You realize you have to pay an employee to do that right? Odds are it’s still more cost effective to just buy ads.

"Organic" advertising though, the current big thing. It's the word-of-mouth from internet strangers. Supposedly converts better.

How do you go about trying to track the conversion rate on organic advertising-cum-Reddit post? It seems like it'd be impossible without the consent of Reddit.

You would use different metrics. It costs nothing to make the post so you can just pump them out, you don't need to use impressions as a metric anymore because you're not paying for impressions. Instead you get good at curating titles, images and articles that gain traction on the site. This isn't a wild idea, it's all over the reddit frontpage every day.

I don't understand the meaning of saying an employee is paid to do that. You might also pay a marketing agency to do it. The point is, Reddit doesn't get paid. As someone who uses Reddit everyday, I never see their ads, but I do notice posts that mention specific brands, websites, companies, etc.

the same can be said for instagram. it's called social media presence and it different than advertising.

On Instagram the poster matters, on Reddit the poster does not. This means it's completely different. A random made-up user on Instagram will have no audience, a random made-up user on Reddit will. Additionally, Instagram has an opportunity to form a relationship with the popular users and can control their accounts in specific if it wishes.
