What’s the easiest way to evaluate if one version of your landing page performs better than another for the same ad?
Correct Answer
Run a Campaign Experiment on the existing campaign that switches between both landing pages
Why is this the correct answer?
Run a Campaign Experiment on the existing campaign that switches between both landing pages is the easiest way to evaluate if one version of your landing page performs better than another for the same ad because it provides a controlled, scientific A/B testing environment. This feature allows advertisers to split traffic between the original setup and a trial variation simultaneously, ensuring that external factors like seasonality, day-of-week trends, or sudden market shifts do not skew the performance data. By using a Campaign Experiment, you can isolate the landing page as the single variable while maintaining identical ad copy and targeting parameters. Google Ads manages the random distribution of users and provides statistical significance indicators, making it easy to see which version truly drives more conversions. This methodology eliminates the guesswork and manual labor associated with duplicating campaigns or comparing historical data, offering a streamlined path to optimizing your digital marketing ROI.
Why are the other options incorrect?
Replace the existing landing page with the new one and compare this month’s data to last month’s
Replacing the page and comparing month-over-month data is unreliable because it fails to account for seasonal variations or external market changes. This sequential testing method cannot isolate the landing page as the only factor affecting performance changes.
Create another ad group for the new landing page and compare the two ad groups
Creating separate ad groups for the new landing page often leads to internal competition and keyword overlap within the same account. This setup can distort the auction results and prevents a clean 50/50 traffic split needed for an accurate comparison.
Create another campaign for the new landing page and compare the two campaigns
Duplicating the entire campaign is inefficient and complicates budget management and reporting. It often leads to 'campaign fragmentation,' where data is spread too thin across multiple entities, making it harder to reach statistical significance quickly.
Real-World Example
A boutique fitness studio wanted to determine if a 'Free Trial' landing page converted better than their standard 'Membership Pricing' page for their local search ads. Instead of manually swapping URLs or risking seasonal bias, they chose to Run a Campaign Experiment on the existing campaign that switches between both landing pages over a 30-day period. By splitting traffic 50/50, the studio discovered that the 'Free Trial' variation increased lead generation by 22% with a significantly lower cost-per-acquisition. This data allowed them to confidently update their primary URL, maximizing their ad spend efficiency.
