About Mireia

I help companies grow organically and better convert that traffic. In recent years I have worked with B2B and e-commerce companies: from SEO migrations without traffic loss to projects that have gone from 1,400 to 476,000 impressions and from 32 to 5,040 monthly clicks.
I also design conversion rate optimization (CRO) programs with A/B tests, the latest project improved form conversion by 197%.

How can I help you?
  • Analyze why your website is not generating the expected results and define a clear improvement plan.
  • Perform SEO and CRO audits (including UX audit) to improve visibility, user experience, and performance.
  • Optimize conversion and user experience to transform traffic into revenue.
  • Design and structure websites (or redesign them) with a focus on conversion and business.
  • Identify growth opportunities through data, user behavior, and funnel analysis
  • Improve content and structure to align SEO with search intent and conversion.
  • Test, iterate, and optimize (A/B testing) to make data-driven decisions.
If your website has traffic but is not generating the results you expect, I can help you understand what's failing and how to improve it.
