Wikiseek was granted permission by the Wikimedia Foundation to index the Wikipedia website.[2] Wikiseek has made financial contributions to the Wikimedia Foundation,[2] and the group-edited blog, TechCrunch reported that it was donating the "majority" of advertising revenue.[1]
Wikipedia pages were re-indexed whenever Wikipedia had a database clean-up; external links were re-indexed weekly.[2] Search results included tag clouds of Wikipedia categories that contained the search term.[1] The first three results of any search would always be Wikipedia articles, and the remainder were a mix of Wikipedia content and websites linked to from Wikipedia.[1] The service used user feedback to reduce the likelihood of spam.[3]
TechCrunch commented that the search engine may cause confusion with the Wikiasearch engine that had been announced the month previous to Wikiseek's launch.[1]
