Include has marks showing no change on CSV export
Currently, the CSV cell is left blank, and it's hard to explain whether we're just not ranking, or there was no change during that period without going back to the site.
Since the CSV is all about numbers, I've updated the CSV to fill in zeroes (rather than --) when there is no change, leaving the "no rank" slots blank. That should allow you to distinguish between the two. Thanks for the note!
