Following are some basic techniques:

1. Your page must be a valid HTML document. Most internet sites are not valid. Check your site at http://validator.w3.org and fix errors if there are such.

2. You also must have a well structured HTML document. Many people crossing html tags like this : <form> <table> ... </form></table>. Never do that. Use careful tags H1 H2 .....
