According to these statistics, the hourly rate charged by SEO consultants is more than double that of freelance SEO consultants. According to these statistics, the monthly advance payment range charged by SEO agencies and consultants is almost double that of freelance SEO. According to these statistics, the per-project fee charged by SEO agencies is more than 4 times that of SEO freelancers, on average. Many independent SEO professionals go from setting hourly prices to paying a monthly down payment once they have established a strong foundation of trust with a customer.
Monthly advances encourage long-term relationships, because when you're done working on a project, you're still working together. It should come as no surprise that more experienced SEOs charge significantly more than less experienced SEOs. It's important to note that SEO is an ongoing process and the cost can increase over time as the company grows and its SEO needs change. While there are elements of SEO that you can outsource to anyone, it's not easy to teach a customer that good SEO isn't a commodity.
