Site URL Comparison
Compare two URLs side-by-side. Identify differences in protocols, paths, query parameters, and fragments instantly.
How to Use the URL Comparison Tool
URLs (Uniform Resource Locators) are the address system of the web. While two links might look similar at a glance, small differences in protocols (`http` vs `https`), subdomains (`www`), or tracking parameters can lead to completely different pages or SEO issues. This tool parses two URLs and highlights exactly what is different between them.
Comparison Breakdown
- Protocol: Checks if the scheme (e.g., `https:`) matches. Security certificates depend on this being correct.
- Host: Compares the domain name and subdomain. Essential for checking redirects (e.g., non-www to www).
- Path: Analyzes the directory structure `/folder/page`. This is critical for site migrations to ensure old links map to new structures correctly.
- Query Parameters: Deconstructs the `?key=value` string. The tool identifies missing parameters, extra parameters, or value mismatches.
- Hash: Checks the anchor tag `#section` at the end of the URL, often used for jumping to specific content on a page.
Why Compare URLs?
1. SEO Audits: Search engines treat `http://site.com` and `https://site.com` as different sites. Comparing URLs helps verify that canonical tags and redirects are consistent.
2. Site Migrations: When moving content, you often need to ensure that thousands of old URLs map correctly to new ones. This tool helps spot-check patterns in your redirect logic.
3. Ad Tracking Debugging: Marketing campaigns add complex parameters like `utm_source` and `gclid`. Comparing the clicked link vs. the landing page URL helps identify if tracking data is being stripped during redirects.
