Blekko, which made a name for itself by implementing even harsher measure against low-quality content than Google, just upped the ante in search once again. It has introduced a new feature that searches for data typically difficult to find, for free, at least.
Called Web Grepper, it allows users to run searches on the entire Blekko index of more than 20 billion URLs. Such searches can pull data not found via keywords, such as the HTML coding of a web page. Blekko tested several scenarios with the tool including the number of sites utilizing Facebook Comments vs. sites using Disqus, the number of urls and domains using nofollow tags and sites with rickroll links. It also used the tool to determine which type of feed is more popular, ATOM or RSS. (via Search Engine Land).
The Current Search Engine Marketplace
Other than Bing’s encroachment on Google’s turf, little has changed in the search engine market, in terms of market share. Yahoo posted a 5% month-over-month growth rate in US core search queries during August 2011, rising from 3.44 billion to 3.61 billion core search queries, according to comScore qSearch data. Meanwhile, AOL saw its core search queries decline 9%, from 251 million to 229 million. Google ranked first with 12.5 billion searches (up 1% from 12.4 billion), followed by Yahoo, Microsoft with 2.6 billion (up 1% from 2.57 billion), Ask Network with 510 million (up 3% from 494 million), and AOL.
The 'Third' Search Engine?
Blekko, a search engine launched last year with a value-add proposition of human curation, may eventually shoulder its way into the top tier. Besides Web Grepper, it has carved out a number distinctions between it and Google and Yahoo, namely a series of updates to its user and search privacy options. It has decided to hold personal data such as a visitor's IP address, location, browser, language, date and time of visit for only 48 hours. Google and Yahoo, by contrast, keep this data for more than a year. It also has integrated with Facebook.
