You have understood why we were counting URLs (if not look at the related question).
The subscription proposal provides you with a maximum volume of URLs per month.
Depending on the number of projects and the way you work on a site, you will need a more or less frequent use of our crawler.
When we correct a theme, when we modify templates, we like to get a quick feedback on the corrections made.
If you write on a weekly basis, you will need a weekly crawl.
In the application area http://app.mitambo.com you can manage your profile (your subscriptions, …) but also the parameters of your crawl project.
