Quick Questions

Do I need a credit card to start?

No. Your trial is completely free for 30 days. After that, we send you a report and an invoice with 14 days to review. If you're not convinced, simply don't pay - no automatic charges, ever.

What's the difference between Click Fraud Prevention and Conversion Screening?

Click Fraud Prevention blocks invalid traffic automatically - bots, data centers, known bad actors, and ad platform failures. Conversion Screening goes further by applying your business rules to filter out real visitors who won't convert - wrong location, wrong language, VPN users, repeat clickers. Other services only do the first part. JunkShun does both.

How hard is installation?

One line of code added to your site's header, before your ad platform scripts. If you've ever added a Google Ads tag or Meta pixel, you already have the skills. No developer required.

Will this block real customers?

The fraud prevention layer catches patterns that legitimate visitors never exhibit. The conversion screening layer is entirely under your control - you set the geofences, rate limits, language rules, and anonymizer sensitivity to match your business. You can also whitelist any IP address at any time.
