WordPress has a feed which is connected to the blog’s main query. What this means is that you can share a map of your blog posts, including by category, with external services.
This makes it handy for other websites to curate and display your blog posts, or choose from them when pulling in data.
I’ll give you an example. Lumen5 recently scanned my feed after I presented a blog post for processing. It was able to identify the various parts of the post like featured image, post title and body content.
In addition it was also able to identify other blog posts and give me a choice.
In a more traditional use case, feeds available via an email service like Thunderbird, are able to pull blog posts into your inbox.
To find the feed, you simply type your domain name followed by /feed
