SEO in any search engine

SEO is search engine optimization, and it’s mostly used in Google. Of course, Google is the best search engine in the world, so it’s only natural that it’s used in Google, but you can use the word SEO in any search engine, even if it’s not Google. The part that can enjoy the marketing effect through SEO is that you can see the increase in sales by exposing it to the top of the search, and the site exposed to the top of the search through SEO is a textbook of marketing that can produce high efficiency with little cost because it costs little maintenance. However, as a disadvantage, it takes a long time and costs a lot of money to raise, and no one knows for sure. It is something that Google has not disclosed, so only Google will know.
