Unlike other YouTube plugins, It doesn’t replace your on-page video embed code with JavaScript/HTML code. Loading a video with JavaScript doesn’t provide any video SEO benefit as a search engine crawler will only see some code instead of the actual video object.
Simple YouTube Embed is easy to use because there is no setting to configure. It uses the oEmbed API so your videos will be responsive and provide all the benefits that core WordPress YouTube embed has to offer. YouTube videos on your website will continue to work even if you choose to deactivate the plugin.

</code></pre>
YouTube Video Autoplay

</code></pre>
Related YouTube Videos

</code></pre>
YouTube Video Controls

<pre><code>https&#58;//www.youtube.com/watch?v=Vpg9yizPP_g&controls=0
</code></pre>
YouTube Video Fullscreen
If you do not want to allow fullscreen option in the player you can add “fs=0” to your YouTube URL.
<pre><code>https&#58;//www.youtube.com/watch?v=Vpg9yizPP_g&fs=0
</code></pre>
YouTube Video Mute
To start a video in the muted state you can add “mute=1” to your YouTube URL.
<pre><code>https&#58;//www.youtube.com/watch?v=Vpg9yizPP_g&mute=1
</code></pre>
YouTube Video Playlist

</code></pre>

<pre><code>https&#58;//www.youtube.com/watch?v=Vpg9yizPP_g&iv_load_policy=3
</code></pre>
Video annotations are shown by default.
<h3>YouTube Advanced Parameters</h3>
With the Advanced Parameters extension you can use additional advanced parameters in your YouTube videos.
color
This parameter specifies the color that will be used in the player’s video progress bar to highlight the amount of the video that the viewer has already seen.
<pre><code>https&#58;//www.youtube.com/watch?v=Vpg9yizPP_g&color=white
</code></pre>
Valid parameter values are red and white, and, by default, the player uses the color red in the video progress bar.
Note: Setting the color parameter to white will disable the modestbranding option.
disablekb
Setting this parameter’s value to 1 causes the player to not respond to keyboard controls. The default value is 0.
<pre><code>https&#58;//www.youtube.com/watch?v=Vpg9yizPP_g&disablekb=1
</code></pre>
end
This parameter specifies the time, measured in seconds from the start of the video, when the player should stop playing the video. The parameter value is a positive integer.
<pre><code>https&#58;//www.youtube.com/watch?v=Vpg9yizPP_g&end=10
</code></pre>
The time is measured from the beginning of the video and not from the value of the start player parameter.
start
This parameter causes the player to begin playing the video at the given number of seconds from the start of the video. The parameter value is a positive integer.
<pre><code>https&#58;//www.youtube.com/watch?v=Vpg9yizPP_g&start=5
</code></pre>
loop
This parameter causes the video to play repeatedly. The parameter value is a positive integer (e.g. loop=”1″).
In order for the loop feature to work, the video needs to be turned into a single-video playlist as well.
<pre><code>https&#58;//www.youtube.com/watch?v=Vpg9yizPP_g&playlist=Vpg9yizPP_g&loop=1
</code></pre>
