 ### Backlinks
 
 Backlinks are the result of doing a search with a query like "link:www.google.com". The number of returned results indicates how many sites point to that url.
 
     PageRankr.backlinks('www.google.com', :google, :bing) #=> {:google=>161000, :bing=>208000000}
     PageRankr.backlinks('www.google.com', :yahoo)         #=> {:yahoo=>256300062}
-    
+
 If you don't specify a search engine, then all of them are used.
 
     # this
-    PageRankr.backlinks('www.google.com') 
-        #=> {:google=>23000, :bing=>215000000, :yahoo=>250522337, :altavista=>137000000, :alltheweb=>74500000, :alexa=>727036}

     # is equivalent to
     PageRankr.backlinks('www.google.com', :google, :bing, :yahoo, :altavista, :alltheweb, :alexa)
-        #=> {:google=>23000, :bing=>215000000, :yahoo=>250522337, :altavista=>137000000, :alltheweb=>74500000, :alexa=>727036}

 You can also use the alias `backlink` instead of `backlinks`.
 Valid search engines are: `:google, :bing, :yahoo, :altavista, :alltheweb, :alexa`. To get this list you can do:
 
     PageRankr.backlink_trackers #=> [:alexa, :alltheweb, :altavista, :bing, :google, :yahoo]
 
 ### Ranks
 
-    PageRankr.ranks('www.google.com', :alexa, :google) #=> {:alexa=>1, :google=>10}
-    
+    PageRankr.ranks('www.google.com', :alexa, :google) #=> {:alexa=>{:us=>1, :global=>1}, :google=>10}
+
     # this also gives the same result
-    PageRankr.ranks('www.google.com')                  #=> {:alexa=>1, :google=>10}
+    PageRankr.ranks('www.google.com')                  #=> {:alexa=>{:us=>1, :global=>1}, :google=>10}
 
 You can also use the alias `rank` instead of `ranks`.
 There are two valid rank trackers supported: `:alexa, :google`. To get this you can do:
 
     PageRankr.rank_trackers #=> [:alexa, :google]

 ## Note on Patches/Pull Requests
- 
+
 * Fork the project.
 * Make your feature addition or bug fix.
 * Add tests for it. This is important so I don't break it in a
   future version unintentionally.
 * Commit, do not mess with rakefile, version, or history.
   (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
 * Send me a pull request. Bonus points for topic branches.
