How to map Feed Importer with my content type?
How do I map that link with my content type? (note it's NOT the feed's link)


You're right your feed link is NOT a feed link. The URL is simply incorrect and this issue has nothing to do with Feeds module.

http://www.happynews.com/rss/.aspx returns 404 but when you dig a little you can quickly find that http://www.happynews.com/rss/ returns directories and other resources containing XML feeds. 

For example https://www.happynews.com/rss/environment.aspx is a correct RSS channel titled "HappyNews - Environment" where you can see &lt;item&gt; XML nodes and each nested &lt;title&gt;&lt;description&gt;&lt;link&gt;&lt;pubDate&gt; data.

To import such single channel you need:


create importer with HTTP Fetcher
and as a parser check Common syndication parser option
in fetcher settings you should provide RSS source channel link, so in Automatically add scheme input simply paste link to the channel you want to import like https://www.happynews.com/rss/environment.aspx
if right address is given Feeds fetcher will be able to"recognize" the scheme and all accessible fields should be visible on mapping tab in "Select a source" select field.


After all steps inluding RSS -> node fields mapping definitions you will be able to import data periodically (when CRON configured) or manually by running http://you-site-address/import 

You can also attach importer to specific content type, this way source is imported by creating a node of that content type.
