Task Summary

Deployed an intrusion-detection alerting layer across PPC landing pages
Flagged bot/threat traffic patterns (rate bursts, repeated submissions, spoofed fields)
Scored inbound leads for spam risk before they reach sales/CAD
Automatically blocked repeat offenders from the current and all future PPC sites
Recorded block decisions centrally so a bad actor cannot return under a fresh variant
Reduced the cost of PPC leads materially by filtering spam before spend is wasted

Detection & Response Logic

Signature-based & behavioural scoring of submissions (volume, timing, field anomalies)
Rate-limit and blacklist registry shared across every PPC domain
Real-time alert notifications on suspected attack or spam bursts
Persistent blocklist preventing future sign-up/funnel access from flagged users

Technical Details

Spam-Filtering Cost Impact

With a shared, persistent blocklist tied to form validation and submission throttling, the volume of junk leads reaching the CRM and PPC budgets dropped significantly. Genuine enquiries retained through, while cost-per-lead improved - a measurable reduction in wasted paid-spend caused by spam traffic.
