Why using a CMS is better than a normal website
Ease of Use
Your website is easy to update, but also easy to read and use by your visitors.
There are no broken links, design is consistant, the menu updates itself (+ sitemap) and the pages print beautifully (try it, you'll love it!).
Day to Day Running
Fixing that typo on your website only takes 10 seconds, adding a photo 1 minute, so you actually use your website, daily.
Your website is up to the minute up-to-date, and your visitors notice this. They will come back regularly to see what else has changed, saving you phone calls, faxes and endless paperwork. Because you use it, so will your visitors.
Search Engines
Website pages are built to excell with Google and all search engines. All you need to do is write the text, all the technical stuff is taken care of (meta tags, h1 tags, keywords etc), making for incredible results.
+ many more benefits, such as working from overseas, controlling your own business direction online, fast updates, no training...
Once you have used a CMS, you can never go back to a 'static', normal website.
