Blekko is a search engine (in beta at the moment) that claims that it is a better way to search the web by using slashtags. Slashtags search only the sites you want and cut out the spam sites. e.g. if you only want to search for tech related stuff you put /tech after your query
The slashtags are user generated and can be either private or public. There are already hundreds of them, but you can also create your own.
But the CEO explains it a bit better in this video:
Another cool feature is the SEO link that you get with every single result
It gives you quite a substantial amount of information about your site, like inbound links, hostrank, crawl stats, site pages, you can compare your site to other sites and it tells you about duplicate content
There is also a SPAM link next to all your search result and you can get rid of searches you don’t want permanently – that search result will be dead to you.
Another interesting feature is the visualizing feature – here you can compare up to 4 different URLs with each other
Definitely a great idea and even though there are still some shortcomings blekko will be someone to watch out for. It is going to be big.
