A good WordPress developer keeps plugins to a minimum, builds a theme that loads quickly, and hands you a site you can update without breaking it. A poor one leaves you with a slow site held together by plugins.
These five Cardiff developers are worth speaking to if WordPress is your platform of choice.
A note on this list: this website is run by Nathan Constance, who also runs NC Digital, the developer ranked first. The others are listed on their own merits, using their public Google profiles and the services they advertise.

Questions to ask a WordPress developer
Which page builder or theme do you use, and why? How many plugins will the site need? Who handles updates and backups, and what does that cost each month? Can I see a site you built two or three years ago? The answers tell you far more than a portfolio of new launches.
