You should choose carefully which keywords and phrases you wish to use on a page by page basis. They should be reflected everywhere in your page. Some people make the mistake of repeating their keywords throughout their site. Some even have the same meta keywords and discriptions on every page. Most search engines will mark you down for this.
Your domain name is important.
Check out your competitors. What key words do they use.
H1 - H7 tags are also important.<H1> Your main onscreen title. </H1>
Alt command in your image tags are also important. <img src="picture.gif" border="0" height="23" width="100" ALT="keywords in here">
Some search engines also pay attention to the unseen lines, usually used as a reminder of where certain parts of pages are at. <!-- Stuff in here is not seen on screen. -->
The title <title> Your page title goes in here </title>tag is very important. You are allowed a maximum of 50 charactersin this tag.
A word of warning though. Do not over do it. My advice is to be honest with a touch of salespersonship on top. Too much and you may get blacklisted!
Get yourself a free email account like Hotmail or Yahoo. Register with a FFA network giving the affore mentioned free e mail address when you register.
