but since the Google traffic increased, some rankings must have improved, unless all of the increase is from long-tail.
I'm not so sure. I'm carefully monitoring a site that's slowly lost Google traffic over the past year. It's partly user behavior (that Google isn't where my audience is finding my topic, and also that mobile's getting bigger and my audience uses it... very differently for search, I'm still trying to parse this). I can't find any long tail changes that would account for my ups and downs. I think it's just that being #1 in Google ain't what it used to be on some topics.
