My question is, I've just been using a standard php header() to do the forward. But when I did a site:foo.com in google, my random script was in there and had all the content of a random widget.

Do I do a 301 permanent? If someone searches for that widget in google and goes onto the random page, they don't actually end up on the intended page, it just randomizes it again.

Should I tell google not to index it at all? I put it in forum signatures all over the web bc I figured it would randomly choose a widget everytime google looked at the page. I don't want to fudge up my serps.

Thanks!
