ABOUT SKYLEADS
Skyleads is a digital growth agency based in Athens, building full customer-acquisition systems that combine Ads, content, CRM automations, and sales support. They focus on measurable growth across the entire funnel, and with phone-call attribution at the core, they optimize based on real conversations, not just clicks.
As phone-based leads became central to client outcomes, Skyleads standardized Nimbata across all Google Ads clients and bundled it into pricing so every account starts with the same measurement foundation.
THE CHALLENGES
1. Phone conversions were invisible where decisions are made
Skyleads had no reliable way to track and send call conversions back to Google Ads, so bidding and budgets relied on partial data. There was a tooling gap that blocked true call-attribution and optimization.
2. Clients needed real-time visibility and pipeline clarity
Calls weren’t connected to HighLevel pipelines, so tracking a lead from first call to closed deal was manual and fragmented.
3. One source of truth & accountability
Without recordings tied to campaigns, Skyleads couldn’t easily validate lead quality or client feedback with real data.
4. Planning for scale without adding manual review
Growth required reducing time spent listening to recordings and moving toward automated summaries/qualification.
THE SOLUTION
Skyleads discovered Nimbata through a trusted partner and adopted it to close the call-attribution gap.
How the team uses Nimbata: Calls are attributed into Google Ads, pushed via webhooks into High Level CRM, tracked through pipelines from first call to deal closure, and recorded to assess lead quality and tune campaigns. They also use offline conversions to pass value back into Google Ads for calls that happened earlier, ensuring the algorithm learns from every revenue-driving interaction.
Nimbata is embedded in the pricing and onboarding so every Google Ads account ships with call visibility from day one.
THE RESULTS
Real estate client: scaled from 10-15 to 200+ phone conversions/month (consistently)
Significantly reduced cost per conversion while scaling volume
Improved optimization in Google Ads using accurate call data
Enhanced transparency with clients with proof beyond clicks and CTRs
“Nimbata is essential to how we run performance marketing. It gives us the call data we need to optimize, prove results, and scale.”
