I bought expired domain with real PR 3, PA/DA 20+, backlink profile looks good, around 100 backlinks, few years old domain and I've redirected it to my money site yesterday. Today, I am facing little SERP drops for almost all my keywords. Is it possible that really quality (I have checked it with many tools - it is good domain for sure) domain that is 301 redirected hurts my rankings? Or it is just drop before big positive SERP movements? I mean, is all that authority and link juice that passes to my site puts my site in "waiting period"?
