What does this mean in real world terms?
The example I used to highlight this problem was the same for when BING first came out this Spring. I used a search for 'laboratory outsourcing'. The BING results are still showing a glaring weakness in BING's ability to filter out similar results. The first few organic results are quite good actually (especially since my webpages dominate at the top), but when you get past the 9th indexed link or so, things get very strange and repetitive, many of the pages are essentially of zero use for an individual looking for new information related to 'laboratory outsourcing'. Why? Because one company has identical or similar content present on different national domain websites. BING does not yet understand that these pages all belong to one company, or indeed that the content is similar or identical, so all these pages are listed, page after page after page after page.
I'll give BING some credit, the results are not as bad as 3 months ago... but they have more work to do. BING is very interesting, as a heavy user of Adwords campaigns I need to have a viable alternative to Google. I don't have one yet. And the new Google interface is rather 'interesting', to say the least. BING may be useful yet, if my B-to-B technical services clients start using it.
