HotBot is one of the few engines still offering a free search engine listing. The first link below is about the last place available to submit to the Inktomi database at no cost.

Be aware that registration is required to use the free search engine registration service but Lycos/Hotbot offer no guarantees as to the effectiveness of using their free listing service.

HotBot, now owned by Lycos, is another once popular search engine that has lost many of its followers over the past several years. However this service has made changes of late and is working hard at a comeback.
