Specialist Google Ads and airtight tracking for ecommerce brands done guessing.

Diligent is a performance-marketing agency for ecommerce brands, founded in 2018 and based in Belgrade, Serbia, working with clients worldwide. We do two things and we do them properly: specialist Google Ads management, and airtight web analytics and conversion tracking. Most agencies sell traffic. We start one step earlier, with the measurement, because you cannot optimize what you cannot trust. A typical account comes to us with a gap between what the reports claim and what actually happened. We find it, fix it, and build a model the client can finally act on. Only then do we scale. We began as a PPC-only shop and learned to build landing pages, then analytics, then entire funnels, because traffic only pays when the funnel and the measurement underneath it are sound. Today we run as three departments, advertising, analytics, and creative, that work as one team. Accounts are run in-house by our own senior specialists, not handed to a junior farm. The person who builds your account is the person who explains it on your call. Our pricing is a flat retainer plus a performance share, never a percentage of your ad spend and no hidden fees, and you own everything we build: the accounts, the tracking, the creative. We are a certified Google Partner and a Microsoft Advertising Partner, with work spanning ecommerce verticals from skincare and cookware to jewelry, mattresses, motorcycles, and B2B manufacturing.

Description
Airtight web analytics and conversion tracking, because you cannot optimize what you cannot trust. We rebuild GA4 from scratch, implement server-side tagging, and close the gap between what the reports claim and what actually happened, so the numbers you act on hold up. Most accounts come to us with a reporting gap; we find it, fix it, and give you a measurement model you can finally make decisions on. You own every account, tag, and dashboard we build.
