Scrape Google search results -Title, URL by Location

gistfile1.txt

function scrapeGoogle() {

  var searchResults=UrlFetchApp.fetch("https://www.google.co.uk/search?q="+encodeURIComponent("keyword finder tool")+"&num=30",{muteHttpExceptions:true});
  
  var titleExp=/<h3 class=\"r\">([\s\S]*?)<\/h3>/gi;
  var urlExpression=/<h3 class=\"r\">([\s\S]*?)\&amp\;/gi;

   
  var titleResults=searchResults.getContentText().match(titleExp);
  var urlResults=searchResults.getContentText().match(urlExpression);
 
  
  //To get the actual Title
  for(var i in titleResults)
    {
    
    
      var actualTitle=titleResults[i].replace(/(^\s+)|(\s+$)/g, "").replace(/<\/?[^>]+>/gi, "");
      Logger.log(actualTitle);
    }
    
   //To get the actual URL
  for(var i in urlResults)
    {
    
    
      var actualURL=urlResults[i].replace('<h3 class="r"><a href="/url?q=',"").replace('&amp;',"");
      Logger.log(actualURL);
    }

}

Are there special configuration of the "Google Script" that is needed before running the script? I took your script and added one line (Logger.log(searchResults)) before the closing curly brace to print the searchResults. Upon dropping the texts to an HTML file, it appears to be only the search box itself has been returned.. Thus, subsequent Regex tricks will consistently generate null results when I continue to "print", say titleResults and urlResults.
