Automagically adds Open Graph tags to your blog. Control how your posts and pages are presented on Facebook and other social media sites. No configuration needed.
When someone likes or shares your blog on Facebook, your header image is shown. If someone likes or shares a post, the featured image (post thumbnail) is shown. If you haven’t selected a featured image, then the plugin looks for the first image inside the post. If there aren’t any images in your post, then your blog’s header image is shown.

Content Cards make ordinary web links great by making it possible to embed a beautiful Content Card to link to any web site.
By using OpenGraph data, Content Cards grabs the title, description and associated image to the links you embed – it’s similar to how you can embed other websites, such as YouTube, Twitter, SoundCloud and more.
For individual links, You can insert a Content Card via shortcode <code>[contentcards url="http://yoursite.com/article-1"]</code>. If you often use Content Cards for some website, you can register the domain name (for example: <code>yoursite.com</code>) as an oEmbed provider via Plugin’s Settings page and then it will behave the same way other oEmbed providers do – you will just have to paste plaintext link to a separate paragraph an Content Card will be generated automatically.
