URL Compare Tool

A URL compare tool breaks down two web addresses into their individual parts and shows you exactly where they differ. URLs have several components - the protocol (http or https), the domain name, the path, query parameters, and fragments. This tool analyzes each piece separately so you can quickly identify what's different between two URLs that might look almost identical at first glance.

It's useful for SEO work, debugging website issues, checking redirect targets, and making sure your canonical URLs are set up correctly.

There are several situations where comparing URLs becomes important.

• Canonical URL issues. If your site has multiple URLs pointing to the same content (with and without trailing slashes, www vs non-www, http vs https), search engines might see them as duplicate pages. Comparing URLs helps you spot these variations.
• Tracking parameter problems. Marketing campaigns often add UTM parameters or other tracking codes to URLs. Comparing the base URL with a tracked version helps you verify the parameters are correct.
• Redirect debugging. When a redirect isn't working as expected, comparing the source URL with the destination URL can reveal what's changing during the redirect.
• Link audits. When checking backlinks or internal links, you might need to verify that linked URLs actually match your target pages.

Every URL can be broken down into several components.

• Protocol. Usually "http" or "https" - this tells the browser how to connect to the server. HTTPS is the secure version and is preferred for SEO.
• Domain. The main address like "example.com" or "www.example.com". The www prefix is technically a subdomain.
• Port. Usually hidden because browsers use default ports (80 for http, 443 for https), but sometimes explicitly specified like ":8080".
• Path. The part after the domain that identifies a specific page, like "/blog/my-article". Paths are case-sensitive on most servers.
• Query string. Everything after the "?" symbol, containing key-value pairs like "?id=123&sort=date". These parameters pass data to the page.
• Fragment. The part after the "#" symbol, like "#section-2". This tells the browser to scroll to a specific part of the page. Fragments are not sent to the server.

URL differences can create real SEO problems if not handled properly.

• Duplicate content. If Google sees "example.com/page" and "example.com/page/" as two different URLs with the same content, it might split your ranking signals between them or pick the wrong one to show in search results.
• Protocol mismatches. Having both http and https versions of your pages accessible can cause duplicate content issues. You should redirect all http traffic to https.
• Parameter variations. Session IDs, sorting parameters, and tracking codes can create hundreds of URL variations for the same page. Use canonical tags to tell Google which version to index.
• Case sensitivity. Some servers treat "/Page" and "/page" as different URLs. This can accidentally create duplicates if your internal links are inconsistent.

This tool helps you spot these issues by making URL differences obvious.

Yes. This tool runs entirely in your browser using JavaScript. The URLs you enter never leave your computer or get sent to any server. You can disconnect from the internet after loading the page and the tool will still work perfectly.

This makes it safe to use with internal URLs, staging environments, or any addresses you would rather not share with third-party services.
