When a company wants to appear on Google, having a website is not enough. There are thousands of pages competing for the same attention. And that’s where the SEO specialist comes in.
If you’re wondering what an SEO specialist is, the short answer is this: it’s the person who works to make a website visible in the organic search results. But the role goes far beyond ranking keywords.
Today, digital marketing is increasingly results-oriented. It’s not just about getting visits, but about attracting the right people. An SEO specialist helps achieve that. They analyze, plan, and optimize so that organic traffic turns into real business opportunities.
In this article, we’ll look at what an SEO specialist does, what their functions are, what skills they need, and what to consider when hiring one—either independently or through an agency.
What does an SEO specialist do and what is their role?
To truly understand what an SEO specialist does, it’s important to think about their main role: improving a website’s organic visibility with a clear business objective.
The key question is what the role of an SEO specialist is. And the answer is simple: to help a brand appear when its audience is searching for it, at the right time and with the right message.
On a day-to-day basis, the SEO specialist’s work combines analysis, strategy, and execution. It’s not just technical. It’s not just content either. It’s the combination of both, aligned with objectives such as:
- Increasing qualified traffic.
- Generating leads.
- Driving sales.
- Improving brand authority.
Everything an SEO specialist does should answer one basic question: does this help the business?
Strategic functions of an SEO specialist
At a strategic level, the SEO specialist works with information and makes decisions. Some of their most important functions include:
- Keyword research based on search intent.
- Competitor and market context analysis.
- Defining an SEO strategy aligned with the business.
- Planning optimized content.
- Prioritizing actions based on impact and resources.
These tasks help organize the work and avoid isolated efforts. A good SEO specialist doesn’t optimize just for the sake of it—they do it with a clear direction.
Technical and operational functions of the SEO specialist
In addition to strategy, there’s a technical side that’s key. This is where the specialist gets “inside” the site. Without diving into unnecessary technicalities, some of their responsibilities include:
- Technical SEO audit to detect errors.
- On-page optimization (titles, descriptions, structure).
- Improving site speed and performance.
- Reviewing indexing and crawling.
- Defining website architecture.
- Data and metrics analysis.
The goal is not only for Google to understand the site, but also for it to be easy for people to use.
What skills and knowledge should an SEO specialist have?
A good SEO specialist isn’t defined solely by technical skills. They need a combination of abilities.
On one hand, analytical skills—being able to read data, identify patterns, and make decisions based on real information. On the other, basic technical knowledge of websites, search engines, and performance. Also, content skills—understanding how to write for both people and search engines at the same time. And most importantly, business insight—knowing what’s relevant and what’s not for a company.
When it comes to tools, an SEO specialist usually works with platforms for analysis, keyword research, metrics, and tracking. The brand doesn’t matter as much as being able to interpret the data.
How to become an SEO specialist: training and experience
There’s no single path to becoming an SEO specialist—and that’s part of what makes the field interesting.
Some people come from marketing, others from communications, journalism, or programming. Some learn in a self-taught way, while others go through SEO courses or specialized training.
What all paths have in common is the holy trinity of any specialist:
- Lots of practice.
- Continuous learning.
- Trial, error, and adjustments.
SEO is constantly changing. That’s why, beyond initial training, ongoing learning is essential. Reading, testing, and analyzing real results are part of the daily work.
Freelance SEO specialist vs SEO agency specialist
When it comes to hiring, the question often comes up: is it better to go with a freelancer or an SEO agency specialist?
There’s no single answer. It depends on the context, objectives, and scope of the project.
When is it advisable to hire a freelance SEO specialist?
A freelance SEO specialist can be a good option when:
- The project is small or specific.
- A particular problem needs to be solved.
- The budget is limited.
- There’s already an internal team handling execution.
In these cases, the work tends to be more direct and focused, but it’s not always the best choice.
When is it advisable to hire an SEO agency specialist?
An SEO agency specialist is usually more suitable when a comprehensive approach is needed. For example:
- Medium- or long-term projects.
- Need for strategy + content + analysis.
- Large websites or those with multiple business units.
- Goals focused on sustained growth.
An SEO expert company like MD Marketing Digital works with a multidisciplinary team. This allows different areas to be covered without relying on a single person. SEO is integrated with content, performance, and overall digital strategy.
The SEO specialist as a strategic partner
An SEO specialist doesn’t just optimize websites. They support decision-making, analyze scenarios, and help drive sustainable growth.
Understanding what an SEO specialist is and what they do allows for better hiring decisions. It’s not just about “being on Google,” but about generating real results.
Before choosing, it’s worth evaluating the company’s digital maturity, objectives, and project scope. In many cases, working with an SEO agency specialist helps structure the work and plan for long-term growth.
If you’re considering that step, at MD Marketing Digital we approach SEO as part of a comprehensive strategy—no empty promises, just a focus on data, business, and real results.
