Google Ads Scripts to Improve Your PPC Performance

Google Ads scripts are here to stay. Specific scripts for PPC tasks should be at the top of your to-do list.

Search Engine Journal, Frederick Vallaeys

If you’re an Ads manager, you most certainly know that monitoring tasks and daily optimization of your campaigns can become a long and tedious task. To get rid of this tension, there are already certain measures to automate processes like implementing an automatic rule. However, there are times when automatic rules aren’t sufficient and you need an advanced solution, Google Ads Scripts.

Google Ads scripts help you automate repetitive, mundane tasks while providing you time to think deeply into bigger things like overall marketing strategy and budget.

In this post, I’m going to provide you with the best Google Ads Scripts that can help you improve your PPC efforts.

Account Management Scripts

View and change all your budgets on Google Sheet

With this script by Daniel Gilbert, you can modify and download all your budgets across multiple Google Ads accounts in a single Google Sheet.

The script first presents a complete list of all budgets for every account. You’ll have chance to analyze both shared and campaign-specific budgets. The best part is that you can also make changes from Google Sheet without doing the same on your Ads account.

Low quality score alert

With this script by Daniel Gilbert, you’ll be able to get rid of low quality score keywords.

The script below finds the low quality score keywords in your account and sends you an email alert. Depending on your choice, you can also pause or label these keywords found by the script.

Real time position bidding

With this script by BrainLabs, you’ll be able to automatically change the bids of labelled keywords with the help of automation.

The script runs every hour, thus letting you appear in target positions. The changes are limited to 20% so that you feel safe with your budget and account.

Automate your in-market audience

“The script looks at your campaigns’ CPC over a given time range and sets bid modifiers to each of the campaign-level in-market audiences based on performance.”

Reporting Scripts

Automated keyword performance reports

With this script by Philip Jones, you’ll have Keyword Performance Report for each specified account in a Google Ads manager account.

For each account, the script will create a seperate tab on Google Sheets. You’ll get an email with the export link when the process is completed.

• Copy this code to MCC level script tab.
• In code line 5, add account lds to the config.
• In code line 6, type in your email address to get export link automatically.

//** Script Developed by PMJ Digital **//
// Allowed Date Ranges TODAY, YESTERDAY, LAST_7_DAYS, LAST_30_DAYS
// For Custom date ranges use date format : yyyymmdd, yyyymmdd

    'accountIDs': [''],

Keyword performance script

With this script by Team Impression, you’ll have an overview as to exactly which keywords are contributing to the most of your success and which ones are consuming your Ads budget.

The script will present you logs as highlights; distribution of cost, conversions, and revenue. You’ll be able to see a variety of metrics for each keywords including CTR, Avg. CPC, conversion rate, clicks, impressions, and cost per conversion. Plus, you’ll get a cumulative percentage stat for which keyword is responsible for how much of the overall success/failure.

* [KPR] Keyword Performance Report
* Author: Nathan Ifill (@nathanifill), Impression
*
* This script gives you the distribution of cost, conversions and revenue
* (if you are pulling conversion value into your account) amongst your keywords.

* v1.1

Negative keyword conflicts by PEMAVOR

With this script developed by our team, you’ll be able to determine conflicting keywords in your ads.

The script below finds and records all conflict keywords for you to take appropriate action.

    //User reports
    // keyword_view : https://developers.google.com/google-ads/api/fields/v8/keyword_view
    // shared_criterion : https://developers.google.com/google-ads/api/fields/v7/shared_criterion

    //Declare label to mark keywords. 
    var labelText = "Blocked by Negative Test"
    var labelsArr = {}
        //foundIdsOnly will keep keywordId,adGroupId -> "keywordid:adgroupid" : [11111,22222]
        //Will use this object to call withIds method on AdsApp.keywords() method because Google Suggests : Use IDs for filtering when possible
    var foundIdsOnly = {}
        //Will keep negative word details for keywordIds incase we want to log it.  "keywordId:adGroupId" = { negativeWord: "keyword" }
    var foundArr = {}
        //Add filters if necessary. NAME IN ['NAME1','NAME2','NAME3']
        // var accountFilter = "Name IN ['NAME1']"

* MiniChecker
*
* A Google Ads script that carries out a selection of checks to assess account
* health, and emails the user its conclusions.  The checks that it carries out
* are:
* - Worldwide Targeting Checker.  Checks for any campaigns with worldwide
*   targeting
* - Keyword Bid Upper Limit Checker.  Compares bids to a user-set upper
*   limit, reporting any keywords that exceed this limit
* - Bid Modifier Upper Limit Checker.  Compares device, location and ad
*   scheduling bid modifiers to a user-set upper limit, reporting any modifiers
*   that exceed this limit
*
* Version: 1.1
* Google AdWords Script maintained on brainlabsdigital.com

Pause suspicious ads (invalid clicks)

With this script by Hoofay, you’ll be able to automatically pause the campaigns that get suspicious clicks.

Fraudulent bots organized by your competitors may lead to wasted spend. So, making sure of it with a simple code is a wise thing to do.

Identify duplicated ads

With this script developed by BrainLabs, automatically identify duplicate or entirely identical ads on your account so that you completely clear your account from duplicate clutter.

The script creates a report detailing which searches are triggering multiple ad groups. Copy the script below, then adjust the options at the top, such as: campaignNameDoesNotContain, ignorePausedCampaigns, checkUrl, metric, caseSensitive, keepLabel, and pauseLabel.
