So I had searched a few sites, tried a few things, but nothing seemed to work. I have a customized Blogger template and I wanted to allow facebook comments on each post, not one post to the page (which is what the facebook dev page shows). There are a ton of other sites that reportedly show you how to accomplish setting up fb comments, but they didn't work for me. Why? I don't know. Below, I'll show how I did it. I'm not going to go through how to create a fb app, that part is covered on other sites and was never the issue for me. FB app id is not your FB user id. All pasting is done after the found tag.
1. Open blogger template html and find the html beginning tag. Inside it, paste this:
2. Next, find the head tag, AFTER it, paste this (replacing YOURAPPID with the fb app id)
3. Next, find the "body expr" tag and after it (replacing YOURAPPID with your fb app id), paste:
4. Find "data: post.body" and after it, paste
5. Save the template and you're done! it worked for my template anyway.
