Webring is a collection of websites linked with each other in a ring-shaped structure. For improving search engine rankings, webrings can be regard as a certain way for search engine optimization technique.

To be a part of the webring, each site need to have a common navigation bar; which contains links to the previous and next site. By clicking next (or previous) repeatedly, the user will eventually reach the site they started at; this is the origin of the term webring. However, the click-through route around the ring is usually supplemented by a central site with links to all member-sites; this prevents the ring from breaking completely if a member site goes offline.

Webrings are usually systematize around a specific theme, often educational or social. Web rings usually have a moderator who decides which pages to include in the web ring. After approval, webmasters add their pages to the ring by 'linking in' to the ring; this requires adding the necessary HTML or JavaScript to their site.

Webrings actually allows site visitors to click through and visit as many of the sites in the ring as visitor wishes.
