First off let's not assume everyone knows what SEO and CMS means.

SEO stands for Search Engine Optimization. Basically this means optimizing your website so that search engines love you and your content.

CMS stands for Content Management System. A CMS allows the owner of the site, you!, to easily add, edit and delete content on the site. That means text, images, blogs, videos, pages, etc.

So why do you need a good CMS to get great SEO? The reason is simple, search engines love fresh content. If you aren't regularly updating your site you are essentially sending a message to the search engines, and your visitors that says "I don't care about this website and therefore I don't care about you". I know that seems a little harsh but it's true.

Imagine you owned a record store and never had the newest releases. Sure, some people might want to come by for a while to check out your old inventory but eventually your traffic would dry up with no new inventory. The same goes for your website. You need to constantly feed your site with fresh content or your visitors, and eventually your business, will dry up.

But if you get in the habit of adding fresh content on a weekly or even daily basis then you will be pleasantly surprised by the increase of traffic and interest from search engine generated leads. I personally prefer blogging since you can post little blogs like this one and Google will quickly index it for search keywords and start driving traffic your way.

So if you are serious about using the web to grow your business, and who isn't these days, then make sure your website has a robust and easy to use CMS. And then make sure you use it on a regular basis. You will not be disappointed with the results.
