I ran across this today: http://www.site-reference.com/Search-Engines/7565/index.html I wouldn't want to be the CEO of webposition today..
Hrm... interesting find. Here comes the question - what about those of us using the Keyword Tool regularly (I have a cronjob that checks daily)? When they say Google queries, are they referring to the API?
I think it's those who do automated queries to google.com, not the API. The API is fine. People like webposition.com I believe did thousands (hundreds of thousands?) of queries a day.
so this could also be the reason why my favorite site where i use to check my ranking returned an NF result for google.
