The whois shows this as an official MS site, but strangely it is hosted on a 1&1 server not on the usual MS network.
From the IE Addons site: "The add-ons available here have been carefully screened by Microsoft".
Approved addons include:
Alexa Booster has been designed to simulate real online visitors and also simulating referrals to your site. It will improve your Alexa and search engine rankings. The Alexa Booster software will boost your Alexa rankings but it will also help increase your Google listings as well. To sum it up, the Alexa Booster is aimed at increasing your online business. Version 3.2 features a built-in referral system with a wizard and a built-in scanner.
Or even better:
Doorway Page Wizard guides you through a step by step process to create highly optimized doorway pages for your website. Doorway pages contain keywords and Meta-Tags that describe your website and are optimized to the search parameters of leading engines. They help improving ranking in search engines. Each Doorway page is specially tuned to a particular keyword search. This is a proven and effective way to increase traffic to your Web site. Doorway Page Wizard can create hundreds of doorway pages in a matter of minutes, a task if manually done will take many hours if not days to complete and a lot of hard work.
So Microsoft are now actively promoting and selling doorway-page creation tools, Alexa-boosters, etc.
Anything for a buck, eh?
Thanks to an anonymous TW tipster for the laugh.
