What is Google Optimize?

Google Optimize is a tool by Google that lets you test different elements on your landing pages. You can set an objective and then see which variation of your page performs well.

The best thing about Google Optimize is that it uses the power of Google Analytics to measure your experiments. And you can see instant results to optimize your campaigns.

So, what can you do with Google Optimize? Here are some the benefits of conducting split tests with the tool:

  • Create Landing Pages that Convert: You can A/B test your landing page with different CTAs, headlines, and content. Then use the data to see which page converts the best.
  • Reduce Bounce Rate: If you’re having difficulty keeping visitors on your website then you can run a split test. By changing different elements in your content, you can find a winning combination that reduces the bounce rate.
  • Optimize Banner Design: Creating banner ads can be hard work, but how do you know which design will produce results? Through split testing, you can obtain data about banner design and elements you should be using.
  • Improve the ROI of Your Marketing Campaigns: Since promotional activities can cost money, you can use A/B tests to reduce the risk of failure. By understanding what’s working, you can improve the ROI of your campaigns and avoid mistakes.

Now, let’s go through Google Optimize tutorial and see how you can conduct split tests on your website.

And that’s it! You’ve now successfully added Google Optimize to your WordPress website. So, what’s next? Let’s set up your first experiment.

How to Create a Simple Split Test Using Google Optimize?

After setting up Google Optimize, you are ready to create a split test for your website.

Step 1: Set Up Your First Experiment

To start, go to your Google Optimize homepage and under the Experiences tab, click Let’s go to set up your first experiment.


You’ll have to give a name for your experiment, enter the URL of your webpage, and select an experiment type. For setting up a split test, choose the A/B test option.


Once you’ve entered the name of the experiment and selected the type, click Create.

Step 2: Create a Test Variant

Now, set up a variant for your experiment. For this, click Add variant under Targeting and variants tab.


Your variant should now appear in the Variants option. Click Edit to make the changes to your landing page for the experiment. Do note, you’ll need Google Optimize Chrome extension. It’s a visual editor that lets you edit your landing page and create a test variant.


Let’s say you want to test the heading of your landing page and see which headline works best. For this, select the heading and then click Edit element.

Then select any Edit text or Edit HTML and enter your heading for the test variant. Once you’ve made the changes, click Done (it’s located on the top right corner).


Step 3: Add Experiment Objectives

Now the last thing to do before running your split test is to add experiment objectives. You will have 2 options, either you can select an objective from a list or create a custom objective.


In Choose from list option, Google Optimize will offer pre-built goals in Google Analytics for your experiment. These include bounce rate, pageviews, and session duration.


But if you select Create Custom option, you’ll have to define a goal so that Google Analytics can track your objective.
