Monitor Broken Links Using MCC Level Scripts

Note: I recommend you take a look at the official solution from the AdWords Scripts team before implementing this solution.

For anyone who didn't know, they are finally here in Beta form. AdWords scripts are now available at the MCC level. If you want access to these beta features, all you need to do is apply here and wait for the team at Google to give you access.

So what's new with MCC level scripting? The full details are at the Google Developers page, but here is a summary. You can now kick off selectors on Accounts by using the MccApp object. Filtering by stats is the same as other selectors only now you run it at the account level.  As you work through each Account, once you set the account you want to work on using MccApp.select(), everything works just like it used to.

The one new function you will probably want to take advantage of is executeInParallel() which allows you to execute the same code across up to 50 accounts at the same time. So you can kick off a reporting script to run across all of your accounts, then collect the results and send a single email or store it to a single spreadsheet. Also, scripts can now run up to 60 minutes using this method since you get 30 minutes of execution time to run the code on each account and 30 minutes to collect the results from the callback function.

To get you started with the new MccApp object, I thought I would take one of my most popular posts and rewrite it to run at the MCC level. Finding Broken Urls in your Account is a great example of how you can leverage the new executeInParallel() function to improve the monitoring of your MCC.

This script works very similarly to the previous script but has a few added features.  This script will check all your Keyword and Ad urls once per day. When you install this script, you should schedule it to run hourly in case there is a large account which can't be processed in the allotted timeframe, it can pick up from where it left off and continue processing. It controls this internally using labels.

Also, the results of this script are stored in a new spreadsheet for each run. I had issues with the last one where the script would overwrite the values in the spreadsheet before I had a chance to look at them. This eliminates that issue.  The spreadsheet is accessed from a summary email that looks like this, with each row containing a link to the spreadsheet tab with that account's results.
An Example Email from the Script
There are a few other features such as the ability to notify you when errors occur, report on redirects, and setting any number of response codes you are looking for.  Take it for a test drive and let me know what you think in the comments.

Also, just a quick note that I am getting back in the swing of things after getting married at the end of March so look for a much more frequent posting schedule. I am speaking at the Marketing Festival in Brno, Czech Republic at the end of October so I look forward to meeting anyone who can make it.

Thanks,
Russ
