Be prepared for this SEO interview question as well. White-hat SEO is a type of SEO that follows the guidelines of search engines. It doesn’t involve the manipulation of search engines to rank higher, or deploying questionable methods.
Black-hat SEO violates search engine guidelines and manipulates search engines to improve their ranking on the search engines. If a website is found guilty of keyword stuffing, cloaking, link exchange, link farming, PBN, buying links, link hiding, using doorway or gateway pages, etc., then it gets penalized.
