I love using Google Slides as an alternative to PowerPoint because of it's accessibility and ease of integration to all the other great Google apps we use in my district, but one feature that many colleagues have asked for is getting a presentation to play on repeat and have the slides hold for longer then 3 seconds.
Currently the only way to accomplish this is to publish your presentation to the web which will allow you to change the slide length and have the presentation repeat itself automatically. You can then either share the link or use the embed code (see presentation below) to insert a presentation into a website or other platform for people to view.
One worry my colleagues have regarding publishing is the fear of everyone and anyone accessing this information. One way to avoid this is the check box that requires someone sharing your domain in order to see the content (see image). Now what decide you publish should definitely be a consideration, but with the abundance of content out there in the world wide web, you are but a tiny piece of sand on the beach that is the internet (metaphor alert!). I wouldn't worry too much about anyone but your target audience seeing your content, but you should only publish content you are comfortable with being accessed by anyone. By publishing your information you never know who you might help, so don't be afraid to share your thoughts with the world!
