So my host went dead a couple of weeks ago, and it took me a day or so to get all of my sites back up. The next time I tan the keyword checker, I got a result of 'n/a' for all my sites - and I assumed that my rankings dropped off by being down for a couple of days. Two weeks later, I'm definitely ranking #1 for a couple of keywords, but the keyword tool still shows "n/a'. I've checked to make sure the URL I'm checking is the same as Google is returning, and they are. Is there anything I can do to get up and going again short of deleting all of my entries and losing my historical data?
Turned out that the URL for the Advanced Usage Script was no longer working. I put the script onto a different server and all seems good now.
