of interrupting it. I dedicated a full article to content marketing.
- SEO or search engine positioning: working to show up when someone searches for what you solve. It's my specialty, and it's why this blog talks so much about SEO positioning.
- Email marketing: the owned channel par excellence, where your relationship with your audience doesn't depend on anyone's algorithm. More details in the email marketing guide.
- Digital advertising or paid media: ads on Google, Meta, TikTok and friends. Fast for generating traffic, expensive to sustain as your only channel.
- Traditional marketing: radio, out-of-home, trade fairs, point of sale. It still works for local businesses and mass consumer goods.
The list could go on with B2B marketing, niche marketing or influencer marketing, but what matters is the order of the decisions: first you understand your customer, and only then do you choose the channel.
How does marketing work in practice?
Let me walk you through the process I follow myself, which with some nuances is the same in a large company and in a business that's just getting started.
First, research. Before spending a single dollar on campaigns you need to know what your market is searching for, what alternatives it compares and what frustrates it about the current options. Search data is my favorite source for this (I say that with the obvious bias of someone who works in SEO): if thousands of people a month search for a product category and very few search for specific brands, you have an active market that doesn't have a clear winner yet. It's an illustrative example, but the reasoning is exactly what I apply with real clients.
Second, segment. Not everyone searching for what you sell is your customer. Market segmentation helps you divide that universe into groups you can actually serve well, and a buyer persona helps you describe precisely who you're talking to.
Third, build the offer. With the customer clear, you adjust the 4 Ps: what you sell, at what price, how you deliver it and how you communicate it.
Fourth, map the journey. Between someone discovering you and buying from you there are several stages, and it pays to have them mapped in a sales funnel to detect where people are dropping off.
Fifth, measure and adjust. One metric per objective is enough to start: how many people discover you, how many consider you, how many buy and how many come back. The rest of the indicators get added when the business asks for them.
What changed with search engines and artificial intelligence?
The substance of marketing hasn't changed in decades, but the way people discover and compare has, and dramatically. More and more people ask ChatGPT or Google's AI answers directly which product to buy or which company to hire. And these systems don't evaluate just your page: they build a profile of your company with everything they can find, your site, your reviews, Google Maps, what the press says, even your job postings. With that profile they decide whether to recommend you or not when someone asks "which company can help me with this?".
For marketing, this turns consistency into a strategic issue. What your website promises, what your reviews say and what your team answers all have to tell the same story, because these systems cross-check the signals and, when they find contradictions, they simply recommend someone else. I wrote about how to work on that visibility in the SEO marketing guide.
Which mistakes should you avoid when starting out?
After years of reviewing other people's strategies, I'd say the mistakes that repeat the most are surprisingly few.
The first is starting with the channel. "We need to be on TikTok" is a phrase I hear often, and when I ask who they want to talk to there, the answer gets vague. The channel should be the last decision in the chain, after knowing who you're talking to and what you're going to say.
The second is copying the big competitor. Their strategy responds to their budget, their team and their stage. A small business competing with a multinational's tactics loses badly, but it can win in the spaces the multinational doesn't care about: specific niches, underserved areas, personalized service.
The third is not measuring, or its twin, tracking forty indicators and looking at none. If you can only record one thing this month, record where each new customer came from. That single data point already improves your investment decisions.
And the fourth is treating marketing as a campaign with a start and end date. The results that compound (the brand people recognize, the content that ranks, the email list that grows) come from continuity, and continuity requires a sustainable rhythm, even a modest one.
The takeaway for this week
If you want to do something concrete with this article, at zero cost, reach out to five recent customers and ask them three questions: how they found you, what alternatives they compared, and why they chose you. Those answers are firsthand market research, the kind consultancies charge good money for, and they'll sort out your product, price and channel decisions better than any course. With five twenty-minute conversations you'll understand your own marketing far better than with a month of posting into the void.
