Google is not Google because yes, its Panda algorithm detects when and where an article has been plagiarized, but it will not put those blogs that write the article first, but the one that has posted it and has a greater domain.

You must take care that your texts, in addition to being attractive and effective in Google, are original, so you must be aware of not committing self-plagiarism.

There are two types of crime in plagiarism:

  • Conscious Plagiarism
