How SealMetrics Calculates SEO Traffic

SealMetrics is designed to classify traffic sources with precision while maintaining strict privacy compliance.
This document explains how SEO (organic search) traffic is detected and how we avoid misclassifying paid Google Ads traffic.

1. SEO Traffic Definition​

SealMetrics attributes a visit to SEO traffic when the following two conditions are true:

✅ Condition 1: The referrer is Google​

Recognized Google domains include:

  • google.com
  • google.<country> (e.g., google.es, google.fr, google.de)
  • googleusercontent.com
  • googleapis.com

Any hit from a Google domain may be considered SEO traffic.

❌ Condition 2: No advertising parameters are present​

If the landing URL contains any of the following parameters, it is not SEO traffic:

  • gclid (Google Ads auto-tagging)
  • gad
  • gbraid
  • wbraid
  • Newly introduced Google Ads identifiers
  • Any utm_ parameter (utm_source, utm_medium, utm_campaign, utm_term, etc.)

🟦 If BOTH conditions are met → SealMetrics classifies the hit as SEO traffic​

Example:

Referrer: https://google.com/search?q=analytics+tools
Landing URL: https://yoursite.com/pricing
Parameters: none
Result: SEO Traffic

2. Avoiding Confusion with Google Ads Traffic​

A common question:
“Could Google Ads traffic ever be classified as SEO traffic?”

✔️ SealMetrics keeps this risk extremely low — under 1%.​

For misclassification to happen, TWO things must occur simultaneously:

  1. The referrer must be Google

  2. The landing URL must contain no advertising identifiers:

    • No gclid
    • No gad, gbraid, or wbraid
    • No utm_source, utm_medium, etc.
    • No value-track parameters from templates

Why this is rare:​

  • Google Ads auto-tagging almost always adds gclid
  • Manual UTM tagging is standard practice
  • Google continuously introduces new ad identifiers, all of which SealMetrics detects

Result:​

If any ad-related parameter exists → SealMetrics classifies the hit as Paid Traffic, not SEO.
