Bigconvert.com

BigConvert is a performance marketing agency based in Bucharest and Brașov, Romania, specializing in Google Ads, Meta Ads, and TikTok Ads for ecommerce and lead generation businesses. As a Google Premier Partner and Premium Comparison Shopping Service (CSS) Partner, BigConvert ranks among the top-performing Google Ads agencies in Romania and manages campaigns for clients across Europe.

The agency is best known for its profit-first approach to paid advertising. Instead of optimizing for ROAS alone, BigConvert builds campaigns around POAS (Profit on Ad Spend), connecting product margins, offline conversions, and cart data directly to Google Ads bidding. This means clients scale ad spend based on real profit, not just revenue.

Core services include:

• Google Ads management (Search, Performance Max, Shopping, YouTube)
• Google Shopping feed optimization and CSS advertising
• Meta Ads and TikTok Ads management
• Conversion tracking, server-side tagging, and Google Tag Manager implementation
• Offline conversion imports and profit-based bidding setups
• Marketing automation and custom reporting

BigConvert was co-founded by Ovidiu Golea and Răzvan Pepelea, who combine hands-on campaign management with engineering: the team builds its own automation systems, feed optimization tools, and data pipelines rather than relying on off-the-shelf software. This technical depth allows BigConvert to fix broken conversion tracking, recover wasted ad spend, and implement measurement setups most agencies cannot.

Typical clients are ecommerce stores and service businesses spending 5,000 to 500,000 EUR per month on paid media who want transparent reporting, direct access to senior specialists, and campaigns optimized for profit. BigConvert works in Romanian and English and serves clients in Romania, the EU, and international markets.

BigConvert.com operates as a group of four companies: BigConvert SRL, Glew Solutions SRL, Viziune Grafica SRL, and Nextgen Roi SRL.
