Friend of mine asked me why her site would be listed on MSN but not Yahoo and Google. Her site redirects to a different domain but it uses Response.Redirect which I think is the wrong kind. (Any ASP heads know the answer to that one?)

The new site is listed in all engines but the old one is only listed in MSN. I'd put the URL right here but she would, um, what's a polite way to say this? My friend might forcibly sterilize me if I did that. She wanted to pick my brain in private, but doesn't want the world to know she doesn't know everthing about everything.

My theory is the real search engines saw a site that's not available and after a certain amount of time took it out of the list. Does that make sense? Is that how they operate? And if so, is MSN really that far behind?

I don't know the actual answer to your question.

I do know from experience that the msn bot digs a little deeper and may not be quite as strict. I have a small directory that is not seo friendly. MSN spiders and indexs most of it. Yahoo and google list the index page of the directory if I am lucky.

My point is that their spider may work like their browser, it is idiot friendly. In the interest of your man-berries, you may want to reword that if you share it with your friend.

Links would be the key to getting attention from Google & Yahoo!

MSN isn't as link driven as the other two.

it also treats 302 redirects (which is what a response.redirect will give) somewhat differently.

What u said was true in the past...
20days back MSN updated its algo and now every thing is fine...
It must have indexed now... if not ur link structure has some errors
