all this java script in head necessary? Hurts SEO?

There's a big part of java script in the head my page cyberspace-casino.com. I'm worried if it hurts my SEO.
Have a look at this part:

<style type="text/css" media="all">/*<![CDATA[ */
img.wp-smiley,
img.emoji {

vertical-align: -0.1em !important;

padding: 0 !important;
}
/* ]]>*/</style>
<style type="text/css" media="print">/*<![CDATA[ */
#wpadminbar { display:none; }
/* ]]>*/</style>
<style type="text/css" media="screen">/*<![CDATA[ */

As far as I know this code enables "emojis" on your site. Do you use emoticons in your text and/or comments? If no, you can safely disable this code.
I don't use WP so I don't know if I can "direct you" on the right way but disabling this code looks pretty simple.

1. You can use this plugin (easiest way): https://wordpress.org/plugins/disable-emojis/
2. You can write a function (PHP) to deactivate it. The function needs to be placed in "function.php" file contained in your main theme folder.

And no: no effects on SEO.

It seems quite weird to me that they include this feature without a built in ability to turn it off. I mean, how many people are actually going to even use it?

But anyway, dfiocch beat me to it - you can disable it if you like.

I turned of the emoji feature but the code is still there.
Regarding SEO there should be readable text for the search engines as soon as possible. The script is in the head and not in the body part. NO problem with SEO?

I wouldn't worry to much about it. Google knows if you're using CMS like WordPress. My sites do okay and they're WordPress with a lot of code.

I found a plugin that is helpful to remove this and more.wp_head() cleaner

To me it is easier to use than the already installed head cleaner.

I often wondered this myself. Did the plugin work? Easy to use?

This one is easy to use. Installed it offers check boxes of what to display in the head and what not.

You'll screw up your site bro, meddling with code in that way.

First of all, it doesn't affect your on-page SEO but it does affect the loading time of the page. So in a way it does consequently affect SEO a bit.

Second of all, the way to remove it isn't to use any head cleaners, but to attack the very origin of the emoji code and instruct Wordpress to stop loading the emoji code altogether.

This, basically.

this plugin works on my site. See code now and before.

Valuable tip Dan, of course when I get around to using it I will spend an hour looking for the post again....

Why use a plugin, to remove something wordpress loads, when you can just tell wordpress to stop loading something?

When making changes to the functions file, stop and start the site since the functions file is read at site startup.

It's one of the basic stuff you unfortunately should do with every new Wordpress site.

Another one that tackles the same issue is the Heartbeat API, you need to turn it off for visitors who aren't logged in as admin.

Both of these things slow down the site, the other one significantly. Not sure if they solved the problem in the new Wordpress version though.
