Program (including a corresponding distribution for social reporters per session)
Visuals, for example a subdivision in the field of title visuals, speaker templates, quotes and animated infobits (for example to promote a study or certain services in a short video or GIF)
Handles and channels , for example a division of attendees, speakers, media (partners) and influencers)
Useful links (blogs on specific topics covered at the event, video content and other references)
Video descriptions and tags. Ideal to have ready in advance, so that you can publish at an event without having to think about these things
The above can of course be arranged according to your own insight. My experience is that such a division can help all parties (external and internal) a lot in the preparation and simplifies the approval process in advance.
Start content push
We assume a good registration process and a successful expected attendance buy bulk sms service percentage of visitors. We often start the content for the build-up to an event a week before the event. Are the registrations disappointing? Then start earlier, with the main goal of traffic to the registration page and the program.
For the content in the week before the event, you can think of highlighting speakers, flashbacks (highlights or speaker videos) to previous events, calling for participation in the conversation on a hashtag, announcing a livestream (freely accessible or behind a registration page) and links to an Android or iOS store for downloading an event app.
