CPL can make lead campaigns look cheaper than they really are when it is reviewed alone.
The first mistake is optimizing for low CPL without checking lead quality. Cheap leads that never answer, qualify, or buy are not cheap in practice.
The second mistake is ignoring lead-to-sale conversion rate. A $20 CPL with a 1% sale rate can be worse than a $60 CPL with a 10% sale rate.
The third mistake is comparing CPL across channels without revenue per lead. One source may generate fewer leads but much higher customer value.
