Okay, big shift for me today: I'm up 38% on google.com traffic. I'm ranking higher on a number of mildly popular phrases and a lot of long tail phrases. But I'm also down on a lot of other phrases, so I'm guessing this is still just Penguin shifting around.
I did delete a huge number of pages last night - about 1/3 of my content. These were pages that no longer seem relevant because the perception of my niche has shifted over the years. I should have deleted them ages ago, but I just had trouble letting all that hard work go, LOL. I seriously doubt this is why my traffic is up, though - I made this change for visitors, not SEO. From what I've heard, even if a change like this does help with SEO, it should take weeks or months to see the change in the SERPs, not overnight.
