The long awaited Ask.com Blog Search Engine has finally launched. There are two iterations: One for Ask.com in the form of another right side option. The other within Bloglines.com. The Ask.com blogs and feeds search is directed more towards general users. The Bloglines versions offers more advanced options for “prosumers” as Kaushal Kurapati from Ask.com called them in our preview call.
Key features include the use of Ask.com “expert rank” which breaks the web into communities and defines subject specific link popularity. This is combined with Bloglines.com subscription data to determine relevance in blog and feed search results.
Another key feature is the quality of content. Ask.com Blogs and Feeds search is available in 20 languages with 4-6 million articles indexed per day. There are 1.5 billion articles indexed overall. Blogs and feeds that are indexed only include the feeds that Bloglines users have subscribed to.
