Squarespace accounts offer various plans that dictate the number of websites you can host under a single account. Below are the types of plans and their respective capacities regarding the number of websites you can manage:

Personal and Business Plans:

1. Personal Plan: This plan is designed for those building a simple, single website. It limits you to one website per subscription.

2. Business Plan: Similar to the Personal Plan, the Business Plan allows you to host one website under a single subscription. This plan offers additional features such as advanced analytics, promotional pop-ups, and e-commerce functionality.

Commerce Plans:

1. Basic Commerce and Advanced Commerce Plans: Both these plans are tailored for e-commerce and also limit you to one website per subscription. The higher-tier plans come with advanced e-commerce features like customer accounts, abandoned cart recovery, and more.

Squarespace Enterprise:

For larger organizations, Squarespace offers bespoke Enterprise plans which can provide services for multiple websites but are usually custom-tailored to each client’s needs. The details and pricing for these plans require direct consultation with Squarespace’s sales team.

Managing Multiple Websites:

If you need to manage more than one website, you have a couple of options:

1. Multiple Subscriptions: You can create multiple Squarespace accounts, each with its own subscription plan. Each account will be billed separately, and you can manage different websites independently of one another.

2. Managing Multiple Websites under One Account: Squarespace allows you to link multiple sites to a single account, even though each website requires its own separate subscription plan. This way, you can switch between websites using the same login credentials. This can be facilitated through the platform's "Site Switcher" feature.

Practical Steps:

1. Setting Up Multiple Sites:
2. Log into your Squarespace account.
3. From the Home Menu, click on your account icon.
4. Click "Sites" from the drop-down menu.

5. Then click "Create or Manage Sites" to start a new site or access existing sites.

6. Navigation:

7. To switch between sites, use the Site Switcher available in the account icon drop-down menu. This helps you seamlessly manage multiple websites without logging in and out.

Considerations and Limitations:

1. Costs: Each additional website will require a separate subscription, which means additional costs. Ensure your budget can accommodate multiple subscriptions.

2. Management Complexity: Managing multiple websites can become complex, especially if each site requires unique customizations and maintenance. Be prepared to allocate sufficient time and resources accordingly.

3. Domain Management: While Squarespace allows you to purchase domains through their platform, managing several domains can be cumbersome. Keeping organized records of domain renewals and DNS settings is crucial.

4. Third-party Integrations: Ensure that any third-party integrations, like email marketing tools, CRM systems, or social media platforms, are correctly configured for each individual website.

By understanding these details and being aware of the associated costs and management requirements, you can effectively decide on the best approach for having multiple websites on Squarespace.
