Welcome to the Q&A Forum

I'm sure this question has been asked before but I couldn't quite find the answer I was looking for. Basically, I'm trying to understand why the inbound links I've created hardly ever show up in Webmaster Tools or Open Site Explorer, when other (relatively new) sites have hundreds of them. For example, I'm building a small niche site for which I have written all original content; some product reviews, some more general articles. Then I have rewritten the articles and posted them on popular Web2.0 sites to find human traffic as well as building authority through the links. I've linked some of the smaller sites together to form a wheel for additional authority. I've pinged the off-site articles and some of them have been indexed but the links don't show up in, even after a couple of months. I've checked the articles for duplication, just in case, and they're all 80-90% unique, or more. I've done similar things for other small sites and the links sometimes show up, but it takes 4-6 months which seems ridiculous. It's frustrating when I'm doing everything by the book (as far as I'm aware) and getting nowhere in the SERP's, while other sites have hundreds of links from spam blogs with poor quality, unrelated content and are sitting on page 1. I've also bookmarked the off-site articles and submitted the RSS feed where appropriate. My intention was to continue adding content on and off site but it just seems pointless if it never has any value. I just don't know what else I'm supposed to do. Any help or advice would be greatly appreciated. The URL of the site I'm currently working on is www.impact-wrench-reviews.com. Thanks, Tom.
