Click fraud protection software should do more than count suspicious clicks. It should stop them and show you why. Didva monitors every paid click, scores the risky ones, blocks the worst offenders and keeps your conversion data clean, all from one dashboard.
Paid campaigns attract more than buyers. Bots, click farms, proxy users, repeat competitors and accidental clicks all spend your budget without any intent to convert. Left unchecked, that invalid traffic inflates your costs, lowers your conversion rate and pushes automated bidding in the wrong direction.
Protection means detection plus prevention
"Click fraud protection" gets used loosely, so it's worth being precise about what a complete product includes. Detection is the visibility layer: recording every paid click and diagnosing where invalid activity concentrates, by campaign, keyword, geo, device and source. Prevention is the action layer: automatically excluding high-confidence threats and filtering bots so the same sources can't keep spending your budget tomorrow.
Didva ships both in one product. If you want to understand either layer in depth, the detection software page covers how scoring and diagnosis work, and the prevention software page covers the automated blocking workflow. This page is the overview of the whole system, what it costs, and how to start.
What it costs
Pricing is published and self-serve. The Watchtower plan is free forever: up to 3,000 clicks per month, no credit card, no trial countdown, enough for smaller accounts to run continuous monitoring at no cost. Paid plans start at $39/month, billed monthly with no annual contract, and the price you sign up at is the price you keep.
That structure matters in this category, where introductory rates, spend-based caps and quote-only pricing are common. You can compare the published plans on the pricing page before creating an account.
Platform coverage today
Didva protects Google Ads, Microsoft Bing and Meta (Facebook and Instagram) campaigns live today; Meta protection is included on every paid plan. Every paid click on a covered platform is tied back to the campaign and keyword that paid for it, scored in real time, and eligible for exclusion workflows and refund-evidence exports.
If your spend is concentrated on platforms outside that list, check the coverage row before committing — the free tier makes it cheap to verify that your traffic is being seen correctly.

What advertisers say
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.

Start Protecting Your AdsFrequently asked questions
What is click fraud protection software?
It is software that detects suspicious or invalid paid clicks, blocks the worst sources, and gives you the evidence to keep your campaigns and conversion data clean.
What kinds of click fraud does Didva catch?
Didva targets bots, click farms, proxy and datacenter traffic, repeat competitors and low-quality or accidental clicks that show no real buyer intent.
How does the blocking work?
High-risk IPs and sources can be added to exclusion lists for your ad platforms and to site-side blocking, automatically for high-confidence threats and after review for borderline cases.
Will it cause false positives?
Borderline traffic is held for human review rather than blocked outright, and every decision comes with the signals behind it so you stay in control.
Can I export evidence for refunds or clients?
Yes. You can export click-level logs with IPs, timestamps, user agents and campaign context for invalid-click investigations and client reporting.
