I have a site that I've been developing for a little while. I saw yesterday that it had gotten #10 in the Google SERPs for Widget Store (my store name is The Widget Store, with widget mentioned frequently on the site). I checked a little later to see it had fallen to about #25, then I checked today and it was off the SERPS alltogether. I'm at a loss to explain how it went on and off the SERPs so quickly. Any ideas?
