Google+ Hangouts on Air are a great way to interact with your fans and have a sort of modern-day meet-and-greet over the internet. Informing people about it is easy, you just tell people when it is and then they’ll hopefully show up at the appointed time. But that can be kind of annoying, looking for a Hangout when a simple link could just take people there. Since Hangouts was introduced, the link would only appear when the Hangout was ready to go. Well now, YouTube and Google+ have teamed up so that you can create a link you can send out to all of your followers and it will last forever and ever.
A Permanent Link for Your Google+ Hangout-On-Air
So this is how to get a URL for your Google Hangouts-on-Air well before it’s ready to broadcast, so you can send it out in an e-mail list, or Tweet it, and so your followers can also share it.
Take this link:
Replace USERNAME with the name of your channel.
If you don’t have a live hangout at the time the link is clicked, it will redirect to your homepage. If you do have one going, it will direct users straight to the hangout. This permanent link can always be used for any hangout in the future.
