Hi, got a blog downgraded from PR3 to PR1 Tell me if any of these can be the guilty ones; A) 1 MONTH AGO *- blasted 1,5k with SB directly to my blog, using the same email always (usually I don't, but for this campaign I needed to be contacted if necesary) B) 5 MONTHS AGO *- duplicated internal content (deep pages containing = article as home) C) 6 MONTHS AGO *- Did several SB blasts and later did not continue link velocity (these blasts took the blog from PR2 to PR3..) What are commons reasons for PR downgrade ? Thanks
