Abstract

Methods, systems, and computer program products are provided for spell checking URLs in a resource. Embodiments include identifying within a resource a URL, determining whether the URL is valid, and marking the URL as misspelled if the URL is invalid. In typical embodiments, determining whether the URL is valid is carried out by resolving a domain name contained in the URL. Typical embodiments also include suggesting an alternative spelling for the URL. In some embodiments, suggesting an alternative spelling for the URL is carried out by identifying a keyword in the resource, querying a search engine with the identified keyword, and selecting a URL in dependence upon search results returned by the search engine.
