Recently, we found that displaying the “core ask” for supporting The Daily Signal to “returning” visitors to the donation microsite increased results over a traditional membership ask. In phase 2 of this experiment, we decided to further experiment with a “membership ask” vs. a “core ask” to support The Daily Signal to “new” and “returning” visitors.
Will showing a “membership ask” to “new visitors” to The Daily Signal increase donor conversion rate over a “core ask” for The Daily Signal?
|Treatment Name||Conv. Rate||Relative Difference||Confidence|
|C:||TDS Core Ask (Control)||0.01%|
|T1:||THF Membership Ask (Treatment)||0.02%||305.4%||95.5%|
This experiment has a required sample size of 41,329 in order to be valid. Since the experiment had a total sample size of 81,249, and the level of confidence is above 95% the experiment results are valid.
Flux Metrics Affected
The Flux Metrics analyze the three primary metrics that affect revenue (traffic, conversion rate, and average gift). This experiment produced the following results:
0% increase in traffic
× 305.4% increase in conversion rate
× 0% increase in average gift
With 95.4% level of confidence, we found that the “membership ask” for “new visitors” increased donor conversion rate by +305.4%.
The other metrics impacted were:
- Dear Reader ad clickthrough rate: +83.7% (level of confidence: 100%)
- Revenue: +929.7% (level of confidence: 99.6%)
These findings further validate the hypothesis that serving a membership ad to new visitors to The Daily Signal will not only be most effective at driving “Dear Reader” ad clicks, but will also substantially increase donor conversion and revenue gained from visitors arriving at the donation microsite.
The other half of this experiment is still running, but will help determine whether or not promoting The Daily Signal “core ask” to “returning visitors” is the most effective at generating donors and revenue from the ads.
