What is a multi-level scheme?

Multi-level backlink scheme (tiered link scheme)

Link building is about building backlinks. Most SEO experts focus on building backlinks from sites that have already build a high value DA, PA and are likely to pass on high link juice. This can be expensive.

Another way is to create a page with a lower value backlink and link juice to this page create using the links that lead to this newly created page. In other words, you create additional links that lead to a page that just links to your site. A multi-level scheme also serves to be indexed more quickly by search engine. Search engine crawlers can access your site from multiple sites, so they will probably index it sooner. This is classic link building in nature. You just have to go deeper into the structure.
