The third step to validate your speaking niche is to create a landing page and an email list. A landing page is a web page that showcases your speaking offer and invites visitors to take a specific action, such as signing up for your email list, downloading a lead magnet, or booking a discovery call. An email list is a collection of email addresses that you can use to communicate with your audience, build trust and rapport, and pitch your service. This combination of landing page and email list can help you measure the demand and interest for your offer based on the traffic, conversion, and engagement metrics. You can also test different elements of your offer, such as the headline, subhead, bullet points, testimonials, and call to action. Additionally, segmenting your audience based on their preferences, needs, and behaviors will help you nurture your leads with valuable content, stories, and offers. Ultimately, this can lead to bookings and referrals from your subscribers and fans.
