It’s very easy to build out your own site with your own videos for free. All you need to do is upload the videos to YouTube first. There’s no charge and we will cover hosting and streaming costs. It’s not only a great way to increase user engagement on your site, but it’s very easy, and free as well.

Once you have uploaded the videos you have a few ways of pulling them back to your site:

1. Embed videos one-by-one: Go to the video that you want to put on your website, and look for the ‘Embed’ box underneath the video player. Copying the HTML code that’s there into your blog will create an embedded player; the video will play within your site when the user clicks on the ‘Play’ button.
2. Pull videos back to your site dynamically: Creating a feed of your most recently uploaded videos is quick and easy. You can export feeds of your most recently uploaded videos; your favorites; or playlists. So if you want to be able to choose which videos the feed displays on your site easily, you can just favorite them on your YouTube channel or add them to a playlist. Find out more about this in our Developer’s Guide.

   If you have more than one channel you can either set up each feed or have one channel subscribe to the other channels and take a feed from the subscription of the original channel. There is more information in the Developer’s Guide.

3. Search through your videos: You can use the YouTube APIs to let users search YouTube directly from your site, pulling up results which can viewed without having to go to YouTube. Using APIs in combination, you can limit searches by user—i.e., your own uploaded videos—and control the number of results returned and whether they’re ranked by number of views or the relevance. For example, if you have content on your own YouTube channel, you can build an application using the code below that allows users to search only through your own videos, and then watch them without leaving your site.
