How to end an seminar I mean how to announce it to the crowd?

To effectively end a seminar, you can summarize the key points discussed and express gratitude to the speakers and attendees for their participation. Acknowledge any questions that may still be lingering and encourage further discussion outside the formal setting. Finally, announce any upcoming events or follow-up actions, and invite everyone to network and connect before leaving. Thank everyone once more and wish them a great day ahead.
