What Is a Traffic Quality Score?
A Quality Score (traffic quality score) is a 0-100 score ClickSentinel assigns to every click, reflecting how likely it is to come from a real user rather than a bot, VPN, or fraudulent click. The higher the score, the more trustworthy the traffic; scores below 50 usually warrant further investigation.
How the Quality Score is calculated
The score starts at 100 and is reduced for each risk signal detected: the IP belongs to a datacenter/hosting provider (large deduction), the IP is a known VPN or proxy (moderate deduction), the IP is a Tor exit node (very large deduction), the click duplicates another within a short window (under 5 minutes), and abnormal click velocity from the same source within an hour. Each signal carries its own configurable weight, combined into a final score.
Score ranges and what they mean
- 80-100: Highly reliable traffic, very likely a real user.
- 50-79: Worth monitoring — some risk signals present but not conclusive fraud.
- Below 50: Real risk — review the traffic source, especially if it makes up a large share of total clicks.
Why IP checks alone aren't enough
Many tools stop at checking whether an IP is a VPN. But sophisticated fraud can use a clean residential IP. That's why the Quality Score also factors in behavioral signals (velocity, duplication) and IP reputation data accumulated across many websites, catching cases where the IP looks "clean" but the behavior is abnormal.
Practical uses of the Quality Score
The Quality Score tells you exactly what percentage of your ad budget is being wasted on junk clicks, lets you export an IP blocklist for Google Ads or the server level, and lets you compare traffic quality across different ad channels to allocate budget more effectively.
Why a single number is so useful
Raw logs are overwhelming — thousands of clicks, dozens of IPs, endless timestamps. A single 0-to-100 score per click collapses all of that into a decision you can actually act on. Instead of asking "is this IP suspicious," you ask "what share of today's traffic scored below 50," and the answer points straight at the budget you are losing. It also makes trends visible: if your average score drops week over week, something changed in your traffic mix and you can investigate before it eats your results.
From score to action
A score only matters if it changes what you do. Use it to build an exclusion list for the worst offenders, to compare channels so you fund the ones sending real people, and to set a threshold below which traffic gets blocked automatically.
