IVT is any ad impression never seen or interacted with by a real human. It splits into two main types: General Invalid Traffic (GIVT), which is easy to detect and largely auto-filtered by platforms, and Sophisticated Invalid Traffic (SIVT), which is engineered to look human. This is where real money is lost.
Why Does It Exist? Follow the Money.
- Zero barrier to entry — anyone can register a site, join an exchange, and start monetising bots.
- Supply chain has too many hops — your DV360 bid travels through DSP → Exchange → SSP → Publisher.
- Arbitrage launders it — middlemen buy cheap fraudulent traffic and resell it at higher CPMs.
The Anatomy of Ad Fraud
| SIVT Type | What It Does |
|---|---|
| Botnets | Infected real devices simulate browsing on residential IPs |
| Pixel Stuffing | Ads crammed into a 1×1 invisible pixel — impression counted, never seen |
| Ad Stacking | 10 ads layered in one slot; only the top one visible, all 10 billed |
| Domain Spoofing | Fraudsters fake premium domain referrers (e.g., pretending to be NYT.com) |
| Click Farms | Humans or scripts clicking ads at scale with zero purchase intent |
Who's to Blame?
Everyone in the ecosystem holds a piece of the puzzle — but not equally.
- Fraudsters build and operate the bot networks. They're the criminals.
- SSPs/Exchanges are gatekeepers who sometimes look away because more inventory equals more fees.
- You, the advertiser, are the last and most powerful line of defence.
If you're running an open-auction campaign with no third-party verification and no exclusion lists, you're actively funding a bot network right now.
How to Fight Back in DV360
1. Activate Native Fraud Protection
DV360's built-in IVT filtering is on by default. In Line Item → Brand Safety, confirm Google's protection is active. Weight spend toward Programmatic Guaranteed (PG) or Private Marketplaces (PMP) over open auction.
2. Add a Third-Party Partner
Use industry leaders like IAS, DoubleVerify, or Moat:
- Enable pre-bid segments (Targeting → Third-Party Verification)
- Set thresholds to "Avoid", not just "Monitor"
- Run post-bid tags on every line item for MRC reporting
3. Lock Down Your Inventory
Enable ads.txt and app-ads.txt filtering — only buy from authorised sellers.
- Build a master exclusion list of known fraud domains
- Exclude MFA sites, parked domains, and unverified apps
- Concentrate spend through TAG-certified SSPs
4. Review Domain Reports Weekly
Flag anomalies like:
- CTRs > 0.5% on display with zero conversions
- Near-zero time-on-site despite high spend
- Unknown domains generating significant budget

The 60-Second Takeaway
IVT is an ongoing drain, not a one-time risk. The traders who protect their budgets don't necessarily have better creative — they just make sure more of their impressions reach real people.
Checklist before your next campaign goes live:
- 🛡️ Google native IVT active?
- 📊 Pre-bid 3rd-party running?
- 📝 ads.txt filtering enabled?
- 🚫 Master exclusion applied?
- 🔍 Weekly domain reviews?
- ⚙️ Thresholds set to "Avoid"?
Two or more "no" answers? Your budget is subsidising bots. Fix it today — the impact shows up in your very next campaign.
