automatic social share images
When I built my post template I added the most basic "meta" tags like author, description, and keywords. Sites like Twitter are smart enough to use those tags and generate a basic preview card, but there are tools to augment the look of this card. The two most popular are Twitter’s Card Components and Facebook’s Open Graph Image. Hooking into these protocols is as easy as adding some extra "meta" tags to the page’s "head", but it’s important to know the data type each tag is expecting.
