When you link back to your home page from other pages, you might want to skip some of the introductory information at the top of the home page. Using a link to a named anchor just below that introductory information will avoid presenting it to people who have already read it, making your pages seem less repetitive. Also, if any pages on your site are longer than two screens of information when displayed in a web browser, consider putting a link at the bottom of the page back up to the top.
Look through your web pages and consider whether there are any places in the text where you'd like to make it easy for people to respond to what you're saying. Include a link right there to your email address. You can never provide too many opportunities for people to contact you and tell you what they need or think about your products, especially if you're running a business.
