This project is under continuous development, expect bugs and unimplemented features.

SEO Macroscope for Microsoft Windows is a free and open source website broken link checking and scanning tool, with some technical SEO functionality.

More information about how SEO Macroscope may be used for everyday tasks may be found in the blog at https://nazuke.github.io/SEOMacroscope/blog/.

The most recent installer may be found under the project releases area on GitHub at:

https://github.com/nazuke/SEOMacroscope/releases

It is highly recommended to uninstall the previous version of SEO Macroscope before installing a newer version.

The C# solution is now being developed with Visual Studio 2017.

Open the solution in Visual Studio 2017 or later, ensure that the references are satisfied, set build to Debug, compile and run.

Enter the URL of the website to scan into the Start URL field, and then click the Start button.

Depending on the size and responsiveness of your website, it may take a while to complete the scan.

There are still going to be many bugs in this version, and many features and functions remain to be implemented.

However, it is functional enough to be used for many link checking tasks right now.

• Reporting broken, redirected, and other types of issues.
• Reporting metadata about each found URL.
• Generating an HrefLang Matrix, for multilingual websites.
