What is Google Ads Automation?

Google Ads automation refers to tools and features that automatically manage your campaigns without manual intervention. This includes:

---

Smart Bidding: The Foundation

Smart Bidding is Google's machine learning bidding system. It automatically sets bids for each auction based on:

• User device and location
• Time of day and week
• Remarketing lists
• Browser and OS
• Search intent signals
• And 100+ other factors

Smart Bidding Strategies

Setting Up Target CPA

Go to campaign settings

Select "Bidding" → "Change bid strategy"

Choose "Target CPA"

Set your target CPA

Enable "Pay for conversions" (if available)

Setting Up Target ROAS

For e-commerce, Target ROAS optimizes for revenue:

Ensure conversion tracking includes values

Select "Target ROAS" in bidding

Set target as percentage (e.g., 400% = 4x ROAS)

Monitor for 2-3 weeks

Automated Rules: Set It and Forget It

Automated rules let you create if/then conditions that automatically adjust campaigns.

Common Automated Rules

1. Pause Low-Performing Keywords

IF: Keyword CPA > Target CPA × 2
AND: Clicks > 100
THEN: Pause keyword

Setup:

Tools → Bulk Actions → Rules

Create new keyword rule

Set conditions and actions

Choose frequency (daily, weekly)

2. Increase Budget for High Performers

IF: Campaign ROAS > 5x
AND: Impression Share Lost (Budget) > 20%
THEN: Increase budget by 20%

3. Pause Campaigns on Weekends

IF: Day = Saturday OR Sunday
THEN: Pause campaign

4. Enable Campaigns on Monday

IF: Day = Monday
AND: Time = 6:00 AM
THEN: Enable campaign

5. Alert on Spend Anomalies

IF: Daily spend > Budget × 1.5
THEN: Send email notification

Google Ads Scripts: Power User Automation

Scripts let you write JavaScript code that runs on a schedule in your Google Ads account.

Popular Scripts

1. Budget Pacing Script

Automatically adjusts daily budgets to hit monthly targets.

2. N-gram Analysis

Identifies search terms to add or exclude based on performance.

3. Quality Score Tracker

Logs historical Quality Score data (which Google doesn't store).

4. Anomaly Detection

Alerts you when metrics deviate from normal ranges.

5. Broken URL Checker

Pauses ads linking to 404 pages.

Basic Script Example: Pause High-CPA Keywords

function main() {
  var TARGET_CPA = 50; // Your target CPA
  var MIN_CLICKS = 100; // Minimum clicks to evaluate

  var keywords = AdsApp.keywords()
    .withCondition("Status = ENABLED")
    .withCondition("Clicks >= " + MIN_CLICKS)
    .withCondition("Cost / Conversions > " + TARGET_CPA)
    .get();

  while (keywords.hasNext()) {
    var keyword = keywords.next();
    keyword.pause();
    Logger.log("Paused: " + keyword.getText());
  }
}

Setting Up Scripts

Tools & Settings → Bulk Actions → Scripts

Click "+" to create new script

Common Automation Mistakes

❌ Mistake 1: Changing Targets Too Often

Smart Bidding needs time to learn. Changing targets weekly resets learning.

Fix: Wait at least 2 weeks between target changes.

❌ Mistake 2: Too Many Rules

Conflicting rules can create chaos.

Fix: Start with 3-5 essential rules, add gradually.

❌ Mistake 3: Ignoring Learning Period

Making changes during learning period confuses the algorithm.

Fix: Make significant changes (budget, targeting) outside learning periods.

❌ Mistake 4: Set and Forget

Automation isn't truly "set and forget." It requires monitoring.

Fix: Review automated actions weekly, adjust as needed.

❌ Mistake 5: Unrealistic Targets

Setting Target CPA 50% below historical CPA will fail.

Fix: Start with historical performance, improve gradually (10-20% at a time).
