Shawn - there is some problem with the tracker - im trying to add keywords and its not accepting them.
It's working fine for me too. I think it queries Google with the API key before adding the kw to the db and if you've exhausted your 1000 queries/day limit then it does not adds them to the db.
Actually, now that I think about it, even if you are over the limit, it still should add it, and simply return an error saying you are over the limit so it can't actually give you a number. But the last few days the API in general has seemed a little sluggish at times. Maybe the keyword tracker is making too many queries to Google and it's taking the server down by itself. Hehe just kidding.
