How does this tool work?

Compare two URL lists or XML sitemaps to quickly identify added, removed, and unchanged URLs.

Processing runs locally in your browser from the content you paste. The tool applies deterministic parsing, normalization, and comparison rules for its specific task, then shows metrics and an exportable result. It does not fetch your website, emulate Googlebot, or replace a real crawl, Search Console, or an official validator when one is required.

How to use this tool

  1. Paste your data

    Add the HTML, JSON-LD, sitemap, text, or mapping requested by the tool.

  2. Run the analysis

    The local engine normalizes the data and applies the checks required for that tool.

  3. Review and export

    Review the metrics and generated result before using it on your site or in a workflow.

Use cases

Pre-release check

Quickly check a snippet, configuration, or list before publishing it on a website.

Migration comparison

Spot differences between versions or prepare reusable rules during a technical migration.

Local SEO diagnosis

Investigate a structural or data issue without sending the content to a remote service.

Tips and best practices

  • Use a representative copy of the content that is actually published.
  • Keep URL and casing conventions consistent when comparing two versions.
  • Cross-check the local result with a crawl or official tool when the decision depends on real server or search-engine behavior.

Frequently asked questions

Does the tool analyze my live website?

No. It only processes the content you provide in the browser. This avoids CORS limitations and keeps the supplied data local.

Does the result guarantee Google behavior?

No. It is a local structural or syntax analysis. Crawling, rendering, indexing signals, and Google processing must be checked with the appropriate tools.

Can I use the generated result in production?

Yes as a technical starting point after review. For redirects, structured data, or major migrations, always test the configuration in the target environment before deployment.
