What is click fraud protection software?
Click fraud protection software finds paid ad clicks that come from bots, click farms, competitors or other sources with no buying intent. It tracks each visit with a script on your site, scores it, and then excludes the bad sources from your campaigns. The goal is less wasted spend and cleaner conversion data.
Google already filters some of this. Its help center says you are not charged for invalid clicks that its automated systems catch, and that clicks found later can come back as a credit. Third-party tools add a second layer for the traffic that gets through.
Most tools act in three ways:
- IP and device exclusions. The tool pushes bad IP addresses into your ad accounts so those visitors stop seeing your ads.
- Audience exclusions. On platforms like Meta, the tool builds an audience of flagged visitors and excludes it from targeting.
- Placement blocking. For Display, YouTube and Performance Max, the tool flags low-quality sites and apps so you can exclude them.

Which click fraud protection software should you pick?
Pick the tool whose entry plan covers your monthly ad spend or click volume and every ad platform you buy from. Small Google Ads accounts can start on a low flat plan.

How much does click fraud protection software cost?
Published entry prices run from $49 a month for TrafficGuard Shield, a promo price, to a $450 monthly minimum for Polygraph. ClickGuard starts at $74 a month billed annually, Fraud Blocker at $79, ClickCease Starter at $99 and Spider AF at $150 billed monthly. Lunio is quote only and aims at teams with $500K or more in annual ad spend.
Three things move the final bill:
- The plan limit. ClickGuard and TrafficGuard cap by monthly ad spend, Fraud Blocker and Spider AF by ad clicks, and ClickCease by website traffic.
- Channels. Meta, Microsoft and Performance Max coverage often sits on higher tiers, so price the plan that covers every platform you buy.
- Sites and accounts. Agencies pay more for extra domains, ad accounts and white-label reports.
How do you set up click fraud protection?
Add the vendor tracking script to every landing page, connect your ad accounts, and run in monitor mode for a week or two before you block. Check which sources it flags against your own conversion data. Then turn on automatic exclusions and review the blocked list each month.
- Start with your biggest account. Most trials connect to Google Ads first, so test where most of your spend goes.
- Mind the IP limit. Google Ads lets you exclude up to 500 IP addresses per campaign, and account-level IP exclusions also cover Performance Max. Ask each vendor how it manages that cap.
- Whitelist your own team. Add office and agency IPs so internal visits are not flagged.
- Keep claiming refunds. Google still credits invalid clicks it catches, so a third-party tool adds to that rather than replacing it.
- Fix your reports. Clean traffic changes conversion rates, so revisit your attribution software models after a month.
Frequently asked questions about click fraud protection software
What is the best click fraud protection software?
There is no single best tool for every account. TrafficGuard has the lowest published entry at $49 a month for Google Search. ClickCease and ClickGuard suit Google, Meta and Microsoft advertisers on flat plans. Spider AF is strong on placements, and Lunio and Polygraph fit larger budgets across many ad networks.
Does Google Ads refund click fraud?
Google says you are not charged for invalid clicks that its automated systems filter out. When it finds invalid clicks after you were billed, you receive a credit on a later invoice where appropriate and possible. Google does not catch everything, which is why many advertisers add a third-party tool.
How does click fraud protection software work?
The tool loads a tracking script on your landing pages and scores every paid click by IP, device, behavior and location. Visitors that look like bots, click farms or repeat clickers get excluded from your campaigns. On Google that usually means IP exclusions, and on Meta it means excluded audiences.
Is there free click fraud protection software?
No tool here offers a free forever plan, but most offer a trial. TrafficGuard gives 30 days in detection mode, and Fraud Blocker offers 7 days. ClickCease, ClickGuard and Spider AF list free trials, and Lunio and Polygraph offer free traffic audits.
Does click fraud protection work for Performance Max campaigns?
Yes, on some plans. TrafficGuard offers Performance Max Shield on its Scale plan, and Spider AF lists placement blocking for Performance Max, YouTube and mobile apps. ClickCease says it blocks bots in Performance Max through IP blocking and audience exclusions. Google also supports account-level IP exclusions that cover Performance Max.
Can click fraud protection stop fake leads?
Several tools now cover fake leads as well as clicks. Fraud Blocker verifies emails on lead forms, ClickCease adds Lead Shield for HubSpot, and Spider AF sells a separate fake lead protection product. Polygraph also says it stops bots that submit fake leads using real people’s data.
Do I need click fraud protection for small ad budgets?
Not always. If you spend a few hundred dollars a month, Google’s own filtering and manual IP exclusions may be enough. Once spend reaches a few thousand dollars a month, a $49 to $99 plan can be worth testing. Run a trial in monitor mode first and compare the flagged clicks with the plan price.
The verdict: which click fraud protection software fits your team?
Small Google Search accounts should trial TrafficGuard Shield in detection mode first. Teams that run Google, Meta and Microsoft Ads should compare ClickCease and ClickGuard, and lead generation advertisers should look at Fraud Blocker. Spider AF fits heavy Performance Max and YouTube buyers who need placement controls.
Teams spending $500K or more a year across many channels should get a Lunio audit or a Polygraph quote. Whichever tool you pick, test it on real traffic before you block.
