Give netlify a try https://www.netlify.com

It's like GitHub pages on steroids (SSL, redirects/rewrite rules, proxying, domain aliases, etc, etc...). It'll run any build tool for you (not just Jekyll) and we have built-in support for Hugo:

I like Wercker which works well on github pages, s3 and ssh. There's a good tutorial at https://gohugo.io/tutorials/automated-deployments/

I just used this technique for https://stevefrancia.com and the wercker files are at https://github.com/spf13/stevefrancia.com

I just build locally and push the results to GitHub. Master branch is the generated site, hugo branch is for the code.

I use a git hook that builds locally on commits to master (with some cleaning just in case I was testing weird things from non-master). I host on s3, but I don't think the s3 transfer vs github push is of great consequence here.

Wercker's a great option with Aerobatic & Bitbucket. Here's a blog post on how to set it all up: http://www.aerobatic.com/blog/hugo-continuous-integration-wi...
