Depending on the engagement frequency, website support plans for an enterprise website can cost anywhere from $4,500 to $12,500 per month. Services can include website hosting, website updates, user experience optimization, conversion rate optimization, adding on components, security, project control and more. When planning your budget for a website support plan, it is important to consider the holistic tech stack which the website supports. For example, a website that sells products will need more website updates than a website that only provides information. A corporate website with an active resource center, videos, digital assets, and webinars will need powerful hosting and efficient code updates, a website that provides information to users in multiple languages will need more dedicated website hosting than a website in one language, and so on. The best way to determine the monthly cost of a website support plan is to understand the internal capacity of your team vs what you want your agency partner to take on a regular basis, come up with a quick RACI chart and it will help you with estimating the effort required.
