Professionals do not leave anything to chance. The consequences of chances occurring are too risky and unpredictable. In professional web site design, the problem of chance can be taken care of by use of legal pages. These pages include things like privacy policies, disclaimers, trademarks, patents, copyright notices, terms and conditions and anything else that can put you at the risk of looking straight up at the judge on the stand. Since the list of legal pages is long, you cannot have all of them on the website, otherwise you are better off hosting a website that deals with resolving website legal issues. Depending on your website, you can determine what legal pages need to be added what need not. Evaluate what products and services you are offering and what can be done ot protect you.
If you have a website that collects any type of information, then a privacy policies page should be included. Such a page will cover the use of cookies, contact information for erasing private info, editing dates when the information is changed and third party sites information for those who might collect information like advertisers. Professional web site design dictates that all of you web pages should include a copyright notice. If you have a complicated copyright agreement, you may decide to have a separate page explaining the copyright.
Terms and conditions of use of documents on a site are also common legal notices on many sites. These terms and conditions explain what actions are allowed and disallowed on the use of a website content. It may include things like crediting the content and images from the site, situations where submitted content may be disallowed and whether registration is allowed for such posting of content. Unfortunately, it can be very difficult to enforce some of these terms and registrations. Professional web site design dictates that a user agreement should be included where a site uses user-submitted content or blog comments to cover things like who owns the content and permissions for it and to whom the submitted content is licensed to.
For companies having patents and trademarks, it is professional to include a page that details them. Any other corporate policies that customers should be aware of should also be included. While not exactly legal pages, complaints and feedback pages are also useful and can help reduce legal issues. Professional web site design by use of legal pages is both a protection and well, just plain professional.
