If you own your own business or want to talk about how to publish a book or any other topic on which you are an expert, you may want to consider a webinar. If you do, keep in mind another key to a successful webinar is getting the word out about the seminar.

Part of the content is knowing who your target audience is and why the webinar would appeal to them. This information also will help you decide what platforms to use to promote the webinar.

Here are four platforms for promoting the webinar:

Blog: If you have a blog, promote the webinar and include the details about the webinar and relevant details about the speaker’s background. Also, describe the benefits of attending and include the link to sign-up. Hubspot wrote a great blog about writing content that has impact with examples. It then included details about a webinar.

Website: Promote on your website. If you don’t have one, you may want to create one so you can share relevant content with your audience.

Email: If you own a business or have a mailing list, notify everyone by email. I also would encourage you to send a follow-up email because people need to hear the message more than once. As you do more webinars be sure to include testimonials so that people will understand the benefit.

Social networks: Promote your event on the social networking sites, including Facebook, LinkedIn and Twitter. You can post a few times but do it at different times or days to reach different audiences. And invite them to share with their networks.
