Hi there,
It's always interesting to learn about how other SEO businesses operate. The number of clients an SEO business services per month can vary depending on the size and resources of the business. Some businesses may have a higher volume of clients but provide a more basic level of service, while others may have fewer clients but offer more personalized and comprehensive services.
As for specific tasks, it depends on the business and the client's needs. Some businesses may assign specific tasks to different team members with specialized skills, while others may assign one person to oversee the entire website optimization process. The key is to find a workflow that is efficient and effective for both the business and the client.
