What are Tier 1 and Tier 2 in Seo?

Tier 1links is directly pointed to money site. And the links that pointed to tier 1 is called as Tier 2 links. Tier 1 links are fully manual process; there is no automation tools for building links, well written contents only used for posting in High quality authority domains. Such as Niche blogs, Web 2.0s, Articles, Squidoo and Hub, Press release, etc… Also build HQ SBM and Directory listing with unique Ad-Copy for every submission. Tier 2 links are semi-automated process; we use both manual and automated tools for building links, here we use spun content for posting in micro sites and article sites and also build some amount of blog commenting, social bookmarking links with either manual or tools. These tier 2 links are backlink to Tier 1 links so that passes some authority link juice to tier 1 links. The authority and value of tier 1 links are increased automatically with the help of Tier 2 links. If the tier 1 links get more value means your money site also get more authority and value. Note: we also build tier 3 links with fully automatic process; it’s completely pointed to tier 2 links!
