Q1. I want change the permalinks from /%category%/%postname%/ to /%postname%/ Is it good or bad? (post similar posts in my site and post many of them) how does it effect on SEO? my all B-links are lost? if yes then can i redirect? Q2. If i post content to target more keywords, does it effect already ranked keywords? I mean ranking of already indexed pages fall due to this (posting for more keywords)?
