Good stuff!
I close my store at least once a year for a "summer holiday"- every time I reopen it, I also have a burst of sales. I believe the exposure algorithm favors material from a reopened store for a short time, I think for a day or so.
I had to close my store for two days a couple weeks ago and when i reopened it, again I saw a brief burst of sales.....
Normally the stuff that is selling is "old" stuff, so closing/reopening a store is another way to get exposure for "old" stuff.
(by "close" I mean the items are hidden from buyers)
I did do an experiment a couple years ago just closing the store for a couple hours or so and reopening. At that time the effects of a very short closure weren't significant. I haven't repeated the experiment since, certainly closure for a couple days works, however at least in my world, the "burst" in sales wasn't any more than would have naturally happened in those 2 days anyway, and depending on how repeat customers search your material "0 items" isn't a great way to keep them thinking you are still in business, or it at least confuses them.
