Before you can stop click fraud, you have to see it. Didva is click fraud detection software focused on visibility. It records every paid click, scores it against dozens of signals, and shows you where invalid activity is concentrated by campaign, keyword, geo, device and source.
The hardest part of click fraud isn't blocking, it's knowing where it's happening. Ad platform dashboards show clicks and conversions, not which sources are suspicious or why. Without that diagnosis, teams either ignore the problem or block blindly and risk excluding real customers.
How the signal stack works
Detection quality is decided by what you measure, not by a single magic signal. Each paid click is evaluated across layered evidence. Network signals first: the IP address, its ISP or ASN, whether it belongs to a datacenter or proxy range, and its geography. Then device and browser signals: the user agent, and fingerprints that betray automation frameworks pretending to be human visitors.
Behavior seals the verdict. Real prospects scroll, navigate and dwell; bots bounce in milliseconds or repeat identical patterns on a timer. Repeat-click frequency, session timing and engagement depth are compared against what genuine buyers on the same campaign do. No single signal condemns a click — the combination does, which is what keeps false positives down.
Reading a flagged click
Every flagged click opens into a full record: the campaign, ad group, keyword and landing page that paid for it, the IP and its network owner, the device and fingerprint evidence, the session's behavior trail, and the specific reasons the score crossed the line, with a confidence level attached.
That record is the difference between detection software and a black box. You can defend a decision to a client, attach it to a Google Ads invalid-click refund claim, or overrule it when you know something the model doesn't — like an office IP that legitimately clicks your ads every day.
From diagnosis to action
Detection is deliberately separated from enforcement. You can run in monitoring mode indefinitely — many accounts start with a few weeks of pure observation to build a baseline of where invalid activity concentrates before blocking anything.
When the picture is clear, findings flow into the prevention layer: exclusion lists, automatic blocking of high-confidence threats, and a review queue for borderline cases. That workflow is covered in depth on the click fraud prevention software page.

Real feedback from teams protecting their paid traffic with Didva.
Caught a click-farm pattern our previous tool missed and cut wasted spend within the first month.
Setup was a single snippet. The evidence export made our Google Ads refund request painless.
Clear per-IP reasons and a review queue so we are not blocking real customers. Exactly what we needed.
Datacenter and repeat-click detection paid for itself fast. Reporting is clear enough to share with clients.
We manage campaigns across several clients and the dashboard quickly highlighted traffic patterns we would have otherwise missed.
Simple setup, useful alerts, and enough detail to investigate suspicious visitors without involving developers.
The product delivered value quickly. I would like a few more filtering options, but the core detection features work well.
The manual review queue helped us avoid blocking legitimate visitors while still dealing with suspicious traffic.
The IP-level evidence makes client conversations much easier. Instead of assumptions, we can show actual data.
One of the cleaner interfaces we have used in the ad fraud space. Reports are easy to understand.
Within the first week we found a source of repeated clicks that had been consuming budget for months.
Useful notifications, clear reasoning, and very little noise. Most flagged visits deserved attention.
We mainly wanted better visibility into traffic quality. The platform delivered exactly that.
I like that every flag includes supporting details. It builds confidence in the decisions being made.
We tested several tools and this was the easiest one to explain to both clients and team members.
Good balance between automation and transparency. Nothing feels hidden behind a black box.
The repeat-click reports helped us identify unusual traffic spikes during a competitor campaign launch.
Client reporting became much easier once we started including the exported traffic quality reports.
Strong product overall. A few advanced reporting features would be nice, but detection accuracy has been solid.
The value was obvious after the first couple of weeks. We now review suspicious traffic as part of our regular workflow.

What is click fraud detection software?
It is software that monitors paid clicks and scores suspicious ones so you can see where invalid activity is happening: by campaign, keyword, source and more, before deciding how to respond.
How is detection different from prevention?
Detection is about visibility, finding and diagnosing invalid clicks. Prevention adds blocking and exclusions on top. Didva does both; this page focuses on the detection and reporting layer.
Can I see why a click was flagged?
Yes. Every flagged click comes with a risk score, the signals behind it and a confidence level, plus exportable evidence.
How quickly are clicks scored?
Clicks are scored in real time or near real time as paid visitors reach your landing pages.
Do I have to block traffic to use it?
No. You can run Didva purely for monitoring and reporting, then enable blocking workflows whenever you're ready.
