Thank you all for replying!
I'm more interested in just the search views, though. Because these are the ones that are directly affected by your SEO.
Here's an example. I had quite successful (to my mind) Valentine's sales, so last two weeks I was getting about about 25 search views a day, but that was because everyone was crazy about Valentine's day and printable cards are quite a popular option. :D
Right now, when Valentine's Day is over, I'm getting about 3-5 search views a day, which probably means that the SEO of my non-Valentine's items sucks. Or maybe that's normal.
So that's what I'm trying to understand here. I mean your overall traffic has a lot of sources, people can view your items by clicking on them from another item or from someone's favorites, or lots of other things, but search views depend mainly on your SEO, am I not right?
