ClickDefender vs Didva

ClickDefender is a paid click-fraud protection service for PPC campaigns on Google Ads and Microsoft Ads. It uses a JavaScript tracking script, real-time detection, analytics, IP blocklists, API access, and alerts. The maker says its AI evaluates clicks across more than 50 signals, including browser fingerprints, scroll depth, time on page, click patterns, and other behavioral indicators, to identify bots, click farms, and competitor activity. Dashboards report traffic sources, IP addresses, geographic distribution, device types, and fraud trends. Google Ads can receive blocked-IP exclusions every six hours, up to 500 IPs per campaign. Microsoft Ads automation is listed as in development; users can export a blocklist for manual import. Slack alerts and HTTP webhooks send fraud events externally. Setup supports JavaScript or Google Tag Manager, with guidance for WordPress, Shopify, Wix, Squarespace, and custom HTML. Plans start at £49 a month, with a seven-day trial requiring a payment method and converting to a subscription unless canceled.

Didva monitors paid advertising clicks to detect and block click fraud in real time. The service says it evaluates more than 50 signals per click, including IP reputation, device fingerprint, click velocity, and behavior. High-confidence threats can be sent to exclusion lists, while other traffic can be held for manual review. Reports show click-level details such as IP address, device fingerprint, origin, and flag reason, with evidence export for Google refund claims. Integrations include Google Ads, Meta Ads, Microsoft Advertising, and a REST API for custom connections. Didva says ad accounts can be connected through one-click OAuth without DNS changes or a developer. Blocking options include automatic Google Ads IP-exclusion syncing, custom rules, and an allowlist. The free Watchtower plan includes detection across ad channels, manual IP blocking, and a weekly digest, but excludes automatic enforcement, CSV export, Meta Ads protection, and daily reports. Starter costs $39/mo and Growth costs $89/mo. Didva cautions that no detection system catches everything.
