I've been reading and reading, and am looking for the best way to build backlinks to an aged domain. I've got a wordpress blog, 4 years old, PR1. 155 backlinks according to google webmaster tools. 365 backlinks according to bing webmaster tools. I'm not ranking very well for my primary keywords, and I'm only getting ~200 unique users per day to the blog. I'm doing some white/grayhat linkbuilding currently, by creating profiles on forums, and linking to my blog with my "website" in the profile. But I'm not getting targeted "keyword" linking with my keyword in the title or the link. Any suggestions for other methods to build my links, white/gray/black? Oh, and this is an adult (porn) blog as well. It's doing the occasional sale, I just want to get the traffic from 200 uniques (mostly blog directory traffic) to 1000-1500 uniques per day (mostly search traffic).
