  • Abstract

    Knowledge about the general graph structure of the hyperlink graph is important for designing ranking methods for search engines. To amend the ranking calculated by search engines for different websites, search engine optimization agencies focus on linkage structure for their clients. An extreme appearance of ranking manipulation manifests in spam networks, where pages and websites publishing dubious content try to increase their ratings by setting a massive number of links to other pages and retrieve backlinks. The WDC Hyperlink Graph on first level subdomain level has been extracted from the Common Crawl 2012 web corpus and covers 95 million first level subdomains, linked by almost 2 billion connections, which are derived from the hyperlinks of the pages contained by the first level subdomains.
