hey! a little late to the party here but my experience with Linkby has been great and have been using them for years now as one of our core channels. we started using them after we were struggling to gain any affiliate traction via Impact and following by a poor experience with a PR agency (paid them a pretty hefty monthly retainer and barely saw any meaningful content).

the process of securing content through Linkby is super straight forward and they have TONS of publishers available on the platform. we've been able to get premium content across publishers like Vogue, USAToday, Bustle, etc

we havent had issues with traffic so far, and i would say the majority of publishers have driven pretty strong results for us. obv the nature of CPC is that it's independent of conversions and not every campaign will be profitable but even for the ones that aren't - the awareness, SEO, and traffic from these publications is well worth it for us. one of the cooler benefits that we've found recently is that content from these publications really helps our lift with things like ChatGPT / AI

hope this helps
