I want to share a post to say Facebook but the SEO in the article post combines the SEO for the post as well as the SEO from the homepage. I tried changing the SEO from the homepage to make it less but it now still shows the old SEO description. How can I set it to share so that it only shows the SEO I put in the blog post and not all SEO from site and post? I would want it to just have title of blog post folowed by the name of our site only.
