• Enter Multivariate Testing

6
What it Does

• Formalizes, checks and tests on the individual
  components rather than considering full
  pagesFocuses on identifying the winning
  combination from a set of all possible
  combinations

7
Generating Accurate Results with Multivariate
Testing

• Each test consumes a certain amount of traffic
  before appropriate results are received More
  traffic is required in multivariate software
  testing in contrast to A/B testing

Good Candidates for Multivariate Testing

• Concurrent testing of visual elements text on a
  given webpage
• Text color testing of call-to-action button
  simultaneously

• Multivariate Software Testing Vs. A/B testing

Multivariate Software Testing A/B Testing
Different versions of multiple elements are setup, which are combined with the help of a testing tool to eventually determine best possible combination Two or more versions of a complete webpage are compared to determine the better combination
Effectively tests multiple variables simultaneously to arrive at the ideal solution Tests only one variable at a time
Effective when existing landing page or website is to be optimized with minimal focus on redesign effort Effective when organization has evaluated multiple ideas to recreate a page and wishes to test them against one another
Does not require full redesign, hence limited investment is required May require complete redesign, hence investment may be relatively more
If implemented properly, first test run can yield desirable results and point towards the optimal combination Mostly, the first run will not give the best possible version the developers or testers are looking for
Requires more traffic and real-time scenarios to generate appropriate test results and hence, the winning combination Requires relatively less traffic as compared to multivariate software testing

• Types of Multivariate Testing

11
Full Factorial Testing

• This is the most preferred type of multivariate
  testing
• It is done by giving equal justice to each
  component combination

• Picture here

12
Adaptive Multivariate Testing

• This is a recent approach wherein user feedback
  is given importance
• Analysis is charted to determine best possible
  combination based on the real-time responses of
  website visitors

• Picture here

13
Fractional Factorial Testing

• Only a certain number of component combinations
  are exposed to the site traffic
• Rest of the combinations undergo analysis to
  determine best conversion possibilities

15
Challenges

• Website traffic that needs to be generated for
  test resultsThe size of sample traffic needs to
  be projected in advance to ensure result
  evaluation happens

16
Benefits

• Large number of variations can be analyzed in
  limited time frame
• Enterprise level results have indicated better
  brand awareness
