On a web page without an RSS icon and link may still have an RSS feed.
The simplest approach is to install a browser extension that detects RSS feeds and makes it easy to copy and paste them. Extensions vary by browser.
Firefox - RSS Ticker
Safari - Syndicate
If needed you can use your browsers "view source" function to look for an RSS URL in the page source.
For example using IE11
Select the page function ->Source
Select the debugger tab
In the right hand corner in the search box enter RSS
You will find the found terms highlighted. An RSS feed is identified by RSS+XML. Select the URL in that line and copy it. It is the RSS URL.
