Where to place the RSS button?

I am making a website and am confused as I don't know where to place the RSS button. Considering this is my website: My Website

Should I place the RSS button only on post pages? Or should I place it throughout the website? I'd like to clarify that I know where to place the RSS button in terms of layout(planning to place it on the top right corner), I'm asking where is it deemed useful and not annoying?
