H1 Headline -> Come up with a good headline. A big idea that hints that here is something your reader really, really wants (and can get from you).
Sub-headline -> For example, you may be selling a SaaS accounting tool, but the big message is: "Peace. Of. Mind." So explain here in clear and simple words what your product does and for whom it does it. And clarify the big claim you made in the headline.
CTA button -> Tell the reader what to do next
Add here logos of your biggest clients. Because social proof gives you credibility.
H2 headline ->Now that you grabbed your reader's attention you need to interest them enough to keep reading. The right way to do that is to write a headline that appeals to their self-interest. So explain here the consumer problem your product solves.
