Lets say I have 2 pages (1 for mobile and 1 for desktop)
Mobile URL: http://www.example.com/mobile/
Desktop URL: http://www.example.com/
And I put these kind of SEO tags in the <head>
of the desktop version of my site:
<meta name="description" content="Amazing Description"/>
<meta property="og:type" content="Website"/>
<meta property="og:url" content="http://www.example.com/"/>
<meta property="og:title" content="Perfect Title"/>
<meta property="og:description" content="Amazing Description For Social Media"/>
<meta property="og:image" content="http://www.example.com/img/awesome.png"/>
And finally, I put this canonical tag in the mobile page:
<link rel="canonical" href="http://www.example.com/">
Wouldn't that make it so that any additional tags placed in the <head>
of the mobile site were ignored?
If Google trusts your canonical link, then yes, only your desktop page would be taken into account.
