The document discusses various link building techniques to help optimize a website and build a diverse backlink profile. It recommends identifying high and low page rank sites from different categories like directories, blogs, and press releases to get both dofollowed and nofollowed text and image links with varying anchor text. Specific techniques include providing free content to other sites, purchasing existing high-quality content and redirecting it, sponsoring relevant events for permanent links, and asking bloggers to review products without explicitly asking for links. The overall recommendation is to continue using traditional methods alongside these new techniques.
