I have noticed that the Organic Search keyword numbers are fluctuating. I went in and manually captured how many terms a page ranks for on a certain date. Then I came back a month later and the page does not rank for that many keywords on that date in the site explorer. It fluctuates just about every month. It would be nice to have a reason why this is happening. I was trying to base some of our testing on these numbers, but they fluctuate too much.
