Refers to a Google “Manual Action” where a human reviewer has determined certain pages on your site violate Google’s quality guidelines.
Exchanging money, or something else of value, for a link. If a link is purchased, it constitutes an advertisement and should be treated with a nofollow tag so that it does not pass PageRank.
Taking content from websites that you do not own and republishing it without permission on your own site.

Like “black hat,” spammy tactics are those that violate search engine quality guidelines.
Google describes unnatural links as “creating links that weren’t editorially placed or vouched for by the site’s owner on a page.” This is a violation of their guidelines and could warrant a penalty against the offending website.
