YouTube has hit yet another milestone, with the announcement that they have officially passed the 1 billion subscriptions mark and, to celebrate, they have launched a brand-spankin’ new subscription button widget for bloggers and site owners.

YouTube first introduced the yellow subscribe button to YouTube channel pages back in 2006. Since then, YouTubers have asked users to subscribe via annotations, in description links and linked to their subscription page from their blogs and websites. However, this is the first time that YouTube has provided an embeddable widget that YouTubers can add to their personal blogs and webpages to let their site visitors subscribe to their YouTube channel in a single click. Check out the widget below and feel free to click to subscribe to our YouTube channel!

The widget is really simple to embed. All you have to do is add the code below into the source code on your blog or website, just like you embed YouTube videos:

<iframe id=”fr” src=”http://www.youtube.com/subscribe_widget?p=[add YouTube Username here]” style=”overflow: hidden; height: 105px; width: 300px; border: 0;” scrolling=”no” frameBorder=”0″></iframe>

Don’t forget to insert your own YouTube user name into the brackets where it says “add YouTube Username here”, and be sure to delete the brackets as well. Here’s what my code looked like when I created a subscription widget for our SocialTimesInc YouTube channel:

The ability to let viewers subscribe to your YouTube page from your blog or website is likely to lead to a big jump in YouTube’s subscriptions. They just hit the 1 billion mark based on YouTubers subscribing from YouTube videos and channel pages alone. Opening up the door to subscriptions on blogs and websites could lead to even more YouTubers crossing the 100,000 or even million subscriber mark!

Do you plan to embed the new YouTube subscribe widget on your blog or website? Do you think YouTube will see a big jump in subscriptions thanks to the widget?
