links packages

HI,

There are a lot of link building packages available on here from various sellers - I have tries some out to varying levels of success.

Is it possible to tell which (if any) packages a site is using to rank by looking at a link profile?

thanks

Most of the service providers offers same type of link packages, we can find the links but not the exact package. Suppose if they use SAPE or PBN links then we can have some chance of identifying.
