Nelio A/B Testing is compatible with cache systems (including WordPress-specific cache plugins). When loading alternative content, Nelio adds one or more GET parameters in the URL:
- Post One
- Headline A
- Headline B
- Post Two
- Headline X
- Headline Y
- A visitor sees both original versions: A X
- A visitor sees one original version and one alternative: A Y
- A visitor sees one alternative version and one original: B X
- A visitor sees both alternative versions: B Y
- Group 1
- Experiment A (4 alternatives)
- Experiment B (4 alternatives)
- Group 2
- Experiment C (4 alternatives)
- Experiment D (4 alternatives)
- Group 3
- Experiment E (4 alternatives)
You can configure Nelio A/B Testing to use (or not) the previously described solution. Just go to Nelio's Settings and modify the value of the option called Test Mode:
- Group Experiments and Divide Visitors: your experiments will be divided into groups (as we just described). This will reduce the total amount of possible combinations, but each of your visitors will only participate in some experiments (that is, she'll participate in the experiments of one group or the other, but not in all of them).
- Test All Experiments with All Visitors: experiments won't be divided into groups and all visitors will participate in all experiments.
Moreover, if you want to completely get rid of the exponential combination problem, also make sure to disable Site-wide Consistency.
