I have a simple website with 1 Logo as Header, 3 Buttons in the middle and a footer with some Text.
Now I was wondering, what the perfect header for a website would be for it to be SEO friendly.
This is what a previous Developer did (Replaced sensitive information with %):
<head profile="http://dublincore.org/documents/dcq-html/">
<link rel="schema.DC" href="http://purl.org/dc/elements/1.1/">
<link rel="schema.DCTERMS" href="http://purl.org/dc/terms/">
<title>% - %</title>
<link rel="stylesheet" type="text/css" href="style.css">
<link rel="icon" type="image/x-icon" href="favicon.ico">
<meta name="keywords" content="%,%,%,...">
<meta name="description" content="% - %">
<meta name="author" content="%" />
<meta name="Kategorie" content="%" />
<meta name="DC.title" content="%" />
<meta name="DC.creator" content="%" />
<meta name="DC.subject" content="%" />
<meta name="DC.description" content="%" />
<meta name="DC.publisher" content="%" />
<meta name="DC.contributor" content="%" />
<meta name="DC.type" content="%" />
<meta name="DC.format" content="text/html" scheme="DCTERMS.IMT" />
<meta name="DC.identifier" content="%" scheme="DCTERMS.URI" />
<meta name="DC.language" content="de" scheme="DCTERMS.RFC3066" />
<meta name="DC.relation" content="%" />
<meta name="DC.coverage" content="%" scheme="DCTERMS.TGN" />
<meta name="DC.rights" content="%" />
<meta http-equiv="expires" content="0">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="content-language" content="de">
<meta http-equiv="X-UA-Compatible" content="IE=8" />
</head>
My Question is: How much of this is actually needed? I heard DublinCore is obsolete, and meta names aren't really taken in consideration...so what would make a perfect head tag ?
