Cardshifter website meta-tags for SEO
1. Charset


&lt;meta http-equiv="content-type" content="text/html; charset=UTF-8" /&gt;



You declare a HTML5 doctype and two charsets. You can remove the first of the two rules and leave this:

  &lt;meta charset="utf-8"&gt;


2. IE rendering engine


&lt;meta http-equiv="X-UA-Compatible" content="IE=edge" /&gt;



The browser should choose the fitting rendering engine on its own. Setting IE=edge should do nothing in most cases unless the default rendering engine was changed by the user.

That said, it doesn’t do harm.

3. Comments


&lt;!-- META-TAGS --&gt;



Don’t state the obvious. We can see every &lt;meta&gt; thing is a meta tag. Also there are other things under this comment as well. title and link are not meta tags.

I’d also leave out comments like the ones for twitter tags. Separating them by new lines creates enough distinctiveness.

4. HTML Shiv/Shim


&lt;!--[if lt IE 9]&gt;
  &lt;script src="https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js"&gt;&lt;/script&gt;
  &lt;script src="https://oss.maxcdn.com/respond/1.4.2/respond.min.js"&gt;&lt;/script&gt;
&lt;![endif]--&gt;



Don’t omit the type attribute for browsers that don’t understand HTML5, because it is not valid HTML 4/XHTML. You include the shiv to ensure IE8 support for HTML5 elements, so you should definitely have it there.

&lt;!--[if lt IE 9]&gt;
  &lt;script type="text/javascript" src="https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="https://oss.maxcdn.com/respond/1.4.2/respond.min.js"&gt;&lt;/script&gt;
&lt;![endif]--&gt;


4. SEO

Having a good structured document is the one thing which helps. You have description that search engines use, you have a page title, you probably will have fitting headings in your actual content.

However that’s just the foundation. With just that, search engines won’t give you a good ranking. The important part is the content. Make sure you have a good document outline.
