Duplicate Content

The technique is relatively simple. It means copying content from another website and claiming it as your own content. It also involves copying a section from another content and not adding a direct link to the source. This practice will lead to your website being penalised by Google.

Splogs

Splogs are meaningless contents that contain a vast amount of hyperlinks. The whole content is filled with useless materials that are not worth reading. Google can de-index blogs or websites with splogs content.
