Startup cost: $100 - $2k

Setup costs for starting an affiliate blogging side hustle range from $100 to $2,000. At the low end, the bare minimum expenses would cover domain registration, web hosting, and basic website design tools. On the high end, investing in premium themes, email marketing services, SEO tools, and social media automation platforms can enhance the blog's performance. Essential expenses include domain registration, hosting, and potentially a keyword research tool for content optimization. Optional expenses may include paid traffic for promotion or premium plugins for enhanced functionality. Hidden costs could arise from unexpected software subscriptions or outsourcing content creation. Online feedback suggests that initial costs can escalate once committed due to additional tools or services deemed necessary for success. If a friend wanted to take this seriously, I would advise budgeting between $100 to $2,000 for a well-rounded start in the affiliate blogging space.
