Unusual clicks or weak enquiries can have several causes. A defensible investigation identifies the pattern and supporting records without accusing a competitor or publisher on the basis of disappointing results.
What you will leave with: Prepare a focused traffic-quality case and reconcile any platform response with billing evidence.
Use this when
- A sudden click spike produces little useful activity.
- A stakeholder believes a competitor is deliberately exhausting the budget.
This is not a fraud-detection guarantee or permission to collect invasive identifiers.
Describe the anomaly precisely
Record when the pattern started, affected campaigns and the observed change. Compare spend, clicks, destination activity and suitable outcomes on compatible clocks. Check whether a campaign expansion, promotion or tracking release could explain the movement.
A high bounce rate or low conversion rate does not establish invalid traffic. People can be genuine but poorly matched to the offer. A broken page can make valid clicks look worthless. Preserve these alternative explanations so the investigation does not turn into a search for evidence supporting a predetermined accusation.
Read platform filtering and billing separately
Google describes filtering invalid activity and issuing appropriate credits when invalid activity is detected after billing. Review the available invalid-traffic indicators and the actual billing adjustment records. A filtered interaction and a credited charge are not the same accounting event.
Do not assume a reported invalid-click count represents money paid and lost. Conversely, do not assume automated filtering proves every questionable interaction has been resolved. Record exactly what the platform shows and which concern remains unexplained.
Build a narrow evidence package
Use authorized aggregate logs and relevant campaign records to locate the pattern. Keep timestamps, affected placements or campaigns and the definitions of each metric. If a support investigation is warranted, prepare the provider’s required evidence through the approved channel.
Minimize personal data and avoid installing unapproved tracking tools merely to obtain more detail. Do not publish suspected identities or retaliate against a rival. The question is whether delivery or billing needs correction, not how to identify someone to blame from an ambiguous traffic signature.
Resolve the operational problem as well
If the issue is poor relevance, improve the targeting or message through the authorized workflow. If it is a broken destination, repair the experience. If the provider confirms invalid activity, reconcile the response and any credit with the affected period.
Keep unresolved cases labeled unresolved and assign a review date. Document what the evidence established and what remains a hypothesis. A useful outcome may be a reliable explanation rather than a refund. Avoid promising either reimbursement or complete protection from future invalid activity.
Make the reasoning concrete.
A hypothetical campaign’s clicks double after a targeting expansion while enquiries remain flat. Invalid-traffic reporting also shows some filtered clicks. The team initially attributes the entire increase to competitor fraud.
Accuse the competitor
Opening: Treat low conversion and filtered clicks as proof of deliberate interference.
Hypothesis: Some invalid activity may exist.
Risk: The expansion and poor-fit traffic are plausible alternative causes.
Investigate the stages
Opening: Review scope changes, destination health, filtered activity and billed adjustments.
Hypothesis: Each explanation can be evaluated with relevant evidence.
Risk: The available data may not identify a responsible person.
Address the verified cause, escalate only the supported unresolved concern and avoid claims about competitor intent.

Pattern
What changed, where and when?
Alternatives
Could targeting, offer or tracking explain it?
Filtering
What activity was already excluded?
Billing
Which charges or credits actually exist?
Escalation
What evidence and authorized channel support an investigation?
Watch for the wrong conclusion.
- Equating low quality with fraud.
- Treating filtered clicks as automatically billed losses.
- Accusing competitors without evidence.
- Collecting invasive identifiers to satisfy curiosity.
Your next action
Write a traffic-quality incident note with observed facts, alternative explanations and one precise unresolved question.
