I have been working with a few WordPress installs, 2 of which are installed as the index page and the 3rd was added to an 8 year old site in a folder. With the same plugins, etc... and it is the only one that I can't find on Google. The other two will rank for posts within minutes, but the third one I even tried searching for quoted lines and nothing...

Anyone else experience this?

Any thoughts on maybe the "why"? - I am thinking about creating a whole new site instead of adding it to a folder of the original site, but I would rather not add any more to my plate right now.
