Where to publish social profile links code your website?

Hi friends,
I can add to my social profile links to our website. I have some doubt is arise. Below code is social profile links code. This code put on each and every page on website (or) home page only. Please help me.

<span itemscope itemtype="http://schema.org/Organization">

<link itemprop="url" href="company url">

<a itemprop="sameAs" href="FB Page">FB</a>

<a itemprop="sameAs" href="Tiitter Page">Twitter</a>

</span>

 

It would be better to post the social profile link codes in the header section or footer section, so, you have no need to do insert code to all pages and it saves your time and efforts both.
Why only on home page? It is good to have the social icons on every page that is why I suggest you insert the code in footer or header section.

 

Are you running a wordpress site?
It would be easier to just install a plugin.

Otherwise put the code in the footer, on pages you want to have it on.

 

Just create a sidebar that is universal and shows up on every page of your site. And put the code in it. It will look more authentic in your wordpress site. We do it all the time.
