Ok wanted to see what would happen. Took a brand new site that I want to use down the road, nice wordpress theme, and about 16 plr articles. Did minimal link building, a little No hands seo is all -- just to bookmark it. Same linkbuiilding was done on another site same time to rule out any effects from that. Site ran well for first 2 months then WHAM disappeared from google rankings! Site started showing page 3, made it to 25 then dropped like a rock to 100 and past. Site:domainname still shows all pages indexed! In Bing and Yahoo, no penalty, currently 17, 25 and 52 for different keywords! Have replaced most of the plr content with 100% uniques quality, want to see what happens next. has about 5 PLR articles left. Will give it a month, see if it recovers in Google, then replace all content and see what happens! So far the moral is == REWRITE CONTENT or GET SLAPPED!!! Hope this helps a few folks understand the need for rewriting all articles!
