Tracking nobody owns
The web developer thinks the PPC person did it. The PPC person thinks the web developer did. Google Ads carries on counting anyway.
Developers who got fed up with bad tracking
Zestcode Conversions is a specialist conversion tracking team, made up of UK developers who have built bespoke platforms and API integrations for over seven years.
We fix conversion tracking and connect CRM and ERP data to the ad platforms, so bidding learns from real sales, real order values and real profit. We don’t run your campaigns, and everything we build lives in your own accounts.
Why tracking needs developers
Conversion tracking sits awkwardly between marketing and engineering, so it often belongs to nobody. Marketers can see the numbers look wrong. Fixing why usually means tags, APIs, CRM fields and hashed data.
That’s the part we do. We found a duplicate conversion action on our own Google Ads account, built ourselves a daily check so it wouldn’t happen again, and realised plenty of other people needed the same thing.
Bidding on the wrong signal
Every form fill looks like a win, so Smart Bidding goes off and finds more of the cheapest ones, whether or not they ever buy.
Systems that never met
The CRM knows who bought. The ERP knows what they spent. The ad platforms know neither, because nobody introduced them.
How we work, and what we won’t do
Developers first. We’d rather fix a tag than present a deck about it.
Developers, not a marketing agency
Zestcode has spent over seven years building Laravel, WordPress, Shopify and API integrations. We read the API documentation, write the code and test what it sends, which is most of what this work comes down to.
Built in your own accounts
Everything goes into your Google Ads, GTM, Cloudflare and CRM accounts rather than a platform of ours. Walk away tomorrow and every tag, trigger and connection stays put, with no lock-in.
Fixed prices, agreed first
The audit and setup packages are fixed price, and each sync gets a fixed quote once we’ve scoped it. You’ll know the number before anyone opens GTM.
Consent respected, data hashed
Customer emails and phone numbers are hashed before they reach Google, and only sent where the consent signals allow it. When a visitor says no, the setup takes that at face value.
One thing, done properly
We fix tracking and connect business data to ad platforms. GA4 dashboards, general analytics consulting and conversion rate optimisation are left to other specialists, and we don’t manage campaigns either.
An audit that can come back green
If your tracking is sound, the report says so and there’s nothing to buy. Take the findings, stop there, and we’ll part on good terms.
The team behind it
Every setup is delivered by a small, specialist development team that builds bespoke platforms and integrations. If your orders need automating as well, our sister practice Zestcode Automation does exactly that.
