Websites are publishing platforms. To get things done fast with the least amount of effort ( something I’m highly in favour of ) you need something that will let you create & maintain a site without a lengthy learning curve. It’s most easily done with WordPress.
This applies particularly to SEO ( actions taken to do well in search results ) and over the last 5 years, I’ve moved most of our marketing clients onto WordPress.
This is what Matt Cutt’s says about the platform – he’s one of the BIG heads at Google and his every word is hung onto by SEOers !!!
All trade-offs considered ( and there are some ) currently WordPress is way in front of anything else out there for ease-of-use and WAY less effort.
