I've been trying to rank for 5 different long tail key word phrases, I had 3 on the front page one on the 2nd page and one on the 3rd. I get home and my page had no conversions. I look up my SERP and I have moved to spots: 172, 332, 370....WTF. I look up my backlinks and they have swelled from 74 to 549, mostly from 2 blogs. Obviously this has caused my drop. The blacklinks show these two blogs over and over for various pages within the blog. Should I continue to create links, write articles, etc - or should I leave it alone for awhile. Any advice would be great because I used the same 2 blogs to back link 4 more sites that will inevitably fall to the same fate.
