How Should I Structure a Content-Heavy PC Gaming Website?

I'm working on a PC gaming website with a growing amount of content, including game pages, guides, categories, articles, and recommendations.

I'm looking for suggestions on the best way to structure the frontend so the site remains easy to navigate and maintain as more content is added.

I'm particularly interested in:

Organizing large numbers of game pages Creating reusable page components Building clear category navigation Keeping the layout responsive Improving page-loading performance

Has anyone used a KeenThemes template such as Metronic for a content-heavy website? I'd appreciate any recommendations on the best project structure and frontend approach.
