How does Bing Advertising compare to Google?

Did you ask about the free or low cost method to start using Bing? Are you asking about training material on how to use Bing?

It is a fairly simple interface and very similar in nature to Adwords. In general, the competition is a bit less, but in terms of ROI, Adwords will get 90% more traffic, so I recommend focusing the time and energy on the platform that has the highest availability to scale. If you have a very low advertising budget of less than a large one, Bing is not a bad way to start.

Feel free to ask Bing specific questions and I can probably answer them for you.
