1. Open the YouTube page containing the video you want to embed.
2. Just below the video window, find and click the Share button.
3. At the bottom of the "Link to this video" box, click Embed.
4. Below that, you'll see a highlighted chunk of text. This is the "embed code," which you'll need to copy and paste into your Web page. You can do so immediately by right-clicking the text and choosing Copy. However, you may want to modify some options first, as described below.
Notice the five checkboxes below the embed code. The one I have to enable most often is Use old embed code, which provides a different chunk of code that's more widely compatible with blog tools. Make sure to enable any of these options you need before copying the embed code.
