Real case: web redesign and SEO for an online store
How I rebuilt a store that was failing and worked its technical SEO. Below are the intervention and how its sales moved between January and May 2025.
See the figures and the context of this case
Work started in December 2024. WordPress redesign on Divi, published February 2025. Cleanup of duplicated plugins, plus technical SEO on sitemap, robots.txt and broken URLs returning 404.
| Month | Sales (COP) |
|---|---|
| January | $1,025,689 |
| February | $2,548,080 |
| March | $3,587,456 |
| April | $8,081,879 |
| May | $13,289,661 |

Real case: the SEO problem hidden inside the articles
A manual review found injected phrases and malicious links. How I cleaned the site and worked its SEO recovery, with results documented from November 2024 to May 2025.
See figures, intervention and context
A professional services firm whose identity stays confidential. A previous penalty had already been resolved when I started; reviewing article by article uncovered content that was still compromised.
I removed the malicious insertions, migrated hosting, applied security hardening and submitted a disavow file to Search Console. The SEO work also covered robots.txt, sitemap, canonicals, redirects, image and metadata optimisation, and informational content.
| Indicator | November 2024 | May 2025 |
|---|---|---|
| Organic clicks | 153 | 1,180 |
| Google impressions | 4,300 | 22,000 |
| Organic users | 188 | 1,550 |
| Organic CTR | 3.6% | 5.4% |
| Average position | 23.9 | 10.2 |
| Indexed pages | 4 | 96 |
Source: tracking report provided by María Fer. This compares two points in time; no monthly series is available here. The growth corresponds to the period of cleanup, migration and SEO work, and is not attributed to any single action.
Per my own monitoring, no further malicious links were detected during the time I worked with the firm. That is a statement about the monitoring period, not a security guarantee.
Three sites, three priorities: protect, capture, measure
An ongoing project: I found unauthorised content, genuine enquiries buried in spam, and analytics data from two sites mixed together. Here is what I found, what I did, and what is still open.

An anonymised sample of a web maintenance and basic SEO service across three sites. Status per the August 2026 documentation and the closing analysis of 1 September. The three fronts overlap; they are not one problem per site.
- Protect: removed unauthorised content on two sites, applied technical and SEO fixes, and enabled security measures. A full security review and part of the hosting work are still open — removing the content does not prove the intrusion is resolved.
- Capture: classified form submissions and identified legitimate enquiries buried in spam. Protection and field adjustments are configured but, per the log, not yet published. There is no record that the identified contacts were followed up.
- Measure: documented data from two sites mixed into a single analytics property. The technical cause and its fix are still open. Search Console access is now available for all three sites.
| Audit indicator | Before | After |

| Issues detected | 44 | 11 |

How we can work
The capacity you need, with a direct relationship.
One defined task, or ongoing support for your agency's deliverables.
Let's resolve one defined deliverable.
An audit, a landing page, or the QA of a migration. We agree scope and acceptance criteria before anything starts.
- Defined deliverable
- Scope and price agreed up front
- Documentation and review
A direct working relationship
You know who you're talking to, and who is behind the delivery.
I plug into your agency's work and turn technical needs into deliverables you can review and put in front of your client.
Before we start we agree priorities, access, scope and how we collaborate. During the project, decisions are documented as we go.
Let's talk about your next deliveryFrequent questions
Before we work together, you can ask me this.
What kind of work can I hand over?
Technical SEO, migrations, web maintenance, landing pages and QA. First we understand the task, then we agree the collaboration model that fits it.
Can you work under my agency's brand?
Yes. I can work as internal support, fully under your brand, or as a named specialist in front of your client — decided per project.
How do you show a case without revealing the client?
I show the problem, the intervention and the technical evidence, with no company, names, domains, URLs, logos or identifiable data published.
Do I need a call to get started?
Not necessarily. You can send the initial context and we decide together whether a call is needed to close scope, access and dates.
