Blekko – a new day in search

Blekko is a ‘vertical search engine’, meaning that it allows you to search within a specific segment of online content, such as legal, political, media and travel. In contrast, Google is considered a ‘horizontal search engine’. The major difference between the two is that a horizontal or general search engine will index large portions of the web using their various trawlers, whereas vertical search engines only index pages that are seen as relevant to a pre-defined set of topics.
