Ciao a tutti, ho fatto validare il mio sito dal w3c, per migliorare il posizionamento all'interno dei motori di ricerca, ma mi risultano degli errori anche se ho copiato i tag da http://xhtml.html.it/guide/lezione/1710/i-meta-tag/.
Gli errori sono i seguenti e sono solo alcuni...
Qualcuno sa dirmi se devo o no chiudere i tag meta?
Li ho inseri nell'ordine come da guida html subito dopo il tag <head>
Grazie!!!!!!!!!!!!!!!!

The element named above was found in a context where it is not allowed. This could mean that you have incorrectly nested elements -- such as a "style" element in the "body" section instead of inside "head" -- or two elements that overlap (which is not allowed).
One common cause for this error is the use of XHTML syntax in HTML documents. Due to HTML's rules of implicitly closed elements, this error can create cascading effects. For instance, using XHTML's "self-closing" tags for "meta" and "link" in the "head" section of a HTML document may cause the parser to infer the end of the "head" section and the beginning of the "body" section (where "link" and "meta" are not allowed; hence the reported error).
# Error Line 7, Column 13: there is no attribute "NAME"
<META NAME =robots CONTENT="all">
You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead).
This error may also result if the element itself is not supported in the document type you are using, as an undefined element will have no supported attributes; in this case, see the element-undefined error message for further information.
How to fix: check the spelling and case of the element and attribute, (Remember XHTML is all lower-case) and/or check that they are both allowed in the chosen document type, and/or use CSS instead of this attribute. If you received this error when using the <embed> element to incorporate flash media in a Web page, see the FAQ item on valid flash.
