This Enhanced Script automatically calculates the Lin Rodnitzky (L/R) ratio for your Google Ads account. This ratio is a quick calculation to see the efficiency of a Google Ads account, and 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. The script lets you set basic and advanced settings. 

You can either create a new setting selecting 'Create new setting' or 'Copy setting from an existing account'. To create a new setting, follow the steps below:

Range
