Previously, Google Blogs allowed people to search for a given keyword and subscribe to a RSS/ATOM feed for all blog posts on blogger.com around that given keyword. Now that this option does not exist anymore (deprecated in favor of Google Alerts), I am finding no good way of creating a RSS feed for web-wide news/blog posts/videos that center around a given topic. The context of my question is - I am developing an informative blog that centers around a given topic, let's assume it's a popular upcoming Video game or Software product. I'd like to be able to see in a centralized way - all new information that comes related to this topic. Although I can use Google Alerts, I prefer RSS or JSON output because I am piping this response, along with other collected information to a centralized dashboard that I use for my content marketing strategy (so I can more easily pick what's trending and what not around this topic).
