executeInParallel on More than 50 Accounts Using Labels

One of the biggest limitations for people running MCC level scripts is the 50 account limit imposed by the executeInParallel function. Until recently, one of the ways to get around this limit was to store the processed accounts list on Google Drive and update the file when needed.

Recently, the AdWords Scripts team enabled the ability to apply labels to each account from the MccApp object. With this, we gain the ability to write a much cleaner version of the script that uses labels to indicate when each account has been processed. Using this method and running this script every hour, you could process up to 1,200 accounts per day.

The following code is meant to provide a framework for you to substitute your own MccApp code into. You can then schedule this code to run every hour, and it will continue processing the accounts in your MCC until each one of them is finished.

It will also attempt to notify you when there are accounts that return an error so that you can investigate. The one caveat about this script is that if you run into timeout limits on the Mcc level, namely in the results function, you might not apply the label to each successfully completed account. You can solve this by replacing line 76 with the following and removing line 89:

applyLabelsToCompletedAccounts([result.getCustomerId()]);

Anyway, I hope this helps and let me know if you run into any issues in the comments.

Thanks,
Russ

Automated Creative Testing With Statistical Significance

In the spirit of the Holidays, I've got a little gift for everyone. This script will monitor your AdGroups for creative tests that have hit statistical significance and notify you with an email so that you can take action. The script keeps track of changes to any AdGroups so that it always knows when a new test has started without you having to keep track. It applies labels to your Ads and then notifies you via email when the tests have completed.

This script is based on my previous Ad Testing Script but has some additional features. Namely, instead of pausing stats based purely on a metric, this script calculates the statistical significance of the test before making a decision. The calculations are based on a blog post and spreadsheet from VisualWebsiteOptimizer that I modified to work with AdWords Ads.

I also incorporated the ability to link directly to the Campaign or AdGroup from the notification email which I posted about before. All you need to do is fill in the __c and __u parameters to enable that feature.

And finally, since this is probably the largest and most complicated script I've shared here, I used the logic from my post about Google Analytics reporting to fire a beacon whenever the script is ran. You are more than welcome to disable it (remove beacon(); from the second to the last line of the main function), but I would love to get an idea of just how many people are using this script.

Since this script is pretty big, and the formatting here can be a little iffy sometimes, you can also download it from GitHub.

Thanks as always for reading and have a fun and safe holiday.

Thanks,
Russ

Figuring Out When Your Ad, AdGroup, Keyword, or Campaign Was Created

Knowing when an Ad (or entity) was created is impossible using scripts. That information is simply not tracked in AdWords. The next best thing is to find out when your Ad first started receiving impressions and assume that is when it was created (If an Ad is created but no one sees it, does it really exist?).

So in order to help me keep track of when my Ads entities were created, I put together the following script to apply labels to my Ads entities with the date of the first impression. That way, I can find out what ads entities I created and make sure I don't take action on anything that is too young. I can also make changes to all the ads entities built on a given day relatively easily in the AdWords UI by just selecting the right label.

Thanks,
Russ

Finding Anomalies In Your Keywords, Adgroups, and Ads

UPDATE 2013-07-23: Added the ability to add labels to your ads as well. This might be helpful for creative testing.

In a recent post from SearchEngineLand, Larry Kim wants PPC Managers to stop being lazy. Link baiting aside, he has some good points. I think much of the time spent pouring over client spreadsheets is really trying to answer the simple question of "Where Are The Anomalies?"

Anomalies are keywords or AdGroups that seem to be performing very differently than their brothers and sisters in the same AdGroup or Campaign. Maybe you have an AdGroup with 15 keywords and one or two keywords seem to be getting nearly all of the clicks. Or maybe you just have an AdGroup that seems to be eating up a good chunk of your budget and you want to have more control over it. In either of these cases, you need some way to quickly identify which Keywords or AdGroups you want to take action on.

So I created the following script to help me do just that. It has a little bit of statistics embedded in it to calculate the mean and standard deviation of a set of entities (AdGroups or Keywords). Then I apply a label to any entity that seems to be more than two standard deviations away from the mean, which would indicate it is performing much better or much worse than its siblings. That way, I can take action on those entities pretty easily in my account.

