After carefully testing (literally) thousands of themes over several years, there is now a core selection of WordPress theme providers that we personally use and recommend for WordPress based projects. Whilst you can get thousands of free themes from the WordPress Theme repository, if you're building a business site it can often pay to go with a premium theme provider to ensure that your theme will be supported over the long term and remain up to date with the latest web standards.
Genesis from StudioPress is the framework used on this site and our top recommendation, however all of the providers on this page have been vetted and used on multiple sites we've worked with. They are all professionally designed and updated frequently so you don't end up stuck with support headaches right after you launch your website.
StudioPress are the creators of the Genesis Framework for WordPress and were one of the original premium theme developers. They offer felixble and functional themes that are tightly integrated with WordPress and always utilise the latest features. All of their themes are now released as child themes on the Genesis Framework.
This is the theme for true “internet marketers”. It allows you to create solid lead generation pages (squeeze pages), sales pages, and membership site layouts with ease. Also offers many more features designed for conversion.
Theme Forest offer a wide variety of competitively priced and beautiful themes and templates for the web. Make sure you read the reviews and go with popular authors if you want your template to be supported over the long term. Credit loaded can be used across the entire Envato network giving you access to video, audio, code and much more.
WooThemes offer a wide selection of themes that look great out of the box. They are very active members of the WordPress community and offer tight WordPress integration however their themes are only recommended if you want to use them without many changes. So if you see a design you like and you are happy to just switch out the logo these are great!
