These are summaries for your posts or pages. They’re often displayed on your main blog page and in your Google Search results, anywhere your theme calls for it. There are two main ways they’re created. First, by taking a pre-determined amount of words or characters from the start of your content and tacking a “Read More” on the end. Second, you can write a custom description for yourself that will over-write that automatic ‘shortened-content’ option. This is worth doing for a few reasons, but the main one is usability. When you craft your own short summary you can make sure a compelling and clear message is presented to your visitors and they’re more likely to click through to read the rest.
