Yahoo Panama vs. MSN adCenter
Who ever thought two venerable internet giants would be scrambling to be No. 2 in the $15 billion paid search industry? While Google is the undisputed leader in paid search 
marketing, Yahoo! and Microsoft don’t even come close.
Google’s secret weapon is continuous product improvement and fierce customer loyalty. There is no disputing the fact that once Google gained its reputation for relevancy, users have remained tenaciously loyal, despite the fact that relevancy is no longer golden. This monumental branding feat has proven hard to beat. As market share continued to rise, Google dominance became a self-fulfilling prophecy.
Now that Panama is fully functional, and adCenter has been established for more than a year, read how the two platforms compare.
