Digital marketing uses online channels to raise awareness of an offering, attract interested people, and guide them toward an inquiry or purchase. If you are starting from scratch, you need to understand your audience, choose an objective, and learn to measure a relevant action. This guide explains the concepts and first exercises without assuming prior knowledge.
Basic digital marketing concepts
The starting point is a simple question: whom do you help, and what do you need that person to be able to do after finding you? A company may want to receive inquiries, sell on its website, or gain subscribers. That objective guides the message, the channel, and how the work is evaluated.
SEO helps search engines find and understand your content; social networks let you publish and interact; email maintains communication with people who agreed to receive it. Digital advertising distributes ads using a budget, and content marketing answers questions through articles, videos, or other resources. PPC means pay per click: it is an advertising billing model, not a name for all digital advertising. You can combine channels, but first you should know what role each one plays.
Tools for taking your first steps
You do not need to learn every tool at once. Start with a place to explain your offering, a channel for reaching your audience, and a way to check whether people take the expected action. Before opening accounts or paying for licenses, write down what decision you will make using each tool’s information.
Google Analytics is used to analyze interactions on a website or app when configured. Google Ads and Meta Ads let you manage advertising in their respective environments. They do not serve the same purpose. As a first exercise, define whether you want to observe a visit, a click, or a submitted inquiry, and check that the record corresponds to that action. The Google Analytics events documentation explains the difference between automatic events and events you need to implement.
How to understand your audience and its intent
Knowing your audience means understanding what problem people are trying to solve, what questions they have, and how they compare alternatives. Avoid focusing solely on age or location. For example, someone searching for a definition needs a different explanation from someone already comparing providers. This is an example of search intent: the need behind a query.
Research, ask questions, and observe. You can conduct surveys, review inquiries your team has already received, and analyze customer data responsibly. Group recurring questions and write a clear answer for each one. On social media, observe which topics generate conversations related to your offering, without confusing a popular trend with a need your audience has.
How to create content that answers questions
Turn a real question into a useful piece of content. If you sell a service people do not yet understand, explain what it includes and how to purchase it before asking for a meeting. You can adapt the same idea to several formats while maintaining the message and the level of detail each channel needs:
- Write an article explaining a common question with examples.
- Create a social media post with a clear idea and a relevant action.
- Produce a video showing how a product or service works.
- Design an infographic organizing steps, verified data, or comparison criteria.
Test formats you can produce and maintain. For a blog, develop the answer with examples; for a video, show a process; for an infographic, organize brief, verifiable information. Creativity helps when it makes the idea easier to understand. Review accuracy, readability, and a next action before publishing.
How to choose a social network to start with
Choose networks where your audience looks for information or discusses topics related to your offering. Also consider which formats you can sustain and who will respond to messages. You do not need to be on every platform to get started: a focused, actively managed presence lets you learn which questions arise and what content is useful.
Facebook, Instagram, X (formerly Twitter), and LinkedIn have different audiences, formats, and uses. Do not choose a network simply because it has many users. As an exercise, compare two platforms: what your audience publishes, what questions people ask, what format you would use, and how much work maintaining it requires. This comparison guides an initial choice; it does not guarantee results.
Recommendation systems change, and there is no formula that guarantees reach. Observe the response to your posts and compare content with the same objective. Likes may show interest, but a relevant inquiry or a visit to the right page provides different information. If there are not enough data, avoid drawing conclusions from an isolated post.
A recommendation for getting started: answer a specific question, make the next step easier, and review what happened before repeating the action.
Your first digital marketing exercise
To practice, write down who your audience is, what problem you solve, and what action you want to facilitate. Prepare a page or post that answers a question, share it on a relevant channel, and record the response. Review what people understood and which questions remained unanswered. This lets you improve the content without constantly changing your objective.
Explore digital marketing courses and communities to keep learning. Once you know these concepts, go deeper with the guide to choosing channels and building a digital strategy. If you need to connect your company’s activities, learn about Agencia Cero’s integrated marketing service, whose scope is defined for each project.
Are digital marketing and digital advertising the same thing?
Advertising is one part of digital marketing. An ad requires media spend; an article, an email, or a website improvement also requires work, but not necessarily payment for distribution. Choose each activity according to its function and record its costs so you can make an informed comparison.
What do SEO, AEO, and GEO mean?
SEO refers to optimization for search engines. AEO is used to describe content prepared to answer questions; GEO, work on its understanding and visibility in generative systems. To get started, define concepts clearly, answer directly, and cite sources where appropriate. Google explains that its AI features in Search rely on standard SEO practices. No technique guarantees a ranking or that an AI will cite your website.
