Create a strategic testing plan to ensure no test overlap and take remedial measures if the overlap is unavoidable.
Make a note of all coinciding tests in the spreadsheet and check if they can be prioritized.
If you need to test multiple web page components, run a multivariate test so that you can see the contribution of each variable on the result, and also their combined effect.
Use split testing if you want to test different page flows or complex changes such as a complete page redesign or to combine multiple hypotheses in one test.
Segment and analyze your target audience using a tool like VWO Insights and list the details in the spreadsheet for each test.
Segmentation can be based on demographics, visitor behavior, visitor psychology, or other data.
Before running a test, check whether your preferred A/B testing tool offers a traffic randomization option.
Go to Settings and look for traffic segmentation or mutually exclusive groups.
VWO offers traffic segmentation and randomization features that enable you to run multiple tests in parallel.
If you can’t keep the test audience separate using audience segmentation, enable the traffic segmentation and randomization feature in your testing tool. It will help randomize the visitors participating in your tests so that if a person becomes a part of one test, they’ll not become a part of the other tests.
If you’re using VWO as your A/B testing tool, use its inbuilt Mutually Exclusive Groups feature to randomize test traffic and avoid issues.
Make necessary changes if any errors are found in the quality check process.
