As the name suggests, it refers to the practice of creating “copy and paste” content across domains, meaning that blocks of content copied from different sources match each other exactly or are very similar.

Duplicate content not only affects different domains, but also a domain.Article spinning is a technique similar to the problem of duplicate content (above) and is becoming increasingly popular.

This is because it is the same anchor text that is used for pages that link to that particular page.Content concealment is another black hat tactic that should be avoided at all costs.
If the title or headline of your article has to do, for example, with how to add investments in gold or silver to your retirement savings account, don't trick them into having the content address an unrelated topic, such as stock market investment. Attacking the bait with your readers is called “content concealment” and can result in a serious penalty for your domain.It's important to remember that no one knows for sure what keyword density Google's PageRank algorithm favors the most, many SEO professionals suggest that between 1 and 2% of their article consists of the keyword they're trying to rank for.
