This is my Story

What motivated me to become an SEO?

I am a very curious person, which is why I started learning programming when I was 13 years old. Later, I began applying that knowledge to web programming. However, I always saw it as a hobby, as I was afraid of losing my passion if I took it as a job.

There came a time when my curiosity grew, and I was not only interested in how websites worked, but I also wanted to know how those websites were seen and found by others. After all, this is usually the ultimate goal of a website.

This led me to start in the SEO world, specifically as an intern at a software company in Germany in 2016. Since then, I have been improving and progressing professionally in this sector.

My professional experience, along with my programming background, has allowed me to better understand how websites and search engines really work.

I had to learn everything on my own and faced a lot of misinformation. Although there is a lot of information available about SEO, it is not so easy to get it right when it comes to technical SEO.

What I hope for you, the visitor of this website, is to save you part of the journey that this initial learning curve entails. I want to guide you so that, unlike me, you do not waste time with so much information overload and can focus on knowledge that will really help you.

For all these reasons, I decided to launch Asdrubal SEO S.L., a place where I believe I can work on this discipline in the way that I love.

Software:

It's quite common to find SEOs who depend on plugins and can't work outside of WordPress. I believe that the technology used should best fit the project, and SEO should not limit it.

There are a lot of frameworks, libraries, CMS, and file formats. Here are the technologies and types of pages I am used to working with:

Nginx

Vanilla JS

Vue.js

WordPress

Apache

XML

Robots.txt

PDF

Multimedia

Angular

Laravel

CSS3

PHP

Next.js

Gatsby.js

React

Symfony

All these technologies I present are directly related to SEO. My experience is not limited to these software, but I showcase them because they are the most directly related and the ones I work with regularly. I've omitted SEO tools like analytics tools, server management, and others, assuming that any professional SEO knows how to handle them. These tools serve to streamline the work.
