Invalid Traffic
Paid MediaAlso: IVT · Ad Fraud Traffic · Non-Human Traffic
Quick definition
Invalid Traffic (IVT) is clicks, impressions or engagement on ads that don't come from genuine human interest. It includes bots, crawlers, click farms and accidental clicks. Ad platforms split it into General Invalid Traffic (GIVT), caught by simple filters, and Sophisticated Invalid Traffic (SIVT), which needs advanced detection to spot.
Most reputable campaigns sit in the low single digits after platform filtering. Anything climbing into double digits deserves a supply-path audit.
How it varies across Australia
Invalid traffic rates vary sharply by channel. Programmatic display and social placements typically carry more invalid traffic than search campaigns, and lower-quality publisher networks carry more than premium ones. Shape matters more than any single benchmark figure.

Picture a shopfront with a foot-traffic counter at the door. Every day it clicks over a few hundred visits and you're pleased with the numbers. Except half of those clicks are the wind blowing the door open, a courier walking past twice, and someone testing whether the sensor works. Invalid Traffic (IVT) is the digital version of that noise.
IVT covers any click, impression or engagement on an ad that didn't come from a genuine human with real intent. Ad platforms split it into two buckets. General Invalid Traffic (GIVT) is the easy stuff, known bots, data centre traffic, spiders, caught by basic filters before it ever hits your report. Sophisticated Invalid Traffic (SIVT) is the harder problem, traffic designed to look human, click farms, malware-driven clicks, hijacked devices, that needs behavioural analysis to catch.
The damage isn't just wasted spend. IVT quietly corrupts click-through rate (CTR), inflates cost per click (CPC) and drags cost per acquisition (CPA) upward without anyone noticing why. Worse, if your algorithms optimise toward whatever looks like engagement, sophisticated invalid traffic actively teaches the platform to buy more of the wrong audience. Programmatic display and low-quality publisher networks carry the highest exposure. Search generally carries the least, though it isn't immune.
Invalid traffic doesn't just waste budget. It corrupts every optimisation decision built on top of the data it pollutes.
How to calculate it
IVT rate = Invalid clicks or impressions ÷ Total clicks or impressions
Worked example. Your campaign recorded 10,000 clicks last month. A third-party verification tool flags 850 as invalid. IVT rate = 850 ÷ 10,000 = 8.5%. That's 8.5% of your reported clicks that never came from a genuine prospect.
The Australian context
Australia's programmatic supply chains often route through international ad exchanges, adding hops where invalid traffic can enter undetected. Smaller local publisher networks sometimes lack the scale to invest in the verification tools bigger US or UK publishers use as standard.
The Australian Association of National Advertisers (AANA) has pushed for tighter supply-path transparency, but adoption among mid-market Australian advertisers is patchy. Businesses running programmatic or social campaigns without a third-party verification vendor are usually paying an invalid traffic tax they've never measured.

Common questions
How do I know if I'm being hit by invalid traffic?
Watch for a sudden spike in clicks with no matching lift in conversions, a CTR that looks unusually smooth, or traffic concentrated in odd hours or unfamiliar geographies. A third-party verification tool will confirm what your platform reports isn't showing you directly.
Can I get a refund for invalid traffic clicks?
Major platforms like Google Ads automatically credit detected invalid clicks back to your account, but only for what their own systems catch. Sophisticated invalid traffic that evades detection is rarely refunded because it was never flagged in the first place.
What's the difference between GIVT and SIVT?
General Invalid Traffic (GIVT) is easy to catch, known bots, data centre IPs, declared crawlers. Sophisticated Invalid Traffic (SIVT) is built to look human and needs behavioural analysis or third-party verification tools to identify.
Does invalid traffic affect SEO too?
Yes, though differently. Bot traffic can skew organic analytics, inflate bounce rate readings and distort conversion rate calculations, making it harder to judge whether content or landing pages are actually working for real visitors.
