SEO can help bring steady traffic to your affiliate opt-in page, but it usually takes more time to see results. You can write helpful blog posts or create pages that answer questions people are asking about your affiliate topic. If your content shows up on search engines, more people can find your opt-in page without paying for ads. To make it work well, the page should have a good headline, clear offer, and simple form where people can enter their email. Using the right keywords in your content also helps search engines understand what your page is about. Over time, if your content keeps getting views, you can grow your list without spending money on ads. SEO takes patience, but it can give long-term results. What type of content do you think people might search for that would lead them to your opt-in page?
