The first thing you’re going to want to do is get set up with a content management system. These systems are the “backend” of your website, and handle everything for you.
Content Management Systems are so ridiculously powerful these days that you can have an excellent website with a variety of features up and running within minutes, then you can sit back and focus on content. And don’t worry – the CMS can dynamically manage your content too, adding it to the correct navigational menus etc.
There may be a slight learning curve, however don’t worry it is VERY easy to pick up.
As for what CMS to use? WordPress. Install WordPress. Unless you’re building some ridiculously custom built website, WordPress will suit your needs, and I estimate it will suit the needs of 99.9% of the people reading this article. It’s easy, it’s fast, and it’s just so simple to use. It’s what I use for 99% of my websites.
Even more importantly, it has a strong community which creates literally thousands of plugins and designs for it, so by using WordPress you will be saving yourself a bundle on custom coding and web designs.
