Google is adding commercials to selected YouTube videos. The ads in question only appear if the user does not click on the overlay ad that appears during the video. If the ad is not clicked, the advertisement will play after the designated video has finished. Many analysts believe that the ads are Google’s way of making money on a service that is heavy of fan support but light on monetary impact. At the present moment, these so-called “post roll” ads only appear on roughly 4% of the videos uploaded.

Sometimes finding out the “vital information” to a website is as easy as clicking a mouse. While there are several organizations out there that perform this service, most just pass along “basic” information like ownership stats and general tracking information. For something a little more in depth, we suggest you try Quarkbase. Quarkbase is a veritable one-stop shop for website helpful information, including who owns it, what its Alexa stats are, how many Diggs the page has, and which sub-pages are the most popular. Easy to read and even understand, Quarkbase is the perfect program for the occasional “web 2.0 background check.”

Zoho, an India-based company best known for its popular online Office Suite, has announced the creation of its own Application Marketplace. The aptly-named Zoho Application Marketplace allows programmers create their own Zoho-compatible mini applications and release them for free. The Application Marketplace puts Zoho in direct competition with Salesforce.com’s similarly themed AppXchange service. At press time, there are over 100,000 applications available on the service.

Next, we have Zapproved. Zapproved tries to take the slow, painful process of managing a group of people a lot more simple and streamlined. Anyone that has been in meeting hell knows that getting a small group of competent people to agree on any one thing can take forever. Zapproved moves this process along, and uses the power of web 2.0 to get it done.

And to finish off the week, we have a new video from Marlon Sanders. In the new video Marketing Minute, Sanders shows how you can double your “opt in” rate on a squeeze page. For those unaware, a “squeeze page” is the page where users can conceivably subscribe to a variety of services, such as a mailing list. The video is only ten minutes long, but it covers a lot of ground and gets some great ideas rolling.
