Common scalability options for hosting plans include:

1. **Vertical Scaling:** Upgrading resources like CPU, RAM, or storage on a single server to handle increased traffic or resource demands.

2. **Horizontal Scaling:** Adding more servers to distribute the load, often done through load balancing. This is particularly effective for handling increased traffic.

3. **Cloud Hosting:** Using cloud services allows for flexible resource allocation. Cloud platforms like AWS, Azure, or Google Cloud offer easy scaling by adjusting resources based on demand.

4. **Content Delivery Network (CDN):** Distributing static content across multiple servers globally to reduce latency and improve website performance.

5. **Managed Hosting Services:** Opting for managed hosting providers that offer automatic scaling based on traffic fluctuations, sparing users from manual adjustments.

When choosing a hosting plan, consider scalability features provided by the hosting provider and ensure they align with your website’s growth expectations.
