When you say “people landing there are not so likely trying out the class” are you referring to a low conversion rate? If so, what is your conversion rate (conversions/visitors*100)?
Also, do you know the main source of your traffic? This alone may be having a huge negative impact on your page’s ability to convert, whether you’re well ranked organically or not. The first most important step is to understand WHO is landing on this page in order to know why it’s not working and what you can change to improve it.
For example, you offer your courses in 5 different languages, but might be receiving traffic from English-speaking visitors only. Additionally, if you’re depending on organic traffic, you might be getting very unqualified traffic. Sadly, Google Analytics will never tell you where most of your traffic is coming from. Paid traffic, when done well, helps guarantee a level of intent in your services which leads to better conversion rates.
If you can give me some insight about the above points it would be a pleasure for me to give you more specific pointers.
Once the traffic issue is addressed, you can start focusing on building a landing page with content that is tailored to your intended audience, all while respecting certain “conversion rules”. For example, if you’re traffic finds you by searching “Meditation techniques” you may not want to mention “Sexual continence”. @Ashwin_Satyanarayana and @Nicholas also mentioned the important of 1 call-to-action, no external links, and concise skimmable content.
Lastly, I notice your offer for a free tryout lesson. Why not make that your main call-to-action. You might not even have to mention pricing at all since it can lead to confusion. Remind people throughout your page that they can attend their first session free of charge.
Hope this helped!
