Just a quick pointer to this brief BuyerZone case study on Microsoft.com. For years (more like 2003 than 2006 as it says in the case study) BuyerZone has run paid SEM campaigns on many search engines, major and otherwise. Suffice it to say that we’ve gotten pretty good at it — and we can solidly recommend that if you’re a search engine marketer, you should consider adding Bing to your efforts.

With the launch of Bing, we’ve seen some great results. As quoted in the press release:

• Conversion rates are up 35 percent.
• ROAS are up nearly 30 percent.
• Spend is down 33 percent.

If there’s interest, I’ll try to share more SEM tips or strategies soon. Let me know what would be helpful in the comments.
