You really don't need to be an influencer to start affiliate marketing all you need is good communication skill and marketing a good product when you have a good communication skill people will listen to you and buy the product and they will refer there friends that is how you grow.
In affiliate marketing you will surely grow and become successful but you need time to grow.
Yes I know that but the bigger advantage is with the influencers that have already their own community and can ask them to sign up for them if ever they need that service they're advertising or the products that they endorse with their affiliate links. This is easier for the girly influencers where simps are going to sign them all they long and going to avail products and services where they're going to get a lot of commissions and this isn't a secret to all.
What if the girl influencer also sells girl products? I don't think a man will avail it lol even though they like that streamer so much, same goes if the streamer is a man and the audience are women. It's already a different story if they buy for their partners, siblings, friends... Apart from their own community, videos of influencers can easily go viral and other people can see them or interact on the links that they are posting.
This is the dream of those who want to sell something but we need to take it easy because being one is like winning in a lottery. Many have tried and do their best but they still ended up being a failure. We can only try other opportunities out there and maybe there is that one that will click on us.
