By using the so called HTTP-EQUIV tag you are able to add certain values to your website. HTTP-EQUIV meta tags define the header of an HTML document. This is a section of code that is sent to your browser before the rest of the page. It communicates to your browser certain introductory information about the page. You can think of it as a "Hello, I am a HTML page. I was born on such-and-such a date and live on such-and-such a server. I was last modified on such-and-such a day, etc...

Where do you add this http-equiv= tag?

You may add this http-equiv= tag to all of your webpages, so not only in the first index page. Make sure that on every page relevant meta tags are added. Add keywords and phrases that are relevant and correspond to the text and the language on that specific page. It might be a lot of work to add specific meta tags to each page but you will notice in time that it works!

还要注意

HTML 4.01:元 http-equiv="content-type"content="text/html; charset=UTF-8"

HTML5:元字符集="UTF-8"
