Microsoft adCenter

Microsoft adCenter provides plenty of information for the new advertiser. In fact, there's so much help available that you can get swamped working through it.

It includes all the features you'd expect in a major pay per click search engine. The interface is clean and very user friendly.

Setting up a new a campaign is easy, and AdCenter gives you a full range of options. There is a god keyword research tool which allows gives you the past month's searches on your chosen term and other relevant keywords and also gives you the current month's traffic for those keywords. This keyword tool also allows you to display each keyword in charts showing trends on time of traffic, gender, lifestyle and geotargeted information. Be careful! I had so much fun playing with the charts that I almost forgot I was supposed to be working.

Microsoft adCenter provides several options to help you improve ad exposure. If you want to increase the chance that a certain segment of your audience will be shown your ad, you can adjust these variables:

Geographical location
Day of the week
Time of day (morning, afternoon, or night)
Age and gender
The reporting features are very good, and you're able to obtain reports based on a number of different variables.

Microsoft adCenter provides a number of specific campaign pricing options, including base bid (The lowest bid amount that you define for a specific match type. All advanced bidding is in addition to the base bid.), cost per click (a pricing plan in which charges accrue only as the advertiser's ads are clicked. The cost-per-click rate is predetermined by negotiations between the advertiser and MSN.; average position (A paid ad's placement on the search results page. For example, the top spot on the page is called position 1. This and all other positions are determined by the ad's rank, which in turn is determined by relevance.); and monthly spend (The amount of funds expended during a specific period.). Overall, undoubtedly Microsoft adCenter is going to be a very important pay per click search engine. There are still a few bugs to be ironed out, but with a new product like this that's only to be expected.(from http://www.payperclicksearchengines.com/directory/top-10-ppc-search-engines/google-adwords-l252.html) .
