Question: What is A/B testing?
- A statistical model that helps you define the credit assigned to each interaction a visitor takes along their buyer's journey at your organization.
- A type of marketing experiment where you split your audience to test a number of variations of a campaign to determine which performs better.
- A measure of the likelihood that the difference in conversion rates between a given variation and the baseline is not due to random chance.
- A type of marketing dashboard that helps you measure how well you're solving for your buyer's as they progress through their buyer's journey.
or
- Testing that compares the performance of two campaigns that differ by one variable.
- A measure of which brand or brands are the first to come to mind when respondents see or hear a particular campaign slogan.
- A measure of the percentage of respondents that recall which brand uses a particular message in its advertisements.
- Survey-based research that measures the impact of ads on consumer attitudes and perceptions related to your brand.
Explanation
A/B testing is a controlled marketing experiment that compares different versions of an asset to see which performs better. In HubSpot, effective A/B testing isolates one variable so performance differences can be tied to the tested change. Results should be evaluated with performance data and statistical significance, not preference. This supports inbound optimization by improving content, emails, pages, or campaigns based on evidence.
Why the other options are incorrect
Attribution model assigns credit to interactions across a journey, not campaign variation testing.
Statistical significance measures confidence in a test result, but it is not the test itself.
Marketing dashboard reports performance data, but it does not define a controlled experiment.
Brand recall measures whether people remember a brand from a slogan or message.
Message association measures whether people connect a message with the correct brand.
Ad impact research measures perception changes from advertising, not version performance testing.
