Web development with technical SEO

Sites that index at 95–97% Lighthouse and capture transactional traffic. I design the information architecture around conversion, optimize images and headers, and ship the local SEO B2B companies actually need.

Google Search Console — Greenhouse Plastics SEO case Frank Cardona

Real results

50 leads in 3 months. 97% PageSpeed.

Technical SEO isn't theory — it's verifiable metrics. At Greenhouse Plastics Colombia the site I built generated around 50 leads in 3 months with deal sizes between 20 and 50 million COP, in a highly transactional technical niche. At Chonta Lab I hit 97% PageSpeed Insights and 95% SEO with deep indexation.

Every page I deliver passes the 10 critical SEO modules: optimized title 30–60 chars, unique meta description, absolute canonical, full Open Graph, Twitter Card, JSON-LD schema matched to page type, hreflang where applicable, proper lang tag, sitemap and robots, GEO meta tags for local business.

My technical stack

Static HTML5 served from Hostinger with an .htaccess that forces HTTPS, redirects www↔no-www, caches aggressively and compresses with gzip. Critical CSS inlined, async fonts (preload + onload), hero with fetchpriority="high" and WebP. Zero heavy frameworks dragging down Lighthouse.

Frequently asked questions

What people ask the most

What makes SEO-first web development different?+

A site built with technical SEO from day one indexes fast on Google, loads under 2 seconds, hits Lighthouse 95–97%, and captures transactional traffic from specific keywords. It's a sales tool — not a digital brochure.

What real results do you have?+

At Greenhouse Plastics Colombia I delivered around 50 leads in 3 months, with deal sizes between 20 and 50 million COP. At Chonta Lab I achieved 97% PageSpeed Insights and 95% SEO. Every project is measured with the client's own numbers.

Do you work with WordPress or custom development?+

Static HTML on Hostinger for maximum speed and SEO control. WordPress only when the client needs to publish content constantly without going through a developer. Never heavy templates that wreck Lighthouse.

How long does an SEO web build take?+

One-page sites with full SEO: 5–10 days. Multi-page sites with case studies, blog and local SEO: 2–4 weeks. Fast delivery is the standard.
