Make sure you include your business information at the bottom of every page on your Web site.
The information should include your:
Business or company name
Full address, including country
Telephone and fax number
Email address(es)
Web site address, if it's not already displayed at the top of each page
When your users print out your site's Web pages and refer back to it weeks, or even months, later, they will know exactly where they got the information from.
