RSS feed

Why we use RSS?

With so much new content on the web being added daily, it can be tough to keep up with what’s happening online. There’s a number of different ways people try, including visiting specific websites every day, doing Google searches, or relying on social media to keep them informed. One solution that sometimes gets overlooked is an old-school one: The RSS feed.

What is RSS?

RSS is short for Really Simple Syndication and it’s a way to have information delivered to you. instead of you having to go find it.

If you’re visiting websites and blogs to see if there is anything new to read, you’re probably wasting a lot of time and not always finding anything new. RSS allows you to subscribe to a blog or website and have any new published information sent to you so you don’t have to go looking for it.

RSS is XML-formatted plain text. The RSS format itself is relatively easy to read both by automated processes and by humans alike. An example feed could have contents such as the following:

<?xml version="1.0" encoding="UTF-8" ?>

<rss version="2.0">
