You can market and advertise indefinetely, however, if your page isn’t set up like a high converting sales funnel, then you’ve missed the chance to score on your own basket.
Here’s how to do it:
Create a simple, yet effective, marketing funnel in place, including a bridge (i.e. blog post, article, etc.), landing page with email opt-in, thank you page that offers an immediate sale (to can see if they’re actually interested in buying or not), and an initial upsell to get them spending.
To finish off your sales funnel, get a segmented and targeted email campaign running, making sure to drive traffic. Lastly, check the results, and do some a/b testing to see what to implement next time you go over this process.
