There is definitely something very big happened on 27th, usual traffic is 33k, I got 25k on 27th, then traffic resumed to 34k on 28th, then again on 29th it is 26k and 25k on 30th, I hope it does not go down any further, does anyone have any update?
I think it is to do with the outbound link penalties being applied to sites world wide.
Many blogs and sites are being forced to nofollow outbound links on their blogs to get manual outbound links penalties revoked.
This may not affect your sites directly, but I would guess that somewhere down the chain of links, many sites are being devalued as page rank and link value is removed, giving the impression of an algo change.
I thnik that they have a Problem with multiple listings from one Domain again ( Domain crowding ? ). Some queries return five! sub pages from our Domain in a row! Not to mention that following sites get pushed down.
I've seen a few sites lose rankings, might be temporary but something is definitely up. Also if someone has access to SearchMetrics (it's free), check out their winners and losers lists (it updated yesterday). Massive drops in their losers list
