Just got hit with a mass de-indexing of almost all my sites from the big G. Seems to be hitting blogs across the board over the last few days, BH and WH. Trying to understand what all of our deindexed blogs and sites have in common. Could it be SB, WP Plugins, certain footprints, bad backlinks...? And what the heck is up with this ?SegSt? search term from the Yandex engine hitting blogs. Some really weird stuff going on with the search engines this week. Anyone have any detailed insight or resolution from recent experience.
