My experience with Bing is wearing thin. But I just started. Find it odd, I had one of their team members walk me through setting up my ad. Was approved, only for a day later for them to take down the ads, saying it violated their terms of service. WTF
My experience with Bing, is that the prices are often much lower compared to Google. You can also reach other people than those who only use Google.
You can be successful using BING-Ads but you have to gain knowledge e.g. with regard to: 1-The Art of Choosing a Niche for Paid Traffic 2-How to Get The Right Keywords (includes long tail strategy) 3-Domain Purchase & Set Up (for audience demographics) 4-Lander/Optin/Thank You Pages (how to build for quality score and conversions) 5-DKI- Dynamic Keyword Insertion/ QueryString Insertion 6-Build Your "Thank You Page" 7-Find 5 Affiliate Offers 8-Add cpa-Offer to "Thank You Page" 9-Aweber / Getresponse- Set Up Summing up it may be said that using BING-Ads is not so easy as many guys tell you….
The user-base is very different at Bing. These are typically older and less technologically savvy users (as they simply keep the installed settings of their PC - which is how they wind up using Bing). There are some very good use-cases for targeting this demographic. Unfortunately, I have not much to offer these users, so, personally, it has not been particularly effective.
