Keeping your site up to date after it has been launched is as important as creating the site in the first place. When information remains static, there is little reason for people to re-visit the site - and therefore the opportunity to promote new products and services is lost.
You may want to include a 'News' tab or 'Special offer' that changes regularly and encourages previous viewers to return to your site.
We hope you find this useful in helping you to plan your web site. There are many other things to consider when planning your site, but these guidelines will hopefully help you take the first steps into having a professional and functional web presence.
