How To Measure Link effectiveness?

Hey all, I ordered several different link services to my affiliate site. My goal is to differentiate the services and to ultimately quantify how backlinks lead to more traffic.

What was your experience? Did you purchase backlinks and see an influx in traffic in several days? weeks? Months? Years?

You might say it depends on "quality" - which I guess could be another discussion - but I can't help but to think otherwise. Many of my competitors - at least it seems - have bought links.

i dont think buying links directly has a positive correlation on a sustainable traffic from the link source.

buying powerful links has a positive correlation with higher serp; hence resulting in more traffic.

It takes 2-3 months to see the effect of quality link building. Maintain consistent quality link velocity and your site will not only climb the SERPs, but also maintain a steady position during turbulent update times.

With a new site it's 6 months to see the result of its netlinking,
otherwise 2 months minimum on a site that is more than 1 year old.
