I can tell you that domain parking still exists, but its relevance and effectiveness have diminished in recent years. Domain parking involves registering a domain name and then placing a simple webpage on it, usually with ads or links to other sites, in order to generate revenue from traffic to the domain. However, with the increasing sophistication of search engine algorithms and changes in online advertising practices, domain parking has become less profitable and is often seen as a spammy or low-quality tactic. Many domain registrars and hosting companies now offer other services, such as website builders or domain auction platforms, as alternatives to domain parking.
