I was having this debate at another forum. (forgive me)
My space weather section just could not get past 10th, searching Google: Space Weather Forecast.
Everyone said it would kill the search results since the site section has been up for 5 years as a directory. Logic just told me it should help.
I moved the whole Space Weather directory to a sub domain. In 4 days it is now second, just behind spaceweather.com
Now I know ~smiles~
