Stop Google Ads bot spam from killing your cost-per-lead
Every fake form fill you get from a Google Ads campaign is paid traffic that converted into nothing. After a month you're looking at a cost-per-lead that's 2–3× what it should be because half your "leads" are bots. SecureSMTP blocks them at the form level — five layers of invisible spam protection plus an AI classifier that reads the actual submission content. Real leads land in your CRM, fake ones get filtered before they cost you a sales-team minute.
Free forever for 100 submissions / month · no credit card.
Why your Google Ads cost-per-lead keeps climbing
- Competitors and bots target high-CPC keywords specifically because they know advertisers are paying for clicks
- Standard reCAPTCHA misses content-spam — "Hi I run a Sri Lankan SEO agency" passes the bot check but is still useless
- Without filtering, your sales team wastes hours on bad leads, and your CPL math looks worse than it is
- Google's own conversion data gets polluted, so the algorithm starts optimising for the wrong "conversion"
Block at the form, not after
Filter spam before it touches your CRM, your sales team, or your conversion tracking. Cleaner data top-to-bottom.
AI reads borderline cases
Layer 5 is an AI classifier that reads the actual submission content. Catches social-engineering and pitch spam standard CAPTCHAs miss entirely.
No conversion friction
No CAPTCHAs for real visitors. Your ad clicks convert at the same rate (or better). You just stop paying to entertain bots.
Questions, answered
Won't bots just adapt?
Each of our 5 layers is independent — bypassing one doesn't bypass the others. The AI classifier in particular doesn't fail-open: even a perfectly-formatted bot submission gets flagged based on content.
Does this affect Google's ad optimisation?
It improves it. Cleaner conversion data → Google's algorithm optimises for genuine leads → CPL drops over time as the auction shifts toward your real-buyer audience.
Will my analytics still see spam submissions?
No — blocked submissions don't fire your conversion pixel. We respond "success" to the bot (silent rejection) so they can't probe what triggered the block, but conversion tracking only fires on real leads.
How do I integrate with my CRM?
Email forwarding is automatic. For HubSpot/Pipedrive/Salesforce, the Pro plan adds direct webhook delivery. Zapier also works.
How much spam will this catch?
In our own production traffic, the 5 layers catch 99.4% of bot-driven submissions. The AI classifier adds another ~3–5% of content-pitch spam that bot-detection alone misses.
