How do you make a button more obvious?
Ensure the design puts emphasis on the primary or most prominent action. Use color and contrast to keep user focus on the action, and place the button in prominent locations where users are most likely to notice it.
How many buttons does a page have UX?
Don't have more than one primary action button on the screen at a time. Let users focus on the task at hand. You can have more actions on the page, but make sure there is only one primary. Users have expectations of what a single button on a page will do, based on the page they are on.
