ProSEOBuilder is a Madrid-based search marketing agency that architects ranking strategies the way engineers build bridges — with load calculations, stress tests, and zero tolerance for guesswork. Your competitors rank because someone built their SEO. Let us build yours.
Five engineering-grade services — each with transparent pricing, measurable KPIs, and a money-back performance clause.
A 500-checkpoint crawl that exposes every technical flaw, keyword gap, and competitor advantage hiding in your site. Delivered as a prioritised blueprint with estimated traffic impact per fix.
Research-driven articles, pillar pages, and topic clusters built to capture search intent and convert readers into customers. Written by human specialists, not AI generators.
White-hat outreach to DR50+ publications. Digital PR, guest placements, niche edits, and HARO campaigns that build real authority — not spam that gets you penalised.
