Purple Yahoo! and Search Engine UI Testing
Mystery Guest and I were running some queries on Yahoo! earlier this afternoon, when we received my personal favorite search results UI test pages, the beloved Purple Yahoo! Purple Yahoo! is a rare beast, from what I've seen. This is only the second time I can remember being served the results, though I know others have seen it before ...
7 Reasons Why Search Engines Don't Return Relevant Results 100% of the Time
While search engine representatives and light hatters (the whitest of the white hatters) say that having great, link-worthy content and links is enough to get high rankings, there are many sites with these traits that do not get listed for the words that matter (the ones that send serious traffic).

There are some days that you know that you are just too close to data to really be able to find what you are searching for. Our company just hired a director to develop the French market in Eur...
Yahoo! is Clearly Confused About My Personal Relationships
Just a short one that Mystery Guest pointed out to me in a huff tonight - Yahoo! search team, I think you owe her some apologetic flowers after this one. Her exact words after showing me this search were "do you love her?": ...
