Consent rate calculation
Didomi considers consent as an end-user who accepts at least one purpose or vendor associated with the consent notice on your website/app.
The consent rate is the percentage of end-users who have given consent (opt-in) over all the users that have replied with a choice (opt-in or opt-out) to the consent notice. That is, when an end-user made a choice in a consent notice, what percentage of those choices were opt-ins.
The formula Didomi utilizes to calculate consent rate is: Consent rate =(opt-ins / total choices) * 100
Note: Consent rate is different than opt-in rate. Click here to learn more.
Consent notice format
The centered pop-up format consent notice was the most popular format used by Didomi clients and also had the highest consent rate. This format interrupts the end-users interaction with the website/app until an action is taken.
While other consent notice formats (footer, header) have similar consent rates, the volume of end-users who did not interact with the consent notice (no choice rate) increased considerably since they were allowed to browse the website without making a consent choice.
Consent rate performance based on options to refuse consent
In the table below please find how refusal options presented in consent notices impacted consent rates:
| Refusal option | Consent rate |
| No refusal option |
90.4% |
| Link only |
79.8% |
| Button only | 74.7% |
| Cross only | 62.5% |
| Button and cross | 56.5% |
While the above represent the reality of the market, it does not necessarily correlate to good privacy and compliance practices. Please make sure to always consider compliance with applicable laws when configuring your consent notice
Recommendations
In this list below please find some common recommendations your organization can implement to improve your consent notices:
-
A title on your consent notice, such as "Privacy is our priority".
-
Match the style, font and content of your banner to your website.
-
Grouping purposes into (user-friendly) categories facilitates granular choices.
-
Didomi cross-device feature can be useful for sharing consent across different websites and apps, whether on the same or different devices. This improves both your organization's monetization and consent rate, because your organization does not have to ask the same end-user for consent multiple times.
