The Chairman’s Role is a business based in Devon and I built their website using WordPress as a CMS.
WordPress is great for a business website, since it is flexible enough to scale easily and can quickly be changed to respond to business needs.
There’s an integrated email newsletter system and a blog for updates.
Of course, SEO is built into the website from the ground up. This is the only way to do it. SEO is not a bolt-on option.
