It is a very big and complicated page. I don’t say that as a negative or a positive, merely a statement of fact. Are you measuring a conversion as a click through to the form or a sign up on the 3rd party site?
What keywords are you using? I only ask to try and see if message match is an issue.
I would consider making the statement about the insurance higher up on the page.
I would consider making your header/menu “sticky” or incorporate a back to top button.
Maybe you address this in the ads, but you don’t talk about who uses chiropractic services. Are your services just for people with back issues? Maybe adding a little client education component to the page will help people identify with your service offerings.
Also, maybe instead of a conversion being a $95 sale it is a form submit. You could say something like:
“Not sure if chiropractic care is right for you? Fill out this form and Dr. El-Hayek will get back to you and let you know if your condition/ailment meets his care guidelines and tell you about previous patient success stories.”
That way you are providing some security to people that what hurts them is something you can help with.
Maybe you want to offer a PDF about chiropractic care in exchange for an email?
It is a good looking page with great information. Make some tweaks with ad copy, landing page copy, do some A/B testing… you’ll start to reel them in!
