I Studied SEO, SEM, and Web Analytics at Tecmilenio

I studied SEO, SEM, and Web Analytics at Tecmilenio. I was very happy about it because I felt that some projects that were technically working well weren't generating any revenue. And I knew that was partly because I wasn't properly analyzing what was happening on each website. I already knew most of the SEO stuff: page load speed, tags, data structure. I was already doing those things. The difference is that now I have a deeper understanding of their purpose from the search engine's perspective, not just the developer's. Optimizing because it's good practice is not the same as optimizing because you know how Google decides whether or not you appear in search results. SEM was a bit harder to learn. Spending money to get immediate traffic is tricky, assuming that simply building something will work on its own. But it makes sense when the client needs results in weeks, not months. I learned to design Google Ads campaigns focused on conversions, not clicks, and to avoid confusing the two. Gaming for Google Ads (GA4) and Google Tag Manager were the most useful things in the long run. Now I have a framework for understanding user behavior after they arrive: what they abandon, what they convert, and where they get lost. Before, I made decisions based on intuition; now, at least, I have data to back them up. With this, I have enough context to decide whether a digital strategy makes sense or if it's better to make changes to achieve the goals we, as developers, are pursuing and what the client is looking for.
