The Six Steps

There are six essential steps in each Optimizely Classic experiment. This section will show you each step in detail.

Step 1: Create a Variation

Making Basic Changes


Variations can be created in the Optimizely Classic Visual Editor. This video will show you how to make basic changes to your webpage and use Optimizely features like: select container, edit style, edit text, edit html, move and resize, rearrange, and more.

Additional resources:

The Code Editor


When you make a change using the Visual Editor, Optimizely creates a line of jQuery code that corresponds to the change you made. This video will show you how to use the Optimizely Code Editor to see, or make changes to, the jQuery that has been generated.

Additional resources:

Interactive Mode


Interactive mode allows you to interact with your page as you edit it, as if you were a visitor. This video will show you how to use Interactive Mode to show elements like drop-down menus or remove elements like pop-ups.

Additional resources:

Redirect Tests


The Optimizely Editor lets you modify a page to create variations. But you can also use Optimizely to test two completely different URLs against one another. This video will show you how to set up a redirect experiment, which will redirect your visitor to another page.

Step 2: Set Goals

Goals Overview


In Optimizely Classic, you’ll track conversion events by setting up goals. This video will give you an overview of how to set up and manage your experiments’ goals.

Additional resources:

Click Goals


This video will show you how to set up Click goals, which track how often your visitors click on a certain element.

Additional resources:

Pageview Goals


This video will show you how to set up Pageview goals, which track the number of unique impressions on a specific page, or subset of pages.

Additional resources:

Custom Event and Revenue Tracking Goals


Custom tracking events allow you to capture and report on visitor actions or events that might not be related exclusively to clicks or page views. The revenue tracking goal will track revenue from purchases or events on your site and attribute the amount to the visitor's experiment and variation. This video will show you how to set up custom event goals and the revenue tracking goal.

Step 3: Set URL Targeting

URL Targeting


URL Targeting allows you to specify the pages on which the experiment should run. This video will show you how to target specific URLs or groups of URLs depending on the match type selected.

Additional resources:

Step 4: Set Audiences



This video walks you through how to use Audiences, which allows you to control which visitors can see your experiment, based on whether they match a list of conditions that you specify.

Additional resources:



Dimensions are a way of classifying visitors into categories through Optimizely's JavaScript API. Optimizely stores data about every visitor to your page, like when they arrived, what device they used, and where they came from. This video will show you how to set up and use Dimensions.

Additional resources:

Step 5: Set Traffic Allocation

Traffic Allocation


This video will show you how to set Traffic Allocation, which you use to specify the percentage of visitors who will be included in an experiment and what percentage of those visitors will be shown a certain variation.

Additional resources:

Step 6: Preview and Test

Basic QA


Do a quick basic check that your variation is appearing, that it looks good, and that there’s no page flashing. You have two quick tools at your disposal: Preview Mode and something we call the Force Parameter. This video will show you how to use these tools to do basic QA for your experiment.

The Results Page

The Results Page Overview


Optimizely's Results page allows you to see your experiments' performance and explore your visitors' behavior. You can use the results on this page to make key business decisions based on the data you see. This video will give you an overview of the features and settings you can access from the Results page.

Additional resources:

Unique Visitors


Optimizely’s Stats Engine calculates winners and losers based on the number of unique visitors who enter your experiment. This video explains how Optimizely counts each unique visitor.

Additional resources:

Winners and Losers


This video shows you how to check if a variation won or lost, and how to compare your different variations.

Additional resources:

Conversion Rate


The conversion rate is a measure of the percentage of visitors who converted on the goal that you set. This video explains how Optimizely calculates the conversion rate and uses it to decide which variation won.

Additional resources:

Statistical significance


Statistical significance is a measure of how confident you can be in your results at that point in time. It can help you decide whether to keep the test running or to call a variation a winner and launch it to your site. This video explains how Stats Engine calculates statistical significance, and how you can change the significance level to suit your business' tolerance for risk.

Additional resources:

Difference interval


The difference interval shows you a range of values where your conversion rate is likely to lie, depending on the statistical significance threshold. It helps you interpret the trend of your data. This video walks you through an example of how to read the difference interval.

Additional resources:



Charts show you how well your experiment has been performing over time. You can use them to explore conversion rates for variations, compare different goals, share your results with stakeholders, and more. This video shows you how to find, view and share your charts.

Additional resources:



Segments allow you to filter your results, giving you valuable insights about different groups of visitors. This feature can help inform the next steps you should take in your testing program. This video shows you how to filter by segments on your results page.
