facebook like button is impossible to put on my website, SOMEBODY PLEASE HELP?

You put the URL of your website where I wrote google.com
If you want the like button to be specific for each page in your site, then add multiple like buttons, each with their own URL.
example: the help page's link would be google.com/help


<div id="fb-root"></div>
<script>(function(d){
var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js#appId=239388446108038&xfbml=1";
d.getElementsByTagName('head')[0].appendChild(js);
}(document));</script>
<div class="fb-like" data-href="google.com" data-send="true" data-width="450" data-show-faces="true"></div>
