How can I publish a deb package?

I don't know much about packaging and it took me a a week to create a working deb for my software. Now I need a way for people to install it and I don't want to just create a download link for the deb. How can I do this? I considered a ppa, but all the resources online seem too complex for me to understand. Also, can I publish it to the apt package manager. Please help since I said, I don't know much about this.
