How to add more than one RSS Feed Link for wordpress

Text that is displayed after you click on browser RSS icon depends on the feed reader you are using. I don’t think you can modify what it displays directly through WordPress (correct me if I’m wrong).

A simple workaround to achieve something similar to what you want would be placing feed links to different categories. You can place a link for every category somewhere on the page using get_category_feed_link() function.

Edit:

Some feed readers (Chrome’s RSS feed Reader) get feeds from sites header. In this case you can get them to display feed by adding link directly to header.php inside the <head>. Link could be formatted something like this:

<link rel="alternate" type="application/rss+xml" title="Category1 feed" href="https://wordpress.stackexchange.com/questions/176718/<?php echo get_category_feed_link( get_cat_ID("category1' ) ); ?>" />
