Examples

1. Cleaning Referral Traffic

Marketing Analyst

Background

I have a raw export of referral URLs from Google Analytics that includes full paths and subdomains, making it hard to see which sites are driving traffic.

Problem

I need to aggregate traffic by root domain to get a clear overview of top-performing websites.

How to use

Paste the list of referral URLs into the tool and select 'Root Domain Only' mode.

extractionMode: root

Outcome

A clean list of unique root domains, allowing for quick grouping and analysis of referral sources.

2. Security Log Auditing

System Administrator

Background

I am reviewing server access logs and need to identify all unique subdomains being accessed by users.

Problem

The logs contain full URLs, which makes it difficult to quickly scan for unauthorized subdomains.

How to use

Paste the log URLs into the tool and enable 'Include Subdomains' to maintain the full hostname structure.
