I’m Ben Collier, a Google Ads specialist and performance marketing consultant based in Barcelona. I bring 3+ years of hands-on and advisory experience across ecommerce, SaaS, lead generation, and brand awareness. Through a Google-backed advisory programme, I have consulted on hundreds of accounts spanning every vertical and business type—from early-stage advertisers building their first campaigns to established brands managed by agencies with six-figure monthly budgets.
I pair strategic depth with technical fluency: full-funnel growth strategy, campaign architecture, ad strength optimization, keyword analysis, feed management, and tracking setup. As a freelancer, I tailor engagements to what each client actually needs—ongoing management, a one-off project, or strategic advisory. Being part of a certified Google Partner network gives me access to beta features and advanced reporting tools to surface insights others can’t.

Industry Experience
eCommerce · Performance Max · Brand Search · Demand Gen · Creative Testing
This clothing brand had underperforming campaigns with low ROAS and no clear growth strategy. I rebuilt the entire account structure — starting with segmented PMax asset groups by gender, product category, and messaging, followed by Brand campaign setup to capture high-intent demand, and Demand Gen expansion for visual channel growth.
Creative and targeting testing ran throughout to continuously improve efficiency. The account went from barely breaking even to a consistently profitable, scaling channel.
Result: Core ROAS 1–2x → 4x · Brand campaigns 8x · Demand Gen ~$50K revenue
eCommerce · Performance Max · Merchant Center · Feed Optimisation · A/B Testing
This cosmetics brand had Performance Max campaigns running but performance had plateaued. The existing structure lacked proper asset group segmentation and the product feed had quality issues affecting how products were being served.
I rebuilt the PMax structure with segmented asset groups, cleaned and optimised the product feed in Merchant Center, ran continuous A/B tests across creatives and audiences, and refined bidding strategy throughout. Performance improved consistently over the campaign period.
Result: ROAS grew from ~3x to 7–9x
Lead Generation · YouTube · Demand Gen · Funnel Optimisation
A hobby-based online course business was using YouTube Shorts for demand generation but struggling with conversion efficiency. I analysed the funnel end to end — targeting, creative alignment, and campaign structure — and rebuilt the approach around what was actually driving course purchases.
Optimisations focused on audience refinement, creative-to-landing page alignment, and bidding strategy to improve conversion rate while scaling spend.
Result: ~1,000–1,500% ROAS (10x–15x) while scaling
eCommerce · Google Search · Performance Max · Demand Gen · Merchant Center
This brand was running Meta ads only and had never used Google Ads. I built the entire channel from scratch — starting with Search campaigns to validate demand, followed by Merchant Center setup, product feed upload, and Performance Max launch.
Once the core campaigns were profitable, I expanded into Brand campaigns and Demand Gen to capture intent at every stage of the funnel. The account went from zero Google Ads history to a fully scaled, profitable acquisition channel.
Result: ~5,000% ROAS (50x return) from a cold start
