The strength of this is that you can give more information about yourself and your writings.
Those who are interested in you can find out more about your work and views here, as this is your official website. Also, here you can indicate what services you can provide in addition to your existing books. Such a service can also be payroll writing and proofreading. The number of pages is usually between 1 and 5, which also includes a contact form.
This type of website is primarily for those who do not make a living primarily from writing, but only do it as an income supplement or hobby.
