SEO techniques can be classified into two broad categories: techniques that search engine companies recommend as part of good design ("white hat"), and those techniques of which search engines do not approve ("black hat"). The search engines attempt to minimize the effect of the latter, among them spamdexing. Industry commentators have classified these methods, and the practitioners who employ them, as either white hat SEO, or black hat SEO.[50] White hats tend to produce results that last a long time, whereas black hats anticipate that their sites may eventually be banned either temporarily or permanently once the search engines discover what they are doing.[51]
When you ask your friends which online video platform they use, the answer you probably hear the most is YouTube. YouTube is the largest video hosting platform, the second largest search platform after Google, and the third most visited website in the world. Every single day, people watch over five billion videos on YouTube. It's also free to upload your videos to YouTube and optimize them for search.
