Wow, talk about strange issues with MSN Live. I just performed a search on Live.com and the 3rd and 4th results were Google AdWords ads as pictured below:
Actually, I'm not the one to have discovered this. Michael Dorausch spotted it at the Raven SEO blog. Interestingly, this was picked up yesterday and was posted to Sphinn but the problem remains. At least Google removed its raccoon problem in a timely manner. ;)
But as Barry points out at Search Engine Land, Google is blocking this kind of spidering in their robots.txt file and MSN is still crawling the information. In fact, Barry notes that they crawled over 4 million ads.
It makes you wonder what their CTR is and how Google AdWords can possibly track the CTR accurately...
