SEO case studies
A selection of projects where organic rankings have been built from different contexts, sectors and business models. Each file will be documented with its starting point, the work carried out and the results that can be verified publicly.
Rankings are not shown as if they were permanent, and work carried out under other brands is not attributed to La Policía del SEO. The goal is to document real experience, not to make commercial promises.

Google Ads experience
Six years managing Google Ads with real investment
Albert's experience with Google Ads doesn't come from a demo account or an isolated campaign. For six years he has managed the advertising for Alsobre.com, his own affiliate marketing project specialized in mattresses and sleep products.
In this business model, users reach Alsobre through an ad, browse the content and can move on to an external store through an affiliate link. Profitability doesn't depend solely on getting cheap clicks: it depends on those users moving through the funnel, buying at the retailer and generating a commission large enough to cover the investment.
Over a twelve-month period, the account accumulated 157,000 clicks and €23,300 in ad spend. The average CPC was €0.15, with monthly budgets that have typically ranged between €1,000 and €3,000.
The recorded cost per conversion was €0.36, but that metric needs context. The Google Ads conversion didn't represent a final purchase: it represented the click through which the user left Alsobre to visit one of the affiliated stores.
Of the users who moved on to the stores, roughly 3.8% ended up buying. The average commission received per sale was around €50. That's why evaluating the campaigns couldn't stop at CTR or CPC: it had to connect the cost of acquiring traffic with downstream behavior and the economic value generated off-site.
A low CPC alone doesn't prove a campaign is profitable. This project required interpreting several layers of the funnel: ad click, content engagement, affiliate click, external purchase and commission. That experience is the foundation of La Policía del SEO's Google Ads service.

The Google Ads cost per conversion corresponds to the outbound click to the affiliated store. The purchase happened afterward on an external website.
