There is no specific number of followers that you need to have in order to start affiliate marketing. Some affiliates are able to be successful with a small number of followers, while others may have a larger following and still struggle to make sales.
That being said, having a large and engaged following can certainly be helpful in affiliate marketing. The more people you can reach with your marketing efforts, the more potential customers you will have. Additionally, a large and engaged following can help to increase the credibility and trustworthiness of your recommendations, which can lead to more sales.
Ultimately, the number of followers you have is just one factor to consider when it comes to affiliate marketing. Other factors that can impact your success include the quality and relevance of the products or services you are promoting, the value you provide to your audience, and your marketing strategies and tactics.
