RSS feeds are a great source for extracting content from blogs, forums, social media and news sites. The convenience it has to offer is the availability of all the essential data points from a site at one place, with no unwanted elements. Scraping RSS feeds
can be useful for aggregating huge amount of data from content based websites which is essential for media companies and news aggregators.
If you want to crawl RSS feeds of sites that are into a particular niche, say fashion, the best route forward is to crawl popular blog directories. Blog directories would have an ever-expanding list of blogs from every category which makes it easier to crawl RSS feeds, site name and the URL using a custom crawler.
