I've analyzed the provided text and extracted the following key points:

1. Internet Information Services (IIS): A flexible, secure, and manageable web server for hosting anything on the Web.

2. Free SEO Checker 7.5: A free extension for Google Chrome that scans quickly for broken links on any given page.

3. LibreOffice Viewer App: A document viewer app for LibreOffice documents available for Android and iOS devices.

4. SEO Writing Assistant: A free tool from SEMRush that provides assistance with SEO writing, available as a premium service with additional features.

5. WordPress: A free and open-source content management system (CMS) that requires installation on a web server or locally on a computer.

Additionally, I noted the following:

* The Freelancer plan for this SEO service offers customized pricing plans for small businesses and startups, with a 14-day free trial and the ability to create up to 5 campaigns with 500 keywords.

* The premium version of the SEO Writing Assistant provides additional features, including the ability to add more main and related keywords, as well as free updates and support for a year.

I also extracted a mention of an idea to include a donation box for charity in one of their services (Typepad to WordPress migration), similar to what they have on their SEO for Firefox tool.
