I just read a thread where a guy said he was building 5 Web 2.0's per day, that's a lot. I was under the impression that You could just build a 1-3 and then blast lower Tiers. What am I missing here? Say I have a really low competition keyword. The top 2 site ranking in the niche does not even have the keyword on their page, not even using it in their anchor text at all. The number 1 site in Google only has 24 blog comment backlinks from the same blog, it's a PR 3. I don't have the full version of ahrefs or Majestic SEO so I can only see a few of them, but the ones that I can see are just blog comments. Stats for the #1 site below: Backlinks: 24 Referring Domains: 1 Citation Flow: 24 Trust Flow: 6 What other Tier 1 link types do you guys like best? Should social bookmarks be used?
