Hey guys, in this months I got some penalties in my website and some keywords went down, my traffic switch from 1.000 users/day to 500 users/day. In this days I tried something, I re-write the posts for the keywords that I lost ranking and redirect the old posts to the new with 301 redirect, and now i'm seeing that my position for this keywords dance like 10->90->40->11 etc. for the new urls, I did something wrong?
