Why is My Wordpress Site's Facebook Like Button a Different Count Than on the Connected Facebook Post?

Can you provide a link to the site/page?

I agree with . What you're seeing is the difference between an Open Graph object (your blog post) and your Facebook status update. They are two separate things. The status update has a life of it's own even though it contains the actual link which, admittedly, is a bit confusing. The actual blog post is tracked separately. You can access the information surrounding the data behind the blog post 'Like' number using the old REST API. I created a small bookmarklet for this that makes it easy to see this for the page you're on. http://www.blindfiveyearold.com/facebook-like-number-bookmarklets It still seems to work though the results for the page you reference in the comment are a bit odd. Nevertheless, the distinction you're seeing is that between an Open Graph object and an internal Facebook post. Hope that helps.

As a twist of what said, I'd like to add that:  "as opposed to the same post on our Facebook page" is not accurate. The Like on your WP site is tied to a URL. Perhaps its the whole site. Perhaps is page/post level. It depends on how to set it up. The Like on Facebook is a Like on Facebook. To you they pretain to the same content/subject. But to FB they are more of less Apples and Oranges. There might be a way to resolve that, but I'm not aware of it. I hope this extra bit of clarity helps.
