Frequently asked questions.
What is BigConvert and what does it do? +
BigConvert is a digital and performance marketing agency specializing in eCommerce. We run Google Ads, Facebook Ads, Google Shopping Ads, Feed Management, POAS and Dynamic Ads campaigns for brands in Romania and Europe that want to grow profitably, not just spend ad budgets.
What is POAS and why is it better than ROAS? +
POAS (Profit on Ad Spend) measures the real profit generated for every euro spent on advertising, factoring in cost of goods, margin and operating expenses. ROAS (Return on Ad Spend) only measures gross revenue against ad spend - it can look good on paper even while you're losing money on some products. BigConvert optimizes campaigns for POAS to grow real profitability.
What makes BigConvert different from other marketing agencies? +
We don't just manage campaigns - we build data-driven performance marketing systems: POAS optimization, advanced Feed Management, weekly A/B creative testing, precise tracking and Dynamic Ads. We also built ProductXL.com, which gives us hands-on eCommerce experience on top of our marketing agency perspective.
How does BigConvert's free audit work? +
The free audit includes: a review of your existing Google Ads and Meta Ads accounts, an assessment of tracking and attribution, a Feed Management analysis, and pinpointing budget leaks and POAS growth opportunities.

How do you measure the success of online ad campaigns? +
We use real metrics: POAS, ROAS, CPA, MER (Marketing Efficiency Ratio), conversion rate, profitability by product and channel - not vanity metrics (reach, impressions without context). Every report clearly shows how much was invested and how much profit each campaign generated.
Which advertising platforms do you manage? +

Feed Management means optimizing the product catalog (titles, attributes, prices, images) sent to Google Merchant Center, so your products show up in relevant searches and drive profitable conversions.
How do I choose a digital marketing agency for eCommerce? +
Look for an agency specialized in eCommerce with proven experience in Google Shopping, Meta Ads and POAS, that reports transparently and shows real data - not just ROAS. BigConvert offers a free audit to see if we're a good fit.
