Yes, they do. In no particular order:

• Do a View Source on the site's frontpage. You might see some HTML for "application/atom+xml" or "application/rss+xml". The URLs associated with those hrefs will be for the ATOM and RSS feeds.
  • If you search for one of the following in the HTML source you'll probably run into the feeds:
    • rss
    • atom
    • feed
    • json
• Look for a syndication page on the site. It should have links to the feeds.
• You might see the RSS feed icon or the ATOM feed icon on the page.
• Many CMSes (Wordpress in particular) automatically put them at /feed on the site.
