All but one of my EMDs have been closed down and migrated to other sites with success at the moment.
The remaining one, no suitable site to migrate it to, has begun a recovery over the last month. Not all pages have recovered by any means (the majority are buried so deep in the serps that it is unbelievable) but some pages have recovered. They seem to be "index" type pages.
I am studying this to see what is the reason for the partial recovery but there is some seriously weird indexing by G in the SERPS for some pages.
