You have a couple of options, you can use the platform's booking settings which allows people to book onto your event for free. There are no paid-for ticket options on the platform. If you want to manage your bookings elsewhere, or charge for tickets, you can link to an external booking website (like Eventbrite).
In the title, try to describe your activity in one sentence. Think of the words someone might type in to find your activity.
Search engines like Google cannot search an image. If you upload a poster, and nothing else, you will not have a successful activity. Users with accessibility requirements cannot adapt how a poster displays, but they can change the size, colour or format of the text you put in the description box.
For images, try to pick something inviting – remember this is an advert for your services or event. A logo isn’t as inviting as a photo of what the event is about.
Adding an expiry date is important to make sure that your event from 2019 isn’t still around in 2030!
Add relevant tags for the activity to make sure it's found by searching.
On some platforms (if enabled by the admins), you can restrict your new activity by account types. For example, you can add an event that is only for 'organisations'.