This script will also send you an email each day with a summary of the entities that it deems to be anomalies. Your goal is to fix these issues by moving them into their own Campaigns and AdGroups or maybe even getting rid of them altogether (possibly negatives).

Right now, the script will check every metric that is available in the AdWordsApp.stats object. It could be easily modified to check for things like cost per conversion or profit per impression. You will see in the code below where you can remove stats that don't interest you as well.

One note of warning is that I do not claim to be a statistics guy, so this may or may not be a valid way to look at things. Hopefully, it will help you locate the issues in an account quickly and fix them so that you can spend more time being lazy :)

Also, I am open to your comments and suggestions for this script. Is it useful to anyone else?

Thanks,
Russ

Pause or Enable Campaigns, Keywords or Ads on a Specific Date

UPDATE 2013-12-13: Added the ability to work on Ads as well.

I've seen some questions posted around the forums asking about enabling or pausing keywords on a given day. It is pretty simple to do using labels and scripts. The following script will run through your account and look for keywords labeled with "Pause on " or "Enable on " and perform that action. If you would like to just use dates, you can set the two prefix values to be empty strings (""). The format of the date is YYYY-MM-DD (2013-05-01).

Thanks,
Russ

Merge Labels from Multiple Campaigns

This script is a follow up to one of my previous scripts: Merge Multiple Campaigns Together For Enhanced Campaigns Migration. This one is meant to run after you have merged your campaigns together and it will copy all the labels from the campaigns, adgroups, ads, and keywords from the ORIGIN_CAMAPIGN_NAMES into the DESTINATION_CAMPAIGN_NAME.

Russ

Automate Your Ads Based on Your Baseball Team's Schedule

I know everyone is focused on March Madness right now, but opening day for Baseball season is right around the corner. I wondered if it were possible to enable and disable specific ads based on the schedules of your local MLB team.

It turns out, the MLB has every team's full schedule in an easy to parse CSV format. All you need to do is search Google for " downloadable schedule" and look for the page that ends in "downloadable.jsp". It will look something like this:


The link you need is circled in the image above. You can see from the url what the team_id value should be in the code below. And if you right-click and download that .csv file, you will be able to see what value to use for the home_field as well. In the example below, I used my hometown teams of the Cubs and the White Sox, but you can use any teams you want.

The script itself will run through and look for a home game for your team. If the team is playing today and it is a home game, it will enable any ads that are tagged with the label you configured in the TEAM_INFO. If the team isn't playing a home game today, it will pause those same ads.

In the example below, I only used a portion of the data in the csv files. It would also be possible to enable ads only during the actual game, or enable ads for all game days, not just home games.

I encourage you to play around with the data and see what you can come up with. If you find anything useful, please leave a comment.

Thanks,
Russ

Label Countdown for Ignoring New Elements

Robert asked on one of my scripts how to ignore keywords that were recently added to his account. Unfortunately, the API doesn't give you a good way to do this although I figured there was a way to do it using labels.

So I put together the following script that you can use to automatically create a label-based countdown for elements that you want to ignore in your scripts. Each time you add new elements to your account, you can apply a label to it using the format LABEL_PREFIX_. So, if you want your scripts to ignore a new element for 30 days, apply the label "days_left_30" to that element. If you schedule the script to run every day, the number of days left on the label will be reduced by one each day. Once the number of days reaches zero, the label will be removed from the entity.

In the scripts that you want to ignore new elements, add the following function to the bottom of the script (before the last curly brace):

  function _build_label_list() {
    //Build a list of labels to exclude in your .withCondition()
    var LABEL_PREFIX = 'days_left_'; 
    var label_iter = AdWordsApp.labels().withCondition("Name STARTS_WITH '"+LABEL_PREFIX+"'").get();
    var label_array = [];
    while(label_iter.hasNext()) { label_array.push(label_iter.next().getName()); }
    return "'"+label_array.join("','")+"'"
  }

And then add the following
.withCondition("LabelNames CONTAINS_NONE ["+_build_label_list()+"]")
to any iterators you have in your other scripts. Good luck, and if you have any questions, feel free to ask.

Thanks,
Russ
