Those websites made it through the beginning of the month without losing traffic!

We actually had a 10% increase in traffic around the MayDay event then a 70% drop on 17th May.

@tedster do you think the May 17 is an adjustment completing the MayDay change?

What we have found is that a vast number of our pages (that used to rank and get traffic) have disappeared from the index altogether, leaving secondary related pages which rank much much lower (e.g. long article with 10 pages, page 1 disappears, leaving page 8 appearing in SERPS on page 20).

So what I don't understand is if there is an algo change that means google dislikes some of our pages enough to drop them completely from the index, why would they keep the other pages that rank worse?
