Hi, My website  is normally on page 2-3 on google consistently. Over the past month it has been appearing and then completely disappearing from the serps. One day it will be on page 2, then the next day completely missing from the serps. When i check the index it seems to be indexed correctly when doing site:mysite.com. I don't understand why this keeps happening, any experience with this issue? It doesn't seem to be a google dance as far as I can tell. When my other sites dance they typically just go up or down a few ranks for a couple weeks until they stabilize. Not completely fall off the search engine.
