Congrats on all the views! There are a few ways you can try to figure out if you've been on the FP.
First, if you have hits on a particular item, check the treasuries including that item. Sometimes people comment on the treasury saying things like, "congrats on the FP" or something like that.
Second, check your shop stats to see where the traffic is coming from. Sometimes "other" will show up and this includes traffic from being featured in a browse category.
If that doesn't work, you can try Craftcult.com. They archive each FP with a screenshot. However, I find them slightly less reliable. For example, I've been on the FP from a treasury but no record of it can be found on Craftcult. So just because it might not show up there, doesn't mean you haven't been on the FP.
Good luck to you!
