Best website builder for makers, sellers and doers.

If you have members of your target marketing following you on social media, publish a post where you ask them to reveal any specific questions or challenges they have about your course topic. Just like with an email, you could share a link to a survey as an alternative to responding to you publicly (this might be the better option depending on the nature of your course topic).
The Sales Funnel explained

This was one of the most profitable funnels Clickfunnels has ever seen, and formed the basis of a supplement ecommerce business that generated >$500,000 a month in revenue. Clean and highly optimized, it combines multiple marketing strategies in a single relatively simple-looking page – a micro-commitment, a free offer, a video, money-back guarantee, call-to-action, and sense-of-urgency techniques. This mega-converting page leads to an optimized Sales page and not one but two Upsell pages, and then a Thank You page.
HelpScout starts their funnel with traffic. They have their blog and resource page that helps keep you clicking around their website. They make it very easy to see and easy to interact with and keep going on your journey around the site. The next step is the homepage. Their homepage is straightforward to understand. The design is quite clean and buttons to keep you moving around the site are quite prominent. When it comes to the last step of pricing and purchase, they never show a price menu; they just take you directly to a signup page. If you love the product and you’ve come this far, that is an aggressive but effective pricing strategy.
