I am 301'ing a site to another site, then dropping the 301 after a couple of weeks to see what happens. Both strong sites. Hard to tell changes so far other then keyword traffic for old site coming to new site. Rankings seem to have dropped but traffic is up, even a week after dropping the 301, but not for the other sites keywords. Don't think either site has penalties, only one in G analytics. In short, my rankings are not up but traffic is, following a temp. 301 redirect.
