We don’t show the signup cta by default because sites that prompt you to sign up on your very first page-view are annoying. We only show it if the user has expressed some interest in your site.
The requirements are as follows:
the user must have a total reading time of at least 2 minutes
ANON_PROMPT_READ_TIME is defined here
the user must view more than two topics on your site
ANON_TOPIC_IDS is defined here
Once those requirements are met, the cta will be shown, otherwise, it won’t.
