I think something on your own site that points to the webinar pages on ON24 is best. That gives you a lot of flexibility to determine how the content is presented and organised, and you can even use an identifier in your marketing automation platform, likely the e-mail address, to pull user data and offer known visitors a link directly to the webinars without having to register again.
Those who haven't registered, or who've dumped their cookies would have to register, but that means you can continue to capture new leads the same way you did your initial registrations, and, if you have an integration, you can:
- Log the source on the lead's record the same way you would other webcast registrants using the partnerref variable. (You can even use script on your page to dynamically add that if they arrived at at your webcast listing page via another source.)
- Enter the leads into your marketing automation platform, and push them into marketing programs/lists/enagement programs the same way you did with other registrants.
- If your MAP is integrated with your CRM, you can push those leads into your CRM based on whatever rules/flows you like.
If you have different audiences, some tagging on webinar objects in your CMS can control who's presented with what and you have more freedom there to generate supporting content dynamically, if you know who the person is, that can improve their experience on your site.
This also means that their webcast experience with you is consistent, whether they make their way to a webcast through the site, an invite, a share, et cetera.
