for the last ten days every other day i have appeared on the first page for every single one of my keywords and/or combination of, the other days my pages fall off for some keywords but stay on the first page for others, is this because i'm having a tidy up of my site, updating the code but not the layout/content, does freshbot see a change in code as an update?, ok i suppose i've added a few h1's but that the only change i would normally think of it seeing.
Will i be knocked around serps until i finish updating the code?,
i'm not complaining about the increase in traffic every other day though :)
