The top 500,000 keywords from the Wordtracker's database are available for £1370. Probably worth a bit more than the recent list of top AdSense words.
1/2 Million is all long tail.
What about the short tail list?
I think the data from the new free adwords keyword tool is probably causing curry for Wordtracker... hence this recent offering.
I am surprised at how little press the new AdWords tool got. Someone should issue a press release on that ;)
LOL... I had some ppl in india manually extract the top 1 million keywords more than a yr ago for $500... just took a little more time but I wasn't in a rush.
