Pyramid backlink is one of the strategies that generate high-quality backlinks to your site, strengthens those high-quality links and improves the index rate of those backlinks. The backlink is easy to implement, easy to explain and useful in many ways. For preventing penalties, this strategy is made with tire backlinks. Like Tier 1 is a quality website which is pointing to your main website, Tier 2 points to your Tier 1 website. After that Tire 3 created a pointing link to Tier 2 website. Pattern as example:
Tier 1 : 10 (guest post + article submission) backlinks
Tier 2 : 30 (social profile creation + web 2.0 + classified ad posting) backlinks
Tier 3 : 60 (blog comment + forum backlinks + social bookmarking + directory submission + PDF submission ) backlinks
