# URL Unification

> **SUCCESS**
>
> **What is URL Unification?**
>
> URL Unification is a feature that consolidates data from pages that are essentially the same but have different URLs, allowing you to measure and analyze them as a single page. For example, URLs with different formatting—such as URLs with or without "www" or with or without a trailing slash "/"—can be treated as the same page.
>
> **Benefits of This Feature**
>
> **Accurate data analysis:** Prevents access data for the same page from being dispersed across multiple URLs, allowing you to accurately understand page performance.
>
> **Improved analysis efficiency:** When data is consolidated, analysis reports become easier to read, and analysis work becomes more efficient.

> **WARNING**
>
> **Note:**
>
> This setting affects data measurement. Changes only apply to new data measurements after the change.
>
> For new projects, consolidation of "www," "#," and "/" is ON by default.
>
> For projects created before April 2023, consolidation of "www" and "/" is OFF by default.

Click the gear icon next to the project name

Select Basic Settings and Tag Retrieval

Select URL Unification

Change settings for each registered domain

### URLs With and Without "www"

Default setting: ON

Example: `www.mysite.com` and `mysite.com` → Measured as `mysite.com` ❓ Change to OFF if you want to check them separately

### URLs With and Without "#"

Default setting: ON

💡 For single-page sites, OFF is recommended

### URLs With and Without "index.html"

Default setting: OFF

Change to ON if you want to consolidate `www.site.com` and `www.site.com/index.html`

### URLs With and Without "/" (Trailing Slash)

Default setting: ON

Example: `www.mysite.com/` → Measured as `www.mysite.com`

Does not apply to URLs with parameters (example: `www.mysite.com/?utm_source=google`)
