How to Create a Powerful A/B Testing System Using Google Ads and Convert

Optimize conversion rates with Google Ads and Convert A/B testing. Learn how to split traffic, track performance, and improve marketing ROI.

Overview

In the competitive world of digital marketing, optimizing conversion rates is essential for maximizing ROI. By combining Google Ads for traffic distribution and Convert for landing page variations, you can create a robust testing system that delivers actionable insights. This guide will walk you through setting up this powerful testing framework. 🎯

Understanding the Integration Strategy

This strategy uses Google Ads to split traffic between different landing page variations created in Convert. Instead of creating separate pages for each test variation, Convert’s Force Variation Links will be used to direct users to specific variations of the same landing page. 🔗

Prerequisites

Before getting started, ensure you have:

  • An active Google Ads account

  • A Convert.com account with experiment capability

  • A landing page ready for optimization

  • A basic understanding of A/B testing principles

Step 1: Setting Up Your Convert Experiment

Create Your Experiment

  1. Log in to your Convert account and navigate to the Experiments section.

  2. Click Create a New Experiment and configure:

    • Landing Page URL

    • Select A/B Test as the experiment type

    • Give it a descriptive name (e.g., Homepage CTA Test - July 2023)

  3. Create your variations:

    • Variation A: Control (Original Page)

    • Variation B, C, etc.: Modify elements like headlines, images, CTAs

  4. Save each variation. 💾

Configure Targeting & Goals

  • Set up audience targeting if needed.

  • Define conversion goals (e.g., form submissions, purchases).

  • Save experiment settings.

Generate Force Variation Links

  1. Navigate to Experiment Summary > Variations > Preview > Force Variation section.

  2. Convert will generate unique URLs for each variation.

  3. The Force Variation URL format:

    https://www.convert.com/?_conv_eforce=100128037.1001188067
    • The first number represents the experiment ID.

    • The second number represents the variation ID.

  4. Copy these URLs for use in Google Ads.

Step 2: Configuring Your Google Ads Campaign

  1. Log in to your Google Ads account and select your campaign.

  2. Create a new ad group or use an existing one.

Set Up Multiple Ad Variations

  • Each ad should be identical in copy and creative.

  • The only difference should be the Final URL (destination URL).

Assign Force Variation Links

  • Ad Variation 1: Use the Force Variation Link for Variation A.

  • Ad Variation 2: Use the Force Variation Link for Variation B.

  • Repeat this process for additional variations.

Adjust Ad Rotation Settings

  • Navigate to Ad Group Settings > Ad Rotation.

  • Select "Do not optimize: Rotate ads indefinitely".

  • This ensures equal exposure to each variation.

Step 3: Setting Up Tracking and Analytics

Google Ads Conversion Tracking

  • Ensure Google Ads conversion tracking is enabled on your landing page.

Add UTM Parameters

To track variation performance in Google Analytics, append UTM parameters to each Force Variation Link:

?utm_source=google&utm_medium=cpc&utm_campaign=[CAMPAIGN_NAME]&utm_content=variationA

Connect Convert with Google Analytics

  • Link Google Analytics to Convert to track user behavior.

  • Set up conversion tracking in Convert to match Google Ads goals.

Step 4: Launching and Monitoring Your Test

Launch

  1. Activate your Convert experiment.

  2. Enable your Google Ads campaign.

Monitor Performance

Track key metrics on both platforms:

  • Google Ads: Click-through rates (CTR), Quality Scores, CPC.

  • Convert: Conversion rates, bounce rates, user engagement.

Allow enough time (typically 2-4 weeks) for statistical significance. ⏳

Step 5: Analyzing Results & Implementing Insights

Compare Key Metrics

  • Conversion rates

  • Engagement metrics

  • Return on ad spend (ROAS)

Identify Statistical Significance

Use Convert’s reporting dashboard to determine winning variations.

Take Action

  • Implement the winning variation as the new control.

  • Document learnings and plan the next test.

Advanced Optimization Tips

  • Use Google Ads audience targeting for segmented traffic analysis.

  • Implement dynamic keyword insertion to match ad messaging to landing pages.

  • Test multi-step conversion funnels for deeper insights.

  • Ensure ad-copy alignment with landing page variations to maintain consistency.

Troubleshooting Common Challenges

Inconsistent Traffic Distribution

  • Check Google Ads campaign to ensure even ad spending.

  • If necessary, adjust bids or use a campaign experiment for fixed traffic allocation.

Difficulty Tracking Cross-Platform Performance

  • Use consistent UTM parameters.

  • Set up Google Analytics as a central reporting hub.

Low Statistical Confidence

  • Extend test duration.

  • Increase ad budget to drive more traffic.
