The two methodologies of "white hat & black hats" in seo coined. These techniques are classified by some categories and see in your search engine results.
black hat techniques involve trying to use trickery and deception to sway organic results in search, white hat techniques involve using the correct techniques and tools to rank your sites effectively and legally!
Black hat technique uses text that is hidden, either as text colored similar to the background, in an invisible div, or positioned off screen. Another method gives a different page depending on whether the page is being requested by a human visitor or a search engine, a technique known as cloaking. Search engines may penalize sites they discover using black hat methods, either by reducing their rankings or eliminating their listings from their databases altogether. Such penalties can be applied either automatically by the search engines' algorithms, or by a manual site review. One infamous example was the February 2006 Google removal of both BMW Germany and Ricoh Germany for use of deceptive practices. White hat SEO is not just about following guidelines, but is about ensuring that the content a search engine indexes and subsequently ranks is the same content a user will see.
Black hat techniques are illegal methods used by webmasters for getting high ranks in search engine result pages.. E.g: Spamming your posts with keywords, stuffing keywords by matching the background colour of the site (so that it doesn't irritate readers, but gains you high rank on SEs for that keyword). White hat techniques are the legal ways of doing SEO in search engine point of view E.g: Relevant link building, code Seo, meta tag optimizaation, etc
