Blekko
The newest search engine in town, Blekko sells itself on the richness of the data it ofers. If you
type in a domain name followed by /seo , you'll receive a page of statistics on that URL ( Fig-
ure 1-1 ) .

Blekko is also very keen on developers accessing its data, so it ofers an easy-to-use API through
the /json slash tag, which returns a JSON object instead of HTML:
http://blekko.com/?q=cure+for+headaches+/json+/ps=100&auth=<APIKEY>&ft=&p=1
To obtain an API key, email [e-mail] . The terms of service are available at ht-
tps://blekko.com/ws/+/terms , and while they're somewhat restrictive, they are lexible in prac-
tice:

Currently, the /seo results aren't available through the JSON interface, so you have to scrape the
HTML to obtain them. There's a demonstration of that at https://github.com/petewarden/pager-
