Links from forums and blog comment is my priority but I Also get links from article directories and press release. I still suggest different combination of link building is the best.
How about bulk links from blogspot.. i found someone offering like 1000+backlinks with very cheap price on DP. will that work? i keep wondering the answer of this question since long time ago
You'll find that the blogs are full of ads, so I think Google with devalue any link, as the theme isn't relevant to most backlinks.
if this was the case, then we all will buy a million crap back links for a competitor and get them banned wont we? most things that you can do offsite may not get you any benefits but you really have to over the top naughty to get banned by google.... if you are not playing ball . big mr G will just ignore you in my view
