Why are search results different for 'Yahoo Search' and Powered by Yahoo search?

So if you misspell something (no dns to connect with... unregistered domain as an example) on a browser that uses a Road Runner connection, it takes you to a search engine 'powered by yahoo search' which searches for whatever you typed in.

Anyway, today we noticed that the website of one of our clients isn't coming up in this 'Powered by Yahoo Search' via roadrunner but comes up in Yahoo Search for the same query. In fact, we noticed that our clients website (10 yrs + established site) is missing in yahoo powered by search but on all other engines.

Any clues? I thought this should be generally the same across Yahoo / Yahoo Powered / Bing / Bing Powered.

Could this be using something pre-bing merger?

It's kind of like like having a different set of product descriptions for your own site vs. product descriptions you provide to shopping aggregation sites.

Why would you want to give away your best, most current, stuff?  If you did, what would motivate people to go to your site?  They don't TELL people that, but that's the reality of business.

Could you clarify what you mean? Are you implying that Yahoo sponsored search is intentionally different?

I believe they are, yes.

Here's another concept.  Yahoo's own search results come from Bing.  What would be the point of Yahoo displaying the exact same results as Bing though?  So it's a known fact that Yahoo takes Bing's data and changes it for the main Yahoo search.

So in that same way, I am saying I believe Yahoo then goes even further and provides yet a different result set for "powered by Yahoo".
