What is a lead: types, qualification and scoring
Complete guide to leads: what they are, the difference between MQL, SQL and PQL, how to qualify them and how to build a basic lead scoring system.

Sevilla es centro económico del sur de España con un mercado digital en crecimiento. Las búsquedas de "agencia seo sevilla" (900 búsquedas/mes) reflejan un mercado que busca mejorar su presencia digital. Pero la mayoría de empresas cometen el mismo error: invierten en traer tráfico y se olvidan de convertirlo.
Los sectores más activos en Sevilla — servicios profesionales, despachos de abogados, clínicas y consultoras — invierten en SEO, Google Ads y redes sociales. Pero cuando el usuario llega a la web, se encuentra con:
El resultado: dinero que entra por la puerta del tráfico y sale por las grietas de una web mal optimizada.
Los servicios profesionales sevillanos — despachos, clínicas, consultoras — tienen webs que reciben tráfico local pero no convierten. Formularios de contacto pobres, propuestas de valor poco claras y cero tracking de conversiones. Optimizar estos elementos básicos puede duplicar los leads sin invertir más en publicidad.
Our methodology is always the same, regardless of the client location:
We analyze your website with GA4, heatmaps, session recordings and business data. No opinions — data.
Every action is prioritized by revenue potential, not by ease of implementation.
A/B testing and personalization to validate every change before permanent implementation.
We don't measure clicks or page views — we measure euros. Every test has an estimated billing impact.
