Google AJAX Feed API seems to be the quickest way to embed an RSS Feed to your website or blog. Embedding the RSS Feed is quick and simple if you use that tool, and it should just take a few seconds for you to do that.
Go here, choose the layout of the embedded RSS feed widget. It can be a normal vertical layout, a vertical stack, or a horizontal bar that streams articles from your RSS Feed.
Click Preview to check out a preview of the widget, and then click Generate Code.
Copy and paste the generated code on your site and you’ll see the RSS feed embedded along with other elements on your web page.
However, you cannot specify a feed URL directly â€“ there’s no option to do that. If you’ve got a blog, just type in its name and the Google AJAX Feed API will automatically discover the feed of that blog. If auto-discovery fails, you can manually edit the feed URL in the code.
