Change in Yahoo algorithm?

[dave83]

I have started to notice a major change in some results in Yahoo over the past week..

search for the term 'window blinds' without the hyphens. I have a customer who has been first or second in the rankings for that term for almost a year.. as of late last week, the entire top 20 changed and my client is now 200+ in the rankings..

What do all the new top 20 sites have in common? Not one is using a domain with hyphens.. my clients site did have hyphens in the name but it was his real business name..

I'm not seeing this on the majority of searches but it is very unusual to see all non hyphenated domains in the top 20 for a fairly common term..

Anyone else seeing similar results?

Sorry Dave.....I personally haven't seen any conclusive evidence on this. Most of the domains that I see in the top 20 for directory searches are non-hyphenated.....with a few slipping in here and there.
