This should give a general idea of how the comics have been doing since it began to now. For the record, these don't count issues bought in the months after the initial release. (I.E. a July issue bought in October)
I would assume that variants are included in sales.
Rankings indicate how well they're doing in comparision to the other titles released that month. So one issue can have a higher ranking than a later month's, but still do worse. For example, the final issue of The Fall of Gilead had a higher sales ranking than the previous one, but still had fewer issues sold.
I'll be editing this post as updates occur.
