This Enhanced Script automatically calculates the Lin Rodnitzky (L/R) ratio for your AdWords account. This ratio is a quick calculation to see the efficiency of an AdWords account. It is calculated by dividing the cost per acquisition or conversion (CPA) of all search queries with the CPA of search queries that have more than one conversion.
The L/R ratio can be used as an indicator of the efficiency of an account. This score divides the CPA of all search queries by the CPA of all your search queries with at least 1+ conversion. A score of under 1.5 indicates that the account is too conservative or brand heavy and a score of greater than 2 suggests too aggressive of a strategy.
Choose the account you want to run the script in and go to the All Enhanced Scripts page. This Enhanced script is quite simple to set up as there aren't many settings.
