There's something pretty f'ing major going on in my niche in the UK at the moment......masses and masses of new sites, mostly overseas (generally .au or .nz).
All sites that were ranking on page 1 prior to Friday for almost every term I monitor have been scattered to the four winds. Top 3 sites seem to be fairly unaffected but everyone else has been pushed down by anything from a few places to several pages.
Can't believe nobody else has mentioned it here yet. Looks like a bomb has gone off.
