PPC conversion tracking & measurement
Smart Bidding and reporting optimise toward whatever you measure, so the data has to be right. We set up deduplicated conversions, real values, offline imports and GA4 alignment, built with our data and analytics team, so your Google Ads run on accurate numbers.

- Remove duplicatesThe same sale counted by two conversion actions
- Remove junkSpam form fills and leads sales cannot use
- Add off-site revenueDeals that closed in the CRM days after the click
- Add real valuesMargin or deal size instead of one-size-fits-all counts
Most plateaued accounts have a measurement problem hiding underneath the bidding. Duplicate conversion actions inflate the totals, leads and sales have no value attached, revenue that closes off-site is invisible, GA4 and Google Ads disagree, and consent gaps quietly delete attribution. Automated bidding then optimises confidently toward the wrong thing. Fixing measurement is usually the highest-return work in an account.
How we set up PPC conversion tracking
Conversion tracking is a pipeline, and it breaks at its weakest stage. This is the full path we build and maintain, and what each stage protects.
The click
GCLID capture and Consent Mode v2Every ad click carries a Google Click ID. We capture it into forms and the CRM so the eventual sale can be traced back, and implement Consent Mode v2 so UK and EEA consent choices are respected without deleting your attribution.
On the site
Google tag, GTM and server-side taggingConversion actions are audited and deduplicated so one sale counts once, with real values attached. Where browsers restrict tags, server-side tagging through GTM keeps measurement accurate rather than degrading quietly.
Lost signal
Enhanced conversions and call trackingEnhanced conversions use hashed first-party data, an email at enquiry or checkout, to recover conversions cookies now miss. Call tracking turns phone enquiries into measurable conversions instead of invisible ones.
Off-site revenue
Offline conversion imports from the CRMLeads that qualify, book or close days later are imported back against the original click. Bidding stops optimising for form fills and starts optimising for the leads that became revenue.
Reconciliation
GA4 and Google Ads alignmentGA4 Key Events, Google Ads conversions and CRM totals are reconciled so the numbers agree, or the difference is explained. Budget decisions need one number everyone trusts.
Six common conversion tracking problems
All six are common, and each one changes how budget gets spent. A tracking audit checks your account against every row below.
Duplicate conversions
The same enquiry or sale is counted by two conversion actions, often a legacy tag plus a GA4 import.
Cost: CPA looks better than it is, Smart Bidding learns from inflated data, and budget scales into a mirage.
Weak primary conversions
Page views, scroll events or soft micro-goals sit marked as primary conversions.
Cost: Campaigns optimise toward cheap actions, so spend drifts to the traffic that performs the trivial action best.
Off-site sales are invisible
The platform sees the form fill but never learns which lead qualified, booked, enrolled or bought.
Cost: Bidding treats a junk lead and a £50,000 deal as equals, and the reporting cannot connect spend to revenue.
No values on conversions
Every conversion counts as one, regardless of basket size, margin or deal value.
Cost: Value-based bidding is impossible, so the account maximises volume where it should maximise revenue.
Consent gaps delete data
Consent Mode v2 is missing or misconfigured, so declined-consent clicks vanish from measurement entirely.
Cost: Attribution develops holes, reported performance sinks below actual performance, and good campaigns get cut.
Reports disagree
Google Ads, GA4 and the CRM each count conversions differently: attribution windows, models and definitions all diverge.
Cost: Every budget conversation starts with an argument about whose number is right instead of a decision.
