Automating Maintenance Tasks With AdWords Scripting Part 1

I'm not ashamed.  I read "for Dummies" books.  And one of my favorites is AdWords for Dummies. Say what you want about these books, but they are easy to read and have great info for getting started quickly.

One of the chapters in the book describes a monthly routine for maintaining your AdWords account.  Using AdWords scripts is a good way to automate these tasks.  Let's start with the first of the month.

"On the first day of the month, deal with all the keywords that are converting too expensively."

Sounds simple enough.  Of course, you will need to have set up conversion tracking for all of this to work. They say pull the last 30 days, which is what we have done here, but you can pull any time range you like.  This follows the example from the book.  You should of course replace the values at the top with ones that make sense for your business.

// Reduce Bids on High Cost per Conversion Keywords
// Created By: Russ Savage
function main() {
  //Let's reduce keywords with a CPC greater than $15 by 35%
  //And keywords with CPC between $10 and $15 by 20%
  var kw_iter = AdWordsApp.keywords()
    .withCondition("Status = ENABLED")
  while(kw_iter.hasNext()) {
    var kw =;
    var kw_stats = kw.getStatsFor("LAST_30_DAYS");
    var cost = kw_stats.getCost();
    var conversions = kw_stats.getConversions();
    if(conversions > 0) {
      var cost_per_conversion = (cost/(conversions*1.0));
      //Here is the magic.  If it is way too high, reduce it by the way too high amount
      if(cost_per_conversion >= WAY_TOO_HIGH_COST_PER_CONV) {
        kw.setMaxCpc(kw.getMaxCpc() * (1-WAY_TOO_HIGH_BID_REDUCTION_AMOUNT)); 
      //otherwise, if it is still too high, reduce it with just the too high amount
      else if(cost_per_conversion >= TOO_HIGH_COST_PER_CONV) {
        kw.setMaxCpc(kw.getMaxCpc() * (1-TOO_HIGH_BID_REDUCTION_AMOUNT));
      //no conversions on this keyword
      //we will deal with that later
And that's it. Stay tuned for the next installment where we tackle the keywords that are performing well by increasing their bids.
