Will affiliate datafeed sites still be SEO optimized?

Hello, Ive been reading about datafeeds, but i have a question about it.
If you use affiliate datafeeds, how would that provide seo for your site?
I probably just am not grasping the idea yet, so Im sorry if I am asking an obvious question.

Its just that If you just are using a script to pull data feeds into your site, then yoru site really doesnt have any content right? or am i wrong? therefore if you use a datafeed site, you cant really rank on that site can you?

  • I came across one site goldencan.com where they give you sample datafeed script and it’s basically only a few lines of code. so I dont understand how your site could show robots any content.
