"According to the way of the world, when joy arises within a person or when sorrow arises, and she does not comprehend, she cannot bear it. Her heart momentarily flies away. But once she comprehends, she endures steadfastly and can bear it." - Zohar II:84b
you want to write your landing pages in such a way that (without feeling pushy) you make a strong case for your services, and you give them an easy way to sign up for therapy with you.
I typically suggest a four-part structure to accomplish this.
Provide information on the topic of the page. For instance, “What is depression?” or “How does trauma effect someone?”
Provide information on how therapy (in general) can help with that problem. For instance, “Solutions for depression” or “How can therapy help with trauma?”
Provide information on how you specifically are a great choice for helping with that problem – really make the case for yourself. For instance, talk about your many years of experience treating depression, or your passion for trauma due to your own past as a survivor.
Invite the reader to take the next step towards signing up with you, and make it really easy by providing a contact form, a big “contact me now” button, or something similar.
A few other thoughts:
I suggest that each section be at least a paragraph or two – it’s difficult for the client to really gain useful information if you share just a sentence here and a sentence there. However, don’t focus on word count or anything. Focus on your ideal client, the person who would benefit most from your services, and write the landing page that that person most needs to hear. That’s the most important thing.
