Hosting plans often come with resource limits for bandwidth, storage, and CPU usage. If your site experiences rapid growth or traffic spikes, you may exceed these limits, causing slowdowns or even outages. To manage this, monitor your resource usage through your hosting control panel. If you're approaching your limits, consider upgrading to a higher-tier plan, such as VPS or dedicated hosting, which offers more resources. Alternatively, optimize your website by reducing image sizes, using caching, and offloading large files to CDNs. Proactively managing resources helps ensure your site remains fast and reliable.
