Beyond Blue Links: Measuring Success in the Age of Zero-Click Search
Traffic is dropping, but influence is rising. Why generic traffic metrics are dead and what KPIs you should be tracking instead.
For 20 years, the equation was simple: Rankings = Traffic = Revenue.
If traffic went down, someone was getting fired. Welcome to the age of Zero-Click Search. Gartner predicts that by 2026, traditional search engine volume will drop by 25%. Users are getting answers directly from AI, without ever visiting your site.
Does this mean marketing is dead? No. It means our metrics are outdated.
Old World vs. New World Metrics
| Metric | Old World (SEO) | New World (GEO) |
|---|---|---|
| Volume | Monthly Sessions | Share of Model Voice (SoMV) |
| Success | Click-Through Rate (CTR) | Citation Rate |
| Sentiment | Bounce Rate | Answer Sentiment |
| Funnel | Linear (Search -> Click) | "Dark" (Ask AI -> Buy) |
The Death of CTR
Click-Through Rate (CTR) measures how good your headline is. It doesn't measure how good your answer is.
In a GEO world, a user might read a full paragraph about your product, understand its value, and decide to buy it—all inside Perplexity. Your website traffic shows 0 visits. Your revenue shows +1 sale.
📊 The Reality Check: You need to track Influence, not just Visits.
The New KPI Stack
Here is what Stratos clients track instead of just "Sessions":
1. Share of Model Voice (SoMV)
How often is your brand mentioned when users ask unbranded questions about your category?
- Query: "Best email tools for cold outreach"
- Result: Does Claude mention you in the top 3?
2. Citation Rate
When your brand is mentioned, is it cited with a link? Even if users don't click, a citation is a "vote of confidence" from the AI that builds entity authority over time.
3. Sentiment Accuracy
Is the AI describing you correctly? A high Share of Voice is useless if ChatGPT thinks your Enterprise SaaS tool is a "free mobile app." Tracking structural accuracy is more important than raw volume.
The "Dark Funnel" is Getting Darker
Attribution is about to get much harder. You will see more "Direct" traffic and fewer "Organic Search" referrals.
Don't panic. This is a sign that users are finding you before they reach your site. The goal isn't to force them to click; it's to ensure that when the AI speaks for you, it says the right thing.
