Most of the modern websites have RSS feeds available that lets you easily follow updates without leaving our feed reader.
If you are wondering what are RSS feeds, here is a great video explaining what RSS feeds are.
Unfortunately, not all websites in the Internet have RSS feeds. There have been many webpage monitoring services that will notify you when a webpage you are watching changes or updates.
Google Reader can now track changes to any web page even if there isn’t a RSS feed available. You can add any website URL to the ‘Add a subscription’ box in Google Reader. If it can’t detect a RSS feed, Google Reader will prompt and ask you if you want to ‘Create a Feed’ for this page.
Google Reader will periodically visit that page and check for changes and publish any changes in the custom feed you created for the page.
This is a great way to follow up on changes to web pages you are interested in, as a reader.
If you are a publisher and you intentionally don’t provide RSS feeds for parts of your site and don’t want Google to crawl it, you can use this link to opt-out.
Google Reader has been adding little useful features lately and this is definitely another step in the right direction.
