For my relatively new sites I've found all of the big three to be totally erratic, up on one while almost unfindable on another. Just basic seo no tweaking, some directory submits. First on page one (ok sometimes that's a given for new submits) then falls to page 7-10, then grinds its way back up to vanish again, only can found within a quotation marks title search, then back to the top ten for a day or two, then only found by a full domain search, then only the privacy page is being found for the title search in quotes in google while in 2nd position on bing third page on yahoo. Totally weird.
