Site management meta tags are used mostly by the people working on the website. While they may be interesting for your customers, they are typically more important for you and anyone editing your pages.
• author
Who wrote this Web page? You can include a list of authors if multiple people wrote the content and it typically refers to the content authors rather than the designers of the HTML or CSS.
<meta />
• copyright
Set the copyright date on the document. Note, you shouldn't use this instead of a copyright notice that is visible on the Web page, but it's a good place to store the copyright in the code as well.
<meta>

These meta tags provide information to the Web server and any
Web browsers that visit the page. In many cases, the browsers and
servers can take action based on these meta tags.
cache-control
Control how your pages are cached. The options you have are:
public (default) - allows the page to be cached; private - the
page may only be cached in private caches; no-cache - the page
should never be cached; no-store - the page may be cached but
not archived.
<meta http-equiv="cache-control" content="no-cache" />
content-language
Define the natural language(s) used on the Web page. Use the
ISO 639-1 language codes. Separate multiple languages with
commas.
<meta http-equiv="content-language" content="en,fr" />
content-type
This meta tag defines the character set that is used on this Web
page. Unless you know that you're using a different charset, I
recommend you set your Web pages to use UTF-8.
<meta http-equiv="content-type"
content="text/html;charset=utf-8" />
expires
If the content of your page has an expiration date, you can
specify this in your meta data. This is most often used by
servers and browsers that cache content. If the content is
expired, they will load the page from the server rather than the
cache. To force this, you should set the value to "0", otherwise
use the format YYYY-MM-DD@hh:mm:ss TMZ.

<meta http-equiv="expires" content="0" />
pragma
The pragma meta tag is the other cache control tag you should
use if you don't want your Web page cached. You should use
both meta tags to prevent your Web page being cached.
<meta http-equiv="pragma" content="no-cache" />
Control Robots with Meta Tags
There are two meta tags that can help you control how Web robots
access your Web page.
robots
This tag tells the Web robots whether they are allowed to
index and archive this Web page. You can include any or all of
the following keywords (separated by commas) to control
what the robots do: all (default) - the robots can do anything
on the page; none - robots can do nothing; index - robots
should include this page in the index; noindex - robots should
not include this page in the index; follow - robots should follow
the links on this page; nofollow - robots should not follow links
on this page; noarchive - Google uses this to prevent the page
from being archived.
<meta name="robots" content="noindex,nofollow" />
googlebot
Google has their own robot - GoogleBot, and they would prefer
that you use the googlebot meta tag to control the Googlebot.
You can use the following keywords to control the Googlebot:
noarchive - Google will not display cached content; nosnippet -
Google will not display excerpts or cached content; noindex -
Google will not index the page; nofollow - Google will not
follow the links on the page.
