Embed.ly allows you to easily embed your blog posts, webpages, or other information into other sites/blogs by creating an embed code for you when you enter a URL. It also makes sharing your information easy as it includes a "re-embed" button (like retweeting) and an option to share on Twitter or Facebook.
Below, I share a Google doc I created with brief information about Boolean searching. You can see the "re-embed" and share buttons in the upper, right-hand corner of the card Embed.ly creates. You can also select to see the original source of the embedded information.
