I use FeedBro to find feeds. FeedBro is also a reader, but I don't use that feature.
Once you've added the extension to your browser, click the icon and you'll see an option to Find Feeds in Current Tab
. It may or may not find one, and this may or may not be because the website doesn't have one. It's possible the website does have a feed but it's not listed on the current page.
If the button doesn't return a feed, you can try a few more things:
- Ctrl/Cmd + F for rss or atom or feed
- Google the website name + rss feed or atom feed
- Add
/feed
or/feed.xml
to the end of the base URL (eg,notes.samfeldstein.xyz/feed.xml
If none of those work, the site probably doesn't have a feed.
