1. Free diagnosis
I check what's public on your site: what Google receives, what's indexed and which serious errors there are. You get it in writing.
Technical SEO: I make Google see your site the way your customers do
Many sites look fine in the browser and reach Google empty. I check what your site actually delivers to the search engine, fix it and show you the proof.

<title>Home</title><div id="root"></div>→ Google received an empty page.
This is the first thing I check.
The problem almost nobody checks
A site can look perfect and serve Google an empty page, repeated titles or routes that don't exist. Your platform's dashboard says everything is fine. The HTML the crawler receives says otherwise.
How I work
2. Technical audit
Every finding with its impact and its recommendation, verified against production. You know what to fix first and why.
3. Execution and verification
I apply the changes or work alongside your team, and I check the result on the published site, not in the editor.

Result: Positioning decided: technical SEO consultant. Four days after indexing, the home page already ranks 1 for my name; the rest gets measured in October.
Read the keyword research caseWhat sets me apart: I verify before I claim
I use AI every day and I don't believe it until I've checked. A tool can say something is missing when it's there, or give you a number from a single run that doesn't repeat. That's why every finding in my reports comes with its proof: the server response, the served HTML or the repeated measurement.
That rigor comes from my other craft. I've spent years interpreting between English and Spanish, medical consultations included, where an approximate word changes the meaning. That's why I work well in sectors where a mistake has consequences, like the legal and financial ones in my cases.
What I don't do
- Paid link building
- Ad campaigns
- Social media management
- Mass content writing
I'd rather do one thing well: get your site to Google complete and clear.
