How this list was built
Each entry is drawn from that vendor's own pricing and product pages, cross-checked where possible against independent third-party software directories (Capterra, GetApp, Software Advice, G2). No vendor besides ClickPurity paid for or reviewed their placement. Where a vendor's pricing or detection method isn't publicly disclosed, that's stated plainly rather than filled in with a guess.
Six factors evaluated for every tool:
- Which ad platforms it actually covers, per the vendor's own site
- Whether pricing is publicly published or requires a sales conversation
- What detection signal the vendor states its approach is built on
- Whether blocking is automatic at every tier, or gated behind a higher plan
- Independent review volume relative to any customer-count claims made
- Whether refund-claim or evidence-generation support is mentioned as a feature
The Thirteen Tools, Side by Side
ClickCease
The most established name in this category by most measures, with the largest customer base and most third-party reviews.
ClickGuard
Leans hardest into customizable, rule-based control: more configuration, more precision if you want it.
Clixtell
Started as a call-tracking company. Click fraud protection is a second product line, with a distinctive video session recorder.
Lunio (formerly PPC Protect)
Positions itself around self-learning, minimal-configuration detection, with the broadest platform coverage on this list.
TrafficGuard
Positions itself around real-time IP scoring and network-wide enforcement, with a strong presence in app-install and programmatic fraud alongside search.
Fraud Blocker
The closest match to ClickPurity on pricing and detection approach among the tools in this list, though with a thinner independent review presence relative to its claimed customer count.
Spider AF
Really three products in one: click fraud, fake lead detection, and website security scanning, positioned as a broader "digital marketing security platform."
ClickFortify
A newer, aggressively low-priced entrant. The $8/month price is well-documented, but independent reviews are still very thin (1 published review at the time of writing).
TrafficShield
A cloaking platform first, fraud filtering second, built for affiliate and performance-marketing workflows rather than straightforward click fraud detection.
ClickPatrol
Genuinely well-reviewed among the newer entrants, with a specific credible use case in regulated industries like financial services.
Sila
A small, newer tool covering Google and Meta with city-level targeting precision, priced above most of the category.
Budgetguard
The newest and cheapest tool in this comparison, with a free version available but only a single published review at time of writing.
ClickPurity
Our own product, built specifically and only for Google Ads, with device fingerprinting as the primary detection signal.

How to Actually Narrow This Down
Three questions cut this list down fast, in the order that matters most.
Which platforms do you actually advertise on? If it's Google Ads only, ClickPurity and ClickGuard's Google-specific strength matter more than Lunio's broader multi-platform coverage, which you'd be paying for without using. If your spend is genuinely split across several platforms, that breadth becomes the deciding factor instead.
Do you want to see pricing before talking to anyone? ClickGuard, Clixtell, and ClickPurity all let you see exact numbers on their own site. Lunio and, for full tier detail, ClickCease require more of a sales conversation.
Do you want flat pricing or spend-based tiers? ClickPurity is flat regardless of ad spend. ClickGuard and Clixtell scale with spend or click volume. At higher budgets, that difference in pricing philosophy can matter more than any single feature.
Frequently asked questions.
Bottom line: click fraud protection isn't about blocking everything that looks unusual — it's about being precise. ClickPurity identifies the specific device behind a fraudulent click, not just its IP, so your budget reaches real buyers instead of bots and competitors.
