Understand on the front end that your Web site will never truly be finished. It should constantly be tweaked and adjusted to make the user experience better, to respond to new input from the market, to relay new information. But beyond that, there are legitimate reasons your site should never “want” to be finished.
– Sites which are updated often are better indexed by the search engines, leading to higher rankings in the search engines than less frequently updated sites.
– It gives visitors to your site a reason to come back.
– You should consider having either a blog or a “Breaking News” page integrated into your Web site.
