According to keyword revealer my hardest keyword is a 15 which is VERY LOW according to them. My main keyword has 1k searches and it's only an 8 top 10 are all forum posts with 3 backlinks max from shitty sources, 9 links out of 10 in first page have 0 backlinks. My website has 16 articles and the one trying to rank for this keyword is over 1 month old, has 550 words, ~0.8% keyword density, when I first posted it I shared it on facebook , twitter, google + and bookmarked it on stumbleupon and linkedin. 3 weeks later I sent 6 expired tumblrs with minimum PA of 28 and maximum PA of 34 with clean backlink profile and decent backlinks in each of them + 5 links from the forums ranking in top 10, which means contextual backlinks although 4 of those 5 forums are nofollow. Still only ranking in #16 even though the forums have no links to the actual URL, no social shares no bookmarks no backlinks + most of them are linking to me.
