ClickDefender vs ClickHelm

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.

ClickHelm is click-fraud protection that identifies devices and can block people rather than relying on IP addresses. It evaluates device characteristics, network type, click identifiers, and on-site behavior to produce a named risk score. Blocking is not automatic unless a customer creates a rule to enable it. The free edition records and scores visitors, identifies VPNs and crawlers, and counts calls, WhatsApp messages, forms, and orders, but does not block visitors. Paid plans add blocking and may include Google Ads reporting, rules, alerts, or client reporting. Detection and blocking cover traffic from Google Ads, Meta, Microsoft Ads, TikTok, organic search, and direct visits, while campaign spend matching is specific to Google Ads. ClickHelm runs as a web service or can be self-hosted on WordPress 5.6 or newer, PHP 7.2 or newer, and MySQL or MariaDB. Visitor data remains in the customer's WordPress database, though visitor addresses may be sent for VPN, proxy, Tor, or data-centre classification. ClickHelm starts recording after installation and does not import historical traffic. Paid plans start at $29 a month.
