So don't insult your potential client's intelligence.
The typical ones this is not for you but…
You can use this section but without treating your potential client as if they were unintelligent.
You can say things like , “This isn’t for you if you haven’t taken the advanced course before,” or “This isn’t for you if you don’t intend to pursue a career in digital marketing.”
But you can't say things like , "This isn't for you if you're not a luxembourg mobile database brave person who wants to make a lot of money with your online business," or, exaggerating, "This isn't for you if you don't dare to jump off a fifth floor with your eyes closed."
Do you see the difference?
There are times when I see pages that use these arguments, and if you look closely, you can see that they are playing with the need that we detect earlier and earlier... and they work less and less.
In addition, it will make you lose credibility and that is one of the main mistakes that, if you make, will prevent you from selling with your sales page.
Another thing you shouldn't do is try to get your potential client to do multiple things.
