Your copy can only get your readers to take action if they actually read it.
And the way you present it on your website or landing page makes a big difference in that.
I regularly come across common design mistakes that give readers a hard time.
It should be a few font sizes bigger than the body copy. Period.
Long paragraphs of dense text look anything else but inviting and easy to read. The solution: more line breaks!
We read in an F-pattern. If our eyes don't have a left border as a reference point, we get lost. Left-align your body copy!
The eyes of your reader will get tired if they have to travel back and forth this far. Place your body copy in a narrow column instead.
It has to stand out so your reader can't miss it. Use a bigger font, color, or even arrows to draw attention to your CTA.
Keep in mind: The goal of your page design is to amplify your copy and present it in the best way. Not to just look pretty.
