Since afternoon Twitter has been buzzing with tweets regarding a possible Google search ranking update. The update has been said to have started last night. It could be a possible August 1st update. Google is yet to confirm anything on the matter.
Danny Sullivan has said they will pre-announce if any core update takes place. But, let’s not forget the last August 1st update that took place on August 1st, 2018 was also not pre-announced. Though, this update does not currently seem as big as the previous one.
