Some points are about UX, others are about marketing and conversion...  &quot;Good&quot; is from the POV of the business, what is best for the business isn&#x27;t always what&#x27;s best for the user.  I, for one hate the large call to action&#x2F;subscribes that pop up at the bottom 1&#x2F;3-1&#x2F;5 of the screen, such as on this site.
