The best service for tracking topical news?

Question

Monitoring

I have a need to track news on a specific topic. Let's say all the news containing the word "iphone 6
" I am only interested in that part of the news that concerns, say, marketing, then I am not interested in reading the entries in the schoolgirl's blog.
Actually, I need a service that would look for interesting news for me, according to the given tags, only in the sources I specified.
Feedly got advanced search not so long ago, but it's still a search, not a separate feed with saved news.
I did not conduct serious research, maybe someone will immediately tell you the finished version?
Thank you.

Answer 1

Looks like you are looking for Google Alerts or Mention :)
Type in Google Alerts:
To get all the news of this resource for a given request by email or by rss ;)
The search is carried out there, as in Google .

Answer 2

Yes, I have already tried Alerts. Created an rss feed and added it to feedly. I just didn’t know that it was possible to differentiate by resources there. Great news, thanks!
I'll try Mention too.
