By default, WordPress comes with a built-in RSS widget that you can easily place in a widget area of your WordPress site. Proceed as follows:
Step 1: In the WordPress backend, go to “Design”, to “Customize”, and then to “Widgets”. WordPress widgets are dynamic modules like the RSS feed that can be positioned on the front end of the WordPress site.
Step 2: First, select an area on your page where you want to insert the RSS widget. Click the insert block icon (square with plus symbol) at the desired location to select and add the RSS widget from the available list.
Step 3: The RSS widget will now be added to your website frontend (e.g. in the sidebar). Address your RSS widget by entering your WordPress RSS URL as the destination address.
Step 4: Customize the features by specifying how many posts or summaries of new posts are displayed under “More Options”. You can also add information such as date and author.
Step 5: Visitors to your website can now get an overview of the latest posts on your site itself in the RSS feed and subscribe to the RSS feed. By the way, you can use the RSS widget to collect and display not only your own, but also new posts from other websites.
Step 6: It is advisable to write a summary for each post, which can be displayed automatically in the feed. Summaries for posts can be added in the sidebar under “Settings” and “Read”.
