What is WordPress theme development?

WordPress theme development is the process of building a unique template for your website from scratch, rather than relying on pre-made themes or builders. At Fooz, this means translating your design into clean, native components that ensure performance, scalability, and SEO compliance.

Do our themes support the latest WordPress updates?

Our custom WordPress themes are always built according to the official WordPress roadmap. This guarantees that they support the latest updates and remain compatible with future WordPress versions.

How do we ensure the performance of our themes?

We ensure performance in WordPress theme development by writing hand-coded components, minimizing plugins, and conducting strict code reviews and QA testing. Each project is optimized to achieve excellent results in Core Web Vitals and PageSpeed Insights.

How long does it take to develop a custom WordPress theme?

Developing a custom WordPress theme usually takes between 300–400 hours for standard projects. Larger, enterprise-level themes can take 600 hours or more, depending on complexity and requirements.

Can we integrate third-party plugins with the custom theme?

We can integrate third-party plugins with a custom WordPress theme if needed, but we prefer creating direct API connections. This approach offers better performance, security, and long-term reliability than relying on multiple plugins.

What are the benefits of custom WordPress theme development?

The main benefits of custom WordPress theme development are technical quality, scalability, and editor-friendliness. With a clean, future-proof build, your website is easier to optimize, expand, and adapt to new business or SEO requirements.
