How to automatically add text to the end of new blog posts?

Is there anyway to automatically add some text to a blog post when it’s published? I have some standard text with links to twitter/facebook etc (about a paragraph worth) that I copy/paste onto the end of each blog post - it would save a bit of hassle if there was some way to just automatically attach this text when publishing a blog post.

I‘m not quite sure I understand you correctly, but I guess I would add such things to the template file. Although that probably only works if you had were using your own theme.

That sounds like the best option, thanks. I was trying to think of a twig or php solution but didn’t actually think of the simplest option of just editing the template file.
