Sites like Zyoin and WiseStep connect employers with prospective employees, many of whom are already employed and not actively job-hunting via networking. The main benefit is knowing who these qualified candidates are. Rewards for referring a candidate who gets hired range from $50 to potentially several thousand dollars. If you know a stream of job-seekers, this is a great way to break into the recruiting business without the need for overhead costs.
If my piece of content is so unique and valuable around hiking backpack recommendations, that other reputable outdoor websites are willing to link to it and build the page’s authority, then I’d have a very real opportunity to rank high in organic search for these search terms (meaning, my page will come up first when someone searches for hiking backpacks).
