As return-on-investment (ROI) becomes more of a priority in this lean and mean economy, interest in and spending on search engine marketing (SEM) continues to grow in spite of smaller advertising budgets.  As the folks over at Search Engine Marketing Professionals Organization (SEMPO) brought to light in their most recent State of the Market Survey last March, long term projections for the industry show a total SEM spend of $26.1 billion in 2013, up from the projected $14.7 billion projected for 2009 by 77.5%.   

SEM can seem like a complex, daunting new endeavor for many business owners and marketers who are already wearing many hats in their daily lives.  If you could use some guidance around using adCenter and troubleshooting campaign issues, then the Microsoft adCenter Learning Center may be just what you're looking for; it's virtually a one-stop show for all things related to adCenter help.  In addition to videos, webcasts and case studies, you'll also find quick links to some of the most commonly sought-after information along the left hand navigation:

If online tutorials that walk you step-by-step through adCenter's features sounds appealing, then I would highly recommend checking the final link along that list, Microsoft adExcellence:

AdEx

Not only can you get all the adCenter help you need at a pace and schedule that's comfortable for you, all the adExcellence classroom trainings are completely free of charge. 

If you'd like to take the adExcellence Exam to become an accredited Microsoft adExcellence Member, there's a $50 fee for each exam attempt.  It's not necessary for you to take the exam if you just want to go through the trainings, but if you're an SEM professional or agency representative, having the official logo to add to your e-mail signature and a listing in the adExcellence Member Directory can be helpful in providing your clients with the peace-of-mind and confidence in knowing you're certified to handle their SEM campaigns on adCenter.
