Track keywords in Ruby on Rails using Google API

Below is essential part of code which tracks ranks of keywords in Google. As almost always in Ruby world, this source code is self-explanatory. It was partially inspired by this Bernard Peh's article. If you are PHP developer and willing to become programming language polyglot, compare length of relevant code and its readablity. If you think this snippet sucks in any way, comment on! Some variables in the code are defined outside of its scope, but it's not hard to find which.

Bonus tip: Ruby SOAP translates Google API field URL from resultElement structure to method uRL!

  def update_link_rank(iterations = 10)
    # sanity chceck
    iterations = 10 if iterations < 1 || iterations > 100
    
    require 'soap/wsdlDriver'

    begin
      driver = SOAP::WSDLDriverFactory.
new("http://api.google.com/GoogleSearch.wsdl").create_rpc_driver
    rescue
      puts "Error creating rpc driver: " + $!
      return
    end

    for i in (0...iterations) do
      begin
        result = driver.doGoogleSearch(
user.google_api_key, anchor, 0 + i, 10 + i, true, "", false, "", "", "")
      rescue SOAP::FaultError
        puts "Got Fault: " + $!
        return
      end
      
      partial_rank = 0
      for resultElement in result.resultElements do
        partial_rank += 1
        if resultElement.uRL.include? href then
          value = i * 10 + partial_rank
          rank = LinkRank.new
          rank.link = self
          rank.value = value
          rank.save
          return value
        end
      end

      # shorter than 10 means no next result
      return if result.resultElements.size < 10 
    end
  end
