Google Research has announced that they will share (for an undisclosed fee) a trillion keywords with everyone. They say:
We processed 1,011,582,453,213 words of running text and are publishing the counts for all 1,146,580,664 five-word sequences that appear at least 40 times. There are 13,653,070 unique words, after discarding words that appear less than 200 times.
What would you do with such a list? Of course, the first thing that comes to mind is using it to create trillions of spam pages. But what about some more white-hat uses? How about creating a tool that generates keyword research for the selected keyword? Or a tool that presents comparison figures for a group of keywords? I'm sure there are plenty of creative ways one could use such data. Any thoughts?
