How Does Podcasting Work?

It has been said that in October of 2004 a Google search returned less than 6,000 results for the term "podcasting". Today, a similar search yields more than 857,000 results. Like the blogging phenomenon, podcasting has come out of nowhere and attracted an enthusiastic following.

While some traditional radio talk shows have begun providing podcasts of their regularly-scheduled broadcasts, the bulk of the podcasts that have cropped up tend to be independent broadcasters who have a fascination with technology. As a result, some podcasts are a little rough around the edges. Nonetheless, it is clear that the technology provides a significant opportunity and potential. Even nay-sayers believe that podcasting is more than a passing fad.

Podcasting is RSS that is used to syndicate and distribute audio files. Podcasting contains an audio file in the RSS feed's enclosure tag. An enclosure tag is used in RSS feeds to include certain types of files. The file contained in an enclosure tag can be: an image, a data file, a video file, or an audio file. Podcasting specifically refers to RSS feeds that contain audio files in their enclosure tag. The RSS version that currently supports enclosure tags is RSS version 2.0. All podcasts are currently created using this specification.

The benefit to podcasting is the fact that users can sync content with their media player and listen at a time and a place of their choosing: radio on demand. And while this technology is not limited to music, it seems to be the area that has received the most attention.

Podcasting is generally inexpensive to implement. Investment in a good quality microphone will ensure that the recording is audible. Depending on knowledge and experience, some podcasters invest in audio conversion, compression and audio editing software applications. Also, web space bandwith and software to create the feed for the podcast is needed. All in all, the initial expense is relatively small.

Publishing Podcasts
In three simple steps, independent broadcasters can have their voice heard:

1. Publishers create audio content, posting it on a website for listeners.

2. Create or edit an existing RSS feed including a link to the audio file in the "enclosure" field of an RSS 2.0 feed, uploading it to a website.

3. Tell the world that a podcast is available.

Listen to Podcasts:
In three simple steps web surfers can listen to podcasts:

1. Download a news aggregator or RSS reader that supports podcasting or sync a wireless device like an iPod with your computer.

2. Enter the URL of the podcast feed into the news aggregator or podcast management software.

3. As new items appear in the aggregator, review the podcast's description and listen to those that are of interest.

As popularity increases it is likely many voices will be drowned out, but for now, an independent broadcaster with a microphone and unlimited bandwith can make a name, create an image and change the world.

Steps to Creating RSS Feeds

RSS, or Really Simple Syndication as it is commonly known, is a technology that gives webmasters the ability to easily distribute and publish syndicated content on the Internet. It seems like all Internet businesses now have RSS feeds available; at least your competitors do. You have finally made the decision that you have to have one. Where do you start?

Steps to Creating an RSS feed

1.) Build a Feed

There are a number of desktop and web applications available that make feed creation easy. I would encourage anyone creating a feed to use one. Though not overly complicated, hand-coding an RSS feed can become a bit confusing and time-consuming. Most desktop software applications for building a feed include a wizard and contact-sensitive help, simplifying the process of creating a feed. Following a few simple steps in a wizard generally will produce an RSS feed in just a few minutes.

Publishers control what information is syndicated in the RSS feed, so ultimately it is the publisher's decision as to whether to include teaser copy or full articles. Consider what you are trying to accomplish and who your target audience is when building the feed.

2.) Transfer the Feed Onto Your Server

Once you have constructed an RSS feed you will need to transfer the feed to your server. This can be done using a standard FTP client (if it is not built into the feed creation software). The feed is usually placed in the domain's root directory like this: http://www.mydomain.com/nameoffeed.xml , but as long as you know where it is it doesn't really matter.

3.) Display the Feed on Your Website Using a Graphic of Some Sort

In order to signal to website visitors that an RSS feed containing content related to the website is available, include a colorful graphic on the website. It has become a standard that nearly all websites that have RSS feeds available use colorful graphics such as flags as indicators that RSS feeds are available for specific content. The flags were initially bright orange rectangles but as the popularity has grown, webmasters have bent the rules a bit. NotePage has made a free online RSS graphic tool available that allows users to quickly customize buttons by selecting the text on the button and the color scheme of the button. Once the color and text is entered, a custom graphic is instantly created. Webmasters can easily match the style of the RSS button to a website's theme. Graphics experience is not required. Simply select alternative colors and insert text to personalize RSS feed graphics. The RSS graphics tool can be used by clicking the following URL http://www.feedforall.com/public/rss-graphic-tool.htm or choose ready made graphics fom: http://www.rss-specifications.com/rss-graphics.htm .

4.) Include Information in the HTML of the Web Page So RSS Readers Auto-Detect Your Feed

After publishing an RSS feed it is important to let visitors know that the feed exists. Aggregators will automatically detect RSS on a website if you add a small bit of code in the header field of an HTML page.

Be sure to replace http://www.yourdomain.com/rss.xml with the URL to the RSS feed.

5.) Display the Feed's Content on a Website

Contents contained in an RSS feed can be added to a website, providing site visitors an alternative method for viewing the content. The information will also help increase search engine interest. Displaying the feed as HTML can be accomplished. Providing fresh content on a regular basis will encourage site visitors return.

6.) Submit the Feed to RSS Directories and Search Engines

As a rapidly increasing number of content sources, new and old, migrate or add RSS as a key distribution channel, and as more people utilize RSS newsreaders and aggregators to keep themselves informed, the ability to maintain high exposure and visibility is gradually shifted from complete attention to major search engines and content optimization techniques to an increasing awareness of RSS feed directories and search tools.

In order to increase exposure of an RSS feed it should be submitted to RSS search engines and directories. This can be done manually. Just as you would submit the URL of a website or web page to a search engine you will need to submit the link of the actual feed located on your website to the RSS directories. There is a large list of RSS directories at http://www.rss-specifications.com/rss-submission.htm .
