Before I show you a great command, you must understand that all META commands must be placed in the HEAD section of your HTML code. That is, somewhere between the <HEAD> and </HEAD> tags.
Here is the code that did it.
Just change the X to the number of seconds you want and change yourpage.html to the HTML page you want to load. The page address can be expresses as either a relative or an absolute URL. Also, if you want your page to simply refresh you can leave out the URL address; CONTENT="X".
Search engines will also look for META statements or tags. There are several which are commonly used. Always use at least the keywords and description. Some possibilities are shown below.
Let us take an example. Suppose I want to create some META statements for my NBA Orlando Magic Basketball Fan Page. I don't actually have one, but lets do it anyway. For the author content I would put my name, because I wrote it.
For a description I could make a big long statement bragging about the great Magic team, but I'll keep it simple.
Then for keywords I could use just about anything related to the team or basketball in general. The more keywords you use, the more exposure your page will get. Keep it mind that most search engines have a built in limit to the number of characters for keywords. Keeping that in mind, always put the most important keywords first.
Notice that I was very specific at first and then became very general with keywords like sport and ball.
The rest of the META tags are not used much, it's really up to you. I'll show you some examples for our imaginary page. The expiration tag is an interesting one, because it tells the search engine to automatically delete your page's submission after that date.
Keep in mind that not all search engines are alike. Some may only request your URL address of your home page while others may want a full page of information. Some may use your META description and some may not. Some may take as long as two weeks to add your home page to their listings and some may do it a in a manner of seconds. Sometimes it may feel like a fighting battle just to advertise your page! Just stick with it.
