Focusing on the sites that have moved up is a red herring. For this approach to have any meaning, all five sites which were below yours would have had to have had superior factors --or to have implemented those factors-- which caused them to suddenly outrank your site -- all simultaneously, and all to the same degree (since their order did not change). Even cursory statistical analysis suggest that this is extremely unlikely.
