How Fake Conversions Can Distort Google Ads Smart Bidding
Smart Bidding optimises the conversion goals and values used by the campaign. If those signals include fabricated submissions, duplicate events or weak proxies for demand, reported success may diverge from business value. Investigate the signal definition and data path before assuming every poor outcome is caused by a bot.
Quick answer
Smart Bidding optimises the conversion goals and values used by the campaign. If those signals include fabricated submissions, duplicate events or weak proxies for demand, reported success may diverge from business value. Investigate the signal definition and data path before assuming every poor outcome is caused by a bot.

What Smart Bidding sees
Google describes Smart Bidding as optimising conversions or conversion value at auction time. Check the goals selected by the campaign and the actions contributing to them. Do not rely only on a conversion's display name: an action called Qualified lead still needs an event and acceptance rule that match that name.
Form submission ≠ qualified customer
A submit can mean the form endpoint accepted a payload. It does not establish contactability, buying authority or fit. Map the stages between receipt and a useful business outcome. Keep an explicit waiting state while sales works the enquiry, instead of treating unreviewed leads as either successful customers or confirmed spam.
The contaminated feedback loop
The conceptual risk is: low-value or fabricated event → recorded conversion → optimisation signal → further allocation toward apparently successful activity. This is an interpretation of how poor success labels can affect optimisation, not a measured forecast for every account. Establish that the event actually reaches a bidding goal before claiming campaign learning is affected.
Fake conversions vs tracking mistakes
A tag firing on button click, a duplicated import or repeated thank-you-page view can create apparent conversions without a matching new enquiry. Reconcile each event definition with the accepted server record. Correcting instrumentation and stopping fabricated submissions are different interventions; changing media targeting will not repair a duplicated tag.
Weak micro-conversions
Page views, scrolls and button presses can be useful observations, but their connection to revenue or qualified demand needs evidence. Do not sum every stage of one lead journey as multiple independent successes without an intentional value model. Review whether a cheap proxy attracts activity that meets the event rule but misses the business objective.
Moving from form fill to qualified outcome
Google supports lower-funnel categories such as Qualified lead and Converted lead. Define who makes the qualification decision, the criteria and the delay. Verify that the deeper event is measurable and adequately populated before a transition. A stricter label with inconsistent sales decisions can create a different kind of noisy signal.
First-party/offline feedback
Offline feedback requires a reliable association with the original enquiry and a correctly configured upload or integration. Review duplicates, rejected records, consent and the handling of later status changes. AdFraud.pl's traffic assessment does not imply automatic CRM integration, offline uploads or changes to Google Ads bidding settings.

Monitoring recovery after cleaning signals
Record the change date and compare cohorts after sufficient time for qualification. Monitor accepted outcomes, rejection reasons, spend and matching coverage alongside conversion volume. Sales delay, demand and media changes can affect the comparison, so an improvement after a fix is not by itself proof of causality. Set review points rather than promising a universal recovery time.
