Microsoft Ads click-fraud protection, without the guesswork
Microsoft doesn't allow automated IP blocking through its advertising API. So we focus on the hard part, catching the fraud, and show you exactly which IPs are wasting your Microsoft Ads budget, ranked worst-first and ready to exclude.

- You protect Google Ads, but not Bing.
- Search Partner clicks never seem to convert.
- You don’t have time to dig through IP logs.
Microsoft Ads fraud: the overlooked problem
Fewer advertisers protect their Bing ads, so fraudsters go where it’s easy.
Most businesses focus their fraud protection on Google Ads and forget about Microsoft Ads entirely. Fraudsters know this. Lower scrutiny, fewer monitoring tools, and less advertiser awareness make Microsoft Ads an attractive target for click fraud operations.
The misconception is that Microsoft Ads has less fraud because it has less traffic. The reality is the opposite. In our October 2026 benchmark, Microsoft Ads clicks were almost twice as likely to be high risk as Google Ads clicks: 7.7% against 3.9%. Part of the reason is that Bing has fewer protections in place. Fewer advertisers use third-party fraud tools on Microsoft Ads, which means fraudsters face less resistance.
If you spend $3,000 to $5,000 a month on Microsoft Ads, our October 2026 benchmark puts about $230 to $385 of it on high-risk clicks. That adds up to $2,800 to $4,600 a year that should be driving real leads and sales.

Track every Microsoft Ads click
Every Microsoft ad click carries an ID. We use it to trace each fake click back to where it came from.
The msclkid parameter is Microsoft's click identifier. ClickGuardian uses it to give you complete visibility into every click on your Microsoft Ads.
What Is msclkid?
Microsoft's unique click identifier, appended to every ad click URL. Like Google's gclid, it lets you trace every visit back to the exact click that triggered it.
How We Use It
We match each msclkid against our fraud detection engine, linking device fingerprints and behavioural data to the specific Microsoft Ads click for accurate attribution.
What It Reveals
See which keywords attract the most fraud, identify high-fraud campaigns and ad groups, and calculate the exact cost per fraudulent click on your Microsoft Ads.

A straight answer on "automatic" Microsoft blocking
Unlike Google, Microsoft's advertising API doesn't support programmatic IP exclusions. Full stop. Any tool claiming to silently auto-sync IPs into Microsoft Ads via the API can't actually do it. So we don't pretend to. Instead, we do the hard 95%: catch the fraud with 100+ signals, then hand you a ranked, ready-to-paste exclusion list: worst budget-wasters first, trimmed to Microsoft's per-campaign limits. Pasting it in takes a couple of minutes, and you stay fully in control of your account. Prefer a hand? Just ask and we'll share your flagged IP list ready to exclude.
One platform, two ad networks protected
Google Ads and Microsoft Ads, one script and one dashboard.
Single Script
One line of JavaScript protects both Google Ads and Microsoft Ads traffic. No separate installations, no code duplication.
Unified Dashboard
Compare fraud rates across Google and Microsoft Ads side by side. One login, one view, complete visibility into your ad spend protection.
Shared Intelligence
A fraudster detected on Google Ads is flagged on Microsoft Ads too. Cross-platform intelligence means no blind spots between networks.
Why unified protection matters
- Fraudsters target both platforms. Protecting only one leaves you exposed on the other
- Attack patterns transfer between platforms: block on one, pre-empt on the other
- More cost-effective than separate tools for each platform
- Simpler management: one dashboard, one script, one subscription

No budget is too small for fraud protection
Even on a small budget, the money lost to fake clicks adds up fast.
Think your Microsoft Ads budget is too small to justify fraud protection? The maths says otherwise.
The maths on small budgets
- 1 $2,000/month spendA modest Microsoft Ads budget
- 2 7.7% high risk = $154/month at riskFrom our October 2026 benchmark
- 3 $154/month = $1,848/yearEnough for another month of ads
Real example: local plumber
- $1,500/month on Microsoft AdsEmergency plumbing services, local area
- 12.2% of clicks with warning signsThe October 2026 benchmark rate for drainage, plumbing and heating
- $183/month at risk = $2,196/yearRanked IPs ready to exclude in Microsoft Ads
ROI is actually higher for smaller budgets because every wasted click has a proportionally larger impact on your campaign performance.
