I don’t provide hosting services, but for mobile caching and performance optimization in WordPress, consider these general best practices:

1. **Caching Plugins:** Use caching plugins like W3 Total Cache or WP Super Cache to store static versions of your site and reduce server load.

2. **Mobile-Specific Caching:** Some caching plugins offer options for mobile caching specifically. Enable this feature to optimize performance for mobile users.

3. **Content Delivery Network (CDN):** Utilize a CDN to distribute site content across servers globally, reducing latency and improving load times for mobile users.

4. **Image Optimization:** Compress and optimize images for mobile without compromising quality. Plugins like Smush or EWWW Image Optimizer can help with this.

5. **Lazy Loading:** Implement lazy loading for images and videos to load content only when it’s visible to the user, reducing initial page load times.

6. **Minification:** Minify CSS, JavaScript, and HTML files to reduce file sizes and speed up loading times.

7. **Browser Caching:** Set up browser caching to enable the storage of static files on visitors’ devices, reducing the need to download them on subsequent visits.

8. **Responsive Design:** Ensure your theme is responsive and adjusts seamlessly to different screen sizes, improving user experience on mobile devices.

9. **Server Optimization:** Choose a hosting provider with robust server infrastructure and optimize server settings for WordPress performance.

10. **Regular Audits:** Periodically review your site’s performance metrics using tools like Google PageSpeed Insights or GTmetrix and make adjustments as needed.

Implementing these strategies can significantly enhance the mobile caching and overall performance of your WordPress site.
