YahooSeeker neglecting directory listed sites?

My observations - makes sense?

[adfree]

I know of two larger sites (one being my own) that are listed within Yahoo! - one of 'em grandfathered.

Both sites get a lot less hits and less frequency too from YahooSeeker than compariable sites not being listed in Yahoo!

What do make make of that? I can't come up with sense there.

Thanks, Jens

Anyone?

I don't understand the question? Does Yahoo's shopping spider give priority to sites in the directory?
