Reading 'Index Status' graph in Google Webmaster tools
- by sam
I recently found a bunch of old files that had been ftp'ed to a live production server by mistake on a static (html / css / js) site.
I manually deleted these files, but today when checking in Google Webmaster tools i found this graph below. The 'update' marker is from 3/9/14, what i can work out is what Google is trying to tell me, are they saying that :
There was a ranking update like Penguin or Panda and they penalized my site and un-indexed a load of pages which they thought were junk..
OR
Is this showing that I updated the site by deleting the files on the server on 3/9/14
OR
Is this something else ?
