How It Works
This tool uses a normalization algorithm to compare URLs. When you click check, it processes each line through a standardizer:
Process(URL) = Trim() → Lowercase() → StripProtocol() → StripQuery()It creates a "fingerprint" for each URL. If two different lines produce the same fingerprint (e.g., example.com/page/ and example.com/page), they are flagged as duplicates based on your settings.
Practical Examples
🇮🇳 1. E-commerce Product Cleanup
Scenario: A store owner in Delhi has a product list where some links have /product/ and others have /product/?id=123.
Action: Using "Ignore Query Params", the tool identifies these as the same page, preventing duplicate content issues in the sitemap.
🇺🇸 2. Migration Audit
Scenario: An SEO agency migrates a site from HTTP to HTTPS. The report contains mixed links.
Action: Using "Ignore Protocol", the tool treats http://site.com and https://site.com as duplicates, helping consolidate the final list.

Scenario: A marketing team merges three email lists containing profile URLs.
Action: The tool instantly removes 500+ exact duplicates, saving money on email marketing credits.
What is Duplicate URL Checking?
Duplicate URLs occur when the same page is accessible via multiple web addresses. This confuses search engines, wastes crawl budget, and splits ranking power. A bulk checker helps you consolidate these lists effortlessly.
