Yesterday I talked about Blekko, a new search engine that's gunning for the number three spot in the search market. I covered its new approach to search involving slashtags, and explained that Blekko's registered users can create their own slashtags and even use other people's slashtags. But Blekko offers its users more than that – much more, in fact.
Each search result on Blekko features a discreet line of Blekko-specific links under the link to the item. These links, in order, are labeled tag, seo, links, cache, ip, adsense, and spam. Some of them are described in Blekko's video for new users.
Take the spam link, for example. According to Blekko CEO Rich Skrenta, if you click that link, you will never see that particular site in the search results again. It would be nice if Google did that, wouldn't it? Meanwhile, as you'd expect, the ip link gives you the IP address for that particular result. You don't even have to click that link, as hovering over it will give you the number.
It's the seo link, however, that will give you a mind-blowing result, especially if you're used to Google's secrecy. Clicking it takes you to a page that shows you the site's rank, number of inbound links, number of pages in the site, and more.
Some of this data is neatly organized under tabs, and going to these tabs can be downright eye-opening. You get a nice pie chart or two that separates the site's incoming links by US state and country. You get crawl stats for the site that tell you how recently Blekko crawled it, how many pages were crawled, the average length of the pages, and more. You can get a list of URLs for all of the pages on the site that Blekko has crawled.
The duplicate content tab really made my jaw drop. Under this tab, Blekko lists domains that duplicate content from that particular site, how many sections are duplicated, and even links to the sites that duplicated content! Do I really need to tell you how useful this can be?
