I have 2 month old (actually, new) domain and website and I have built more than 1000 high quality PR1-PR6 SAPE links since then. I reached positions around 12 and 35 for almost all 20 keywords I wanted to rank for. Problem is that I have been building only SAPE links without any other backlinks. I guess very weak link diversity is the main reason why I am stuck on Page 2/3/4 for almost last 30 days. I started building Web 2.0s, but can someone give me advice please what else to do to break the SERPs and reach TOP 5 positions on Google. I'm in medium competitive niche. I bought a service that builds 100 Web 2.0s, 100 Articles, 100 social bookmarks, and profile submissions, social signals, EDU, GOV links + 1000s of lower quality Wikis, Web 2.0s, Forum Profiles and Blog Comments as Tier 2. Is that good?
