I know it is not the perfect time  of year to judge but lately I only sale really old files of mine.I was wondering if they changed the best match algorithm somehow?  Any ideas?it that's so I am quite disappointed as I notice a certain decrease in sales but then again may be I should wait and see what will happen after holiday season

Thanks for your input in advance

We're in the holiday dead zone up until new years.

I keep track of my image placement and everything is where it normally is. So for me, no, nothing has changed.

For me it has been quite the opposite. I see a lot of 1's in the dls column on my latest pages.
