From technical debt to the first million impressions.

// HVAC · BARCELONA · SINCE 2026

JAG Alcaide has been installing heating, air-conditioning and plumbing systems in Barcelona since 1953. Its website had spent years piling up technical issues that held back its visibility on Google. In 45 days, we changed that.

// The challenge

A working website. Broken SEO.

JAG Alcaide had been online for years, but its website carried serious technical debt: redirect chains, duplicate H1s on more than 150 products, recurring server errors, misconfigured hreflang and a homepage slider that wrecked LCP. Google crawled it badly and ranked it worse.

The content existed but wasn't optimised: short service pages, no semantic structure, no guide prices, no FAQ schema. And the Google Business Profile, while active, hadn't been worked on. The starting point was clear: clean up first, grow second.

Phase 2 under way. The trend is confirmed.

Google has absorbed the Phase 1 changes and the results are arriving: June 2026 is the best month in the site's history. Phase 2 — page-by-page optimisation so every URL is Google's best answer in its category — is under way, and the data keeps improving week by week.
