Show video once on landing

There are so many great options you can use to provide this user experience. I would suggest trying different ideas but to get started you can choose a WordPress plugin to provide this, look at these for example https://www.ads-software.com/plugins/search.php?q=first+visit+popup and I would suggest vetting these by looking at reviews and number of reviews and compatibility rating of each plugin to make sure it jives with the most recent v. of WordPress. Cheers!

Thanks Matty! Great info.
