Blekko data comes directly from the blekko search index, whereas the other tools available do not have search technology, ranking algorithms or relevance criteria driving decisions around individual searches or as it pertains to a particular data set.

You will see some similar data sets (e.g. Inbound links). However you also now have access to some information unique to blekko like the Report Card, Sections, and categorized inbound links.

As if that weren’t enough, you can run this for any site on the web! This enables you to see exactly where your competition is getting its traffic and who you might want to target with marketing campaigns.
