Identify your site on every page. Put your company's logo in the top left hand corner so that your visitors will never wonder if they are still in your site. Don't change your default link colors. The default colors are shown below. Most internet users have become accustomed to and expect links to be in these colors.
Frames violate the page model by slicing up pages into independent panes of content.
As a result, the use of frames may have a negative affect on basic activities such as bookmarking and printing. They also present viewing problems, especially when your site links to another site that uses frames. If a particular page isn't finished, don't have a link to it. In Conclusion I really believe that good website aesthetics is mostly common sense. If something doesn't feel right, chances are you shouldn't add it to your site.
