Invalid Traffic Guide for Google Ads: GIVT vs SIVT Explained

What is invalid traffic?

Invalid traffic refers to clicks and impressions that advertisers did not intentionally target or that lack genuine user interest. Industry standards (IAB/MRC) split this into GIVT (General Invalid Traffic) and SIVT (Sophisticated Invalid Traffic).

GIVT — General Invalid Traffic

GIVT is traffic easily caught by automated filters:

• Known search engine crawlers (Googlebot, etc.)
• Simple script-based clicks
• Obvious bot traffic from datacenter IPs
• Preview and test traffic

Google filters most GIVT automatically — advertisers are typically not charged.

SIVT — Sophisticated Invalid Traffic

SIVT is harder to detect and causes the most PPC damage:

• Bots simulating human-like behavior
• VPN/proxy geo-spoofing
• Click farms
• Ad stacking, pixel stuffing and other ad fraud techniques
• Competitor-driven repeat clicks

SIVT can look like normal visitors in standard analytics. This is why third-party click fraud protection tools are essential.

How invalid traffic hurts your budget

Every invalid click:

• Costs money directly on CPC campaigns
• Trains Smart Bidding with wrong signals
• Lowers conversion rate and distorts bid strategy
• Exhausts daily budget before real customers see your ads

Layered defense strategy

Effective invalid traffic defense is layered:

1. Tighten geo, device and schedule targeting in Google Ads
2. Maintain IP exclusion lists regularly
3. Use real-time click protection software like Shield
4. Track Google's invalid traffic refund process
5. Analyze referrer and landing page behavior

Shield combines GIVT and SIVT signals into a risk score and automatically blocks suspicious IPs.
