Six weeks into a health supplement campaign across five countries, spending $11K/month on native traffic, I had a 0.7% CTR and zero conversions. Zero. I blamed the landing page for a month before I looked at the click logs.
Turns out ~60% of my clicks came from IPs that didn't match the targeting at all — "German" users with IPs geolocating to datacenter blocks in the Netherlands and Singapore. Thousands of clicks in perfect 2-second intervals, 24/7, even at 4 AM in every timezone. The pixel fired, the checkout page never loaded. Classic bot behavior.
My first verification attempt used datacenter proxies and told me nothing — ad networks fingerprint those ranges and serve different creatives to them. The only verification that matters is seeing your ads the way a real user does: real location, real network.
I rebuilt the stack with residential and mobile IPs — I use Helodata for that. The mobile pool in particular is hard to spoof, so what I see through those IPs is basically what a real cellular user sees.
The setup is simple: a scheduled job checks 30+ cities every few hours, opens the placements in a mobile browser, screenshots the creative, and cross-references against click logs. If the creative served to a Madrid mobile IP doesn't match what the platform claims, that's a red flag.
First month: cut wasted spend 68%, recovered $7K in refunds within a week by submitting the evidence.
What's your ad verification setup in 2026? Anyone still trusting datacenter IPs for geo-checks?
The IP layer runs on — their mobile pool is https://helodata.com?ref=7s9k2g what I use for the carrier-level checks.
