blekko is a search engine that sorts out spam, content farms and malware by crawling a subset of about 3 billion pages. To improve search results, blekko uses a tool called a slashtag that organizes websites into specific topics.
A slashtag allows for the creation of a custom search engine. It is used to filter search results and helps users to search only high quality sites, without spam or content farms. Slashtags contain a list of websites so that when users search with a slashtag, they only search those sites.
The blekko API lets developers integrate their application or web sites in order to run searches on blekko, and to manipulate slashtags. The API also provides access to SEO information. Developers should contact firstname.lastname@example.org for documentation.
