Sohu, as a portal site, imposes various limitations on its Sogou. The spin-off of Sogou from the portal site allows it to focus on the development of search engines. With fewer constraints from the portal site, Sogou will have more room for development. However, if Sogou is to succeed in the search market, it should ensure that searches are objective, fair and neutral, and steadfastly avoid doing evil. At the same time, it should focus on user experience and provide simple and fast "one-stop service". The future development of the Internet tends to provide comprehensive services. Only in this way can it enhance user stickiness and expand user channels.
