I figured out how to make it so people can embed my content on their site(s) thanks to the DP community, but I wanna know how letting people embed my games help me out in any way?
Well, inmost cases there would be your logo, website address and other advertisements on the embedded material, so in essence by allowing people to embed your content, they are also advertising for you on their site Another benefit should be that if people click through, they will go to your website, giving you traffic that you would have otherwise never had access to. It's also a link back to your site, which is good for your SEO.
