Announcing: IIS SEO Toolkit v1.0.1

Last week we released a refresh for the IIS Search Engine Optimization (SEO) Toolkit v1.0. This version is a minor update that includes fixes for all the important bugs reported in the IIS.NET SEO Forum.

Some of the fixes included in this version are:

  1. Pages sending the XHTML content type 'application/xhtml+xml' are not parsed correctly as HTML causing their links and violations to be empty.
  2. Report Analysis fails if the META tags include certain characters.
  3. <style> tag is not parsed correctly if it is empty causing Invalid Markup violations to be flagged incorrectly.
  4. Memory is not released when the "Store Copies of analyzed web pages locally" button is unchecked.
  5. HTML with leading empty lines and doctype fails to parse correctly causing their links and violations to be empty.
  6. Internal Link criteria option of "host: <sitename> and subdomains (*.<sitename>)" fails to work as expected under certain configurations.
  7. System.NullReferenceException when content attribute is misisng in Meta tag
  8. Windows authentication does not work with servers configured with NTLM or Kerberos only challenge.
  9. External META tags are stored in the report making it cumbersome to use the important ones.
  10. Several localization related bugs.
  11. DTD error when navigating to the Sitemap and Sitemap Index User Interface.
  12. And others…

This release is compatible with v1.0 RTM and it will upgrade if already installed. So go ahead and install the new version using Web Platform Installed by clicking:

    Please make sure to install the latest version, this shoudl be fixed in the latest version. Could you check the registry key:


    You should have a Version number there that is at least:   7.1.731.0

    This is the refresh release, if you have 7.1.672.0 or smaller then you are running the RTW or less which includes that issue.

    In my HKEY_LOCAL_MACHINESOFTWAREMicrosoftIIS ExtensionsIISSEO I have version 7.1.0731.0, the old one. But when I try to download the latest version it informs me that I allready have version 1.0.1? Do I need to reinstall IIS?
