I have something similar in my portfolio: http://codecanyon.net/item/jquery-image-gallery-slideshow-with-music/276301
Sales are pretty low for me as well especially this month. Last month is my best but the sales in this month drop significantly. Do the sales usually drop in this period of time?
No, they dont.
For the last year since I built my codecanyon files and been keeping them freshly updates on a regular basis, my sales have always been consistent and steady even in the slower months (like December), but this month is really bad, sales are almost 30% lower than usual, and it has been that way since the beginning of the month.
I best guess is this is the result of the ratings change plus something wrong with the search as well, since the traffic has gone down as well.
Congrats, your files are awesome!
I would give back all my Envato earnings if I could be 18 and go to college again, trust me
Even many top selling files have a lot of 1 star rating, which cant be good for authors. Introducing comments for ratings is a good idea, but this would needed to be moderated a well, because whats the point of stylesheet is missing, not a wordpress plugin comments if they are invalid.
We need the current comments system we have converted into some kind of forum type system, including all the comments made so far converted into forum threads, and all that being searchable and sortable in any possible way, thats what we need.
