Convertiam

Based in Santa Coloma de Gramenet, in the Barcelona area of Spain, Convertiam is a small digital marketing team, founded in 2011, that focuses on SEM for e-commerce and lead generation. The agency has held Google Partner status since 2012 and works with clients who need advanced measurement and tracking set up correctly, particularly those dealing with data quality issues in their existing analytics and advertising accounts. The declared service list covers Search Engine Optimization, Pay Per Click, Social Media Marketing, Conversion Optimization and Sales Outsourcing, with Google Ads (Search, Shopping, Performance Max) and Meta Ads described as core specialties. A distinguishing element of the work is measurement quality: the agency builds server-side tracking protocols using GTM Server-Side and GA4, incorporates offline conversion tracking and Enhanced Conversions, and applies Consent Mode v2 alongside GDPR-compliant cookie banners to preserve data while meeting privacy requirements. Technical SEO is offered alongside this measurement work, and landing page construction is included within the campaign management fee rather than billed separately. BigQuery is used for handling data from complex tracking implementations. The stated aim across these services is to feed cleaner, more accurate data into Google and Meta's advertising algorithms so that campaigns can be optimized and scaled with more reliable attribution, rather than relying on default or unaudited tracking setups.
