When we embed any YouTube video, it has a YouTube logo over its control bar. Obviously, logo stands there to advertise YouTube. But it may drive traffic away from our site. So one may wish to embed Youtube videos without Youtube logo. The feature is called modestbranding.
This feature removes youtube logo from control bar. But YouTube logo appears on the corner of the video when somene hovers over it. But this reduces the chances of it being clicked. So I think one should implement it, especially when you are embedding someone else's video.
Video with the YouTube Logo:
Video without YouTube Logo:
Following is the i frame embed code shown below:
<iframe width="560" height="315" src="http://www.youtube.com/embed/iDIrr7OTuFk" frameborder="0" allowfullscreen></iframe>
Just add ?modestbranding=1 as shown in the code below:
<iframe width="560" height="315" src="http://www.youtube.com/embed/iDIrr7OTuFk?modestbranding=1" frameborder="0" allowfullscreen></iframe>
This is remove YouTube Logo from your player control bar. Also please note that underlined URL represents the URL of the video watch page. It will be different for different videos. All you have to do is add ?modestbranding=1 after URL.
If you are also using rel operator to switch off the related results at end of the video you may need to separate rel parameter from modestbranding parameter with the help of ";". So code would be as follows:
<iframe width="560" height="315" src="http://www.youtube.com/embed/iDIrr7OTuFk?rel=0;modestbranding=1" frameborder="0" allowfullscreen></iframe>
