Howdy fellow SEO/M’s! I think I’ve noticed some pretty significant changes with Yahoo over the past few weeks, and even more so over the past few hours.

Here’s what I’ve noticed:

1. It appears PI (paid inclusion) feeds have been completely nuked from the SERPs–at least in our industry. Via our PI feed, we enjoyed hundreds of Top 3 rankings for over 3 years; now gone
2. I’m seeing sub-listings for some of my industry’s keywords, which I can’t honestly remember seeing prior to today.

Is anybody else experiencing anything like this, or worse?
