Supplemental results in the indexing of web pages on my hosting

[Mano]

What is the name Supplemental results based on SEO? I know that this is some type of Google indexing, but I do not know anything more. I guess I could gain any advantage in the indexing of web pages on my hosting.

This type of indexation is bad. This is part of the indexing of Google, which includes pages with not enough content, pages with no unique content or pages that do not have any connection to itself. The main purpose of the index with supplemental results is to accept pages with a poor quality, so in the main index to remain quality pages with unique texts.
