Web catalogues are collections of linked internet addresses, typically organized by specific categories like industry. They enable users to search for information in a more focused manner. Prior to the advent of search engines, web catalogues were the primary method for locating websites online. From a search engine optimization perspective, listing your site in a web catalogue can be beneficial. It not only enhances website discoverability but also provides an additional backlink, which can improve your site's credibility and search ranking.
