The Performance Leak

Every fake click drains your ROI.

Ad fraud is no longer just lost money. It is a systemic threat that corrupts your campaign data, poisons your AI learning, and funds competitors' bot networks.

Peak Ad Fraud Rate

Algorithm Corruption

P-Max and similar automated campaigns can mask up to 2× higher fraud rates. If your AI is learning from bot traffic, it will keep optimizing toward it, creating a feedback loop that degrades performance.

Direct Budget Waste

MFA (Made-for-Advertise) sites act as budget black holes. With a 14× volume explosion, these sites exist solely to siphon your media spend.

Frequently Asked Questions

What is Click Fraud?
Click fraud involves creating fake ad impressions, clicks, and conversions to exhaust advertising budgets. Predicted to cost advertisers $50 billion (¥6.4 trillion) annually by 2025, ad fraud is a significant threat driven by malicious bots.

Fraudsters aim to profit by offering false metrics, using techniques like click farms, click flooding, and SDK spoofing.

Spider AF specializes in click fraud protection, offering advanced detection and prevention solutions to protect digital advertising campaigns.
How does Spider AF ensure Click Fraud Prevention?
Spider AF Tracker is installed on websites to provide owners with comprehensive traffic insights. While website owners decide when to activate the tracking tag, it's recommended to install it on all pages for maximum effectiveness.

Once deployed, Spider AF Tracker scans and analyzes device and session-level metrics, including page locations, referrers, IP addresses, and user agents. Sophisticated algorithms identify signs of bot behavior, enhancing ad fraud detection capabilities.
How does Spider AF detect Invalid Traffic?
Spider AF employs sophisticated techniques to detect both general and sophisticated invalid traffic. General invalid traffic includes crawlers, data centers, and invalid user agents, while sophisticated invalid traffic comprises bots, fake user agents, repeated clicks, invalid IP addresses, and domain spoofing.

Our detection methods analyze IP addresses, user agent data, and browsing patterns to identify and prevent fraudulent activity, ensuring ad campaigns reach genuine audiences and maximize ROI.
How does the Free Trial work?
The Spider AF trial offers full access to the Elite plan for two weeks. During this period, Spider AF analyzes your site's status without activating blocking features, ensuring adequate data collection while minimizing the impact of outliers.

You'll have visibility into all detected invalid activities and access to features like placement and keyword insights. Spider AF continuously monitors your webpage's traffic to ensure correct setup of configurations.
